2019’s Bitcoin Miners Are 5x Faster Than Predecessors
Will crypto mining kill polar bears?
Bitcoin mining uses as much electricity as a small country. Many people hate it for this reason, its one of the more popular arguments against crypto currencies. Will crypto mining kill polar bears? I think not. I think it will help save polar bears. "Bear" with me. Germany produces a significant part of its electricity from renewable energy: wind and solar. As we all know, these sources are intermittent and seasonal, as is demand. When the share of renewable energy in the overall energy mix becomes large enough, the result is inevitable: temporary and seasonal overcapacity. This isnt just theoretical, energy prices in germany and the UK where effectively negative last Christmas: http://www.businessinsider.com/renewable-power-germany-negative-electricity-cost-2017-12//?r=AU&IR=T As explained in the above article, this isnt a rare freak occurrence, its expected and this will have to be become much more common if as a society, we want to transition away from fossil fuels. Because to do that we need (much) more renewable energy sources. A study I saw for Germany calculated they needed at least 89% more capacity, just to handle peak loads. But that also implies an incredible amount of overcapacity when demand isnt anywhere near peak, or when supply is above average due to favorable weather. Storing excess renewable electricity, in most places is very expensive and inefficient. So much so that its rarely even done. This is a major problem. Wind turbines are therefore feathered, solar panels turned off, excess electricity dumped in giant electrical heaters, offered for free or even offered at negative prices. Renewable energy may have become cheaper than other forms per KWH, but thats only if when you can sell all of your production. And its only true if the consumption occurs near the renewable energy source and not 100s or 1000s of kilometers further. Building capacity that can only be used 50% or even 10% of the time, or building infrastructure to store surplus electricity is still very expensive, as is transporting renewable energy over long distances. I know what you're thinking. Mining wont help here, because mining intermittently is something that seems crazy today; miners keep their expensive machines on 24/7. But thats only because today, the overall cost structure of a (bitcoin) miner is heavily tilted towards hardware depreciation. Particularly for anyone paying retail prices for mining asics. This will change completely, because of two related reasons: 1) mining efficiency improvements will taper off. Mining asics have been progressing extremely rapidly, from being based on CPUs and FPGA's, to using 20 year old obsolete 180nm process technology in the first asics, to state of the art 16nm chips today. This has resulted in at least a million fold improvement in efficiency in just a few years, which in turn lead to hardware investments that needed to be recovered in a few months or even weeks (!) before they were obsolete. Opportunity cost has been so high, that miners have literally chartered 747s to transport new mining equipment from the manufacturer in China to their datacenters in the US. This cant and wont last. 12nm and 7nm asics are about to be produced, or are being produced now. It doesnt get better than that today, and it wont for many years to come. Moore's law is often cited to show efficiency will keep going up. That may be true, but until now the giant leaps we have seen had nothing to do with moore's law, which "only" predicts a doubling every 18 months. Moore's law is also hitting a brick wall (you cant scale transistors smaller than atoms), and only states that transistor density increases. Not that chips become more efficient or faster, which increasingly is no longer happening (new cpu's are getting more cores, but run at comparable speeds and comparable power consumption to previous generations). What all this means is that these upcoming state of the art mining asics will remain competitive for many years, at least 3, possibly more than 5 years, and thus can be used and written off over that many years. But they will still consume electricity during all those years, shifting the overall costs from hardware to electricity. 2) Mining is still too profitable (for anyone making their own asics) and mining hardware is therefore still too expensive (for everyone else) Miner hardware production rate simply hasnt yet been able to keep up with demand and soaring bitcoin prices. This leads to artificially low mining difficulty, making mining operationally profitable even with expensive electricity, and this also leads to exuberant hardware profit margins. You can see this easily, just look at the difficulty of bitcoin. When the price dropped by 70%, did you see a corresponding drop in difficulty? No, no drop at all, it just keeps growing exponentially. That only makes sense because we are not yet near saturation, or near marginal electricity costs for bitmain & Co. Its not worth it yet for them to turn off their miners. Its not even worth it yet for residential miners. Another piece of evidence for this, is bitmains estimated $4 billion profit. But mining is a zero sum game, over time, market forces will drive hardware prices and the mining itself to become only marginally profitable. We're clearly not close to that -yet. You might think so as a private miner, but thats only because you overpaid for your hardware. Lets look at todays situation to get an idea. An Antminer S9 retails for $2300 and uses ~1300W at the wall. If you write off the hardware over a year, electricity and hardware costs balance out at an electricity price of $0.2/KWH. Anything below that, and hardware becomes the major cost. But how will that evolve? As difficulty keeps going up, bitcoin mining revenue per asic will decline proportionally, until demand for mining asics will eventually taper off. To counter that, prices of asics will be lowered until they approach marginal production costs, which by my estimate is closer to $200 than $2000. Let say a 1300W S9 equivalent at that point gets sold at $400 leaving bitmain a healthy profit margin; that would mean each year a miner would spend 5x more on electricity than on hardware. Hardware will remain competitive for more than a single year though. Say you write it off over 3 years, now you're spending 15x more on electricity than on hardware. Intermittent mining like 50% of the time, but with free or virtually free electricity will become economical long before that. By now, I will hopefully have convinced you of the viability of mining with intermittent excess renewable energy; intermittent mining with renewable energy will not only become viable, it will become the only way to do it profitably. Renewable energy at the source is already cheaper than any carbon burning source. Even in Quatar, they install solar plants because its cheaper than burning their own gas. Its transporting and storing the electricity that usually is the problem. Gas can easily be transported and stored. Wind and solar energy can not. And thats a massive problem for the industry. But mining doesnt need either. You can mine pretty much anywhere and anytime. All you need besides electricity, is a few containers and an internet connection for a solar plant or wind farm to monetize excess energy. Moreover, mining is a zero sum game, a race to the bottom. As long as its profitable for green energy providers to deploy more hardware (which will be true as long as they can at least recover their hardware investment), difficulty will go up. Until it becomes unprofitable for anyone who has to pay for his electricity. No one gives oil, coal or gas away for free, so anyone depending on those sources of electricity, can not remain competitive. If bitcoin price were to go up so much, that there isnt enough renewable electricity production in the world to accommodate the hashrate, bitcoin miners will simply install more solar and wind farms. Not because of their ecological awareness, but because it makes the most financial sense. And during peak demand periods, why wouldnt they turn off the miners and sell their electricity to the grid for a premium? Basically crypto mining would fund renewable energy development, and solve the exact problem laid out in the article linked above: provide overcapacity of renewable energy to handle grid peak loads, without needing any government funding or taxation on carbon based sources, without needing expensive and very inefficient energy storage. From the perspective of a green energy producer, energy storage, like a battery or hydrogen production, is just an expensive and intermediate step between producing electricity and getting paid for that electricity. Crypto mining will do the same thing, converting excess electricity in to cash, only much more efficiently. TL:DR, deploying more renewable electricity overcapacity is both very expensive and very necessary if we want to save polar bears. Financing for these large scale green energy projects will either have to come from tax payer money to store or subsidise the largely unused excess electricity, or it will come from crypto mining. Market forces will drive crypto mining to use the cheapest energy. Renewable energy already is cheaper per KWH than carbon based power, and nothing is cheaper than excess and thus free (or negative value) renewable energy. Bitcoin mining's carbon foot print will therefore become ~zero. If you take in to account the effect of financing and subsidizing large scale renewable energy development that can also be used to supply the grid during peak demand periods, its carbon footprint will be hugely negative. BTW, if you wonder what Blockchains LLC is going to do with 61K acres near Tesla's factory; my guess is solar plants and crypto mining. Expect to see renewable energy development and crypto mining to merge in to one single industry. Check out envion to get a glimpse of this future. Im not endorsing their token as an investment, I havent researched it at all, but the market they are going after is a very real one and its about to explode.
Samsung Asic Production: Does Bitmain Have a Competitor? Samsung ASIC Production and Market Impact
https://steemit.com/cryptocurrency/@jnem/samsung-asic-production-overview-does-bitmain-have-a-competitor Samsung Asic Production: Does Bitmain Have a Competitor? As many people know, BItmain currently has an effective monopoly on many parts of the ASIC market, with the most efficient Bitcoin miners being the S9. (There is the supposed Dragonmint 16T, but no one has seen that yet, so well see.) And seeing as how the S9 has been out for well over a year and a half, it seems that Bitmain would release the new supposed S11 anytime now. With the announcement of Samsung beginning production of ASIC chips, many have thought that a company of this size participating in ASIC production might knock Bitmain off their throne, but this isn’t the case. Is Samsung Making ASICS? The answer to this is no, Samsung, although becoming a producer of ASIC chips, will not directly produce ASIC miners. Samsung has only received orders from producers of ASICs for the production of the chips used in ASIC miners. Samsung has yet to clarify who ordered the chips, so it could be Bitmain or another ASIC manufacturer. Up till now, a Taiwanese company, TSMC, has been the main producer of the ASIC chips for miners. When Will Production Begin? It seems to have already started. In order to meet these orders, Samsung has specific “foundries” dedicated to the development of chips for external orders. These chips have been designed in order to strip all unnecessary functions and only leave hardware that is used in mining in order to both optimize hardware speed and electricity consumption.Samsung specifically stated that they have no involvement in how the chips are being used. Getting into this field seems to be a no brainer for Samsung as much of the tech used in producing graphic cards is also applicable to making ASICs. Who Are the Chips For? Although it is not known who the chips are for, there is a there is a company in Japan named GMO internet that has announced will be mass producing ASICs, and they have already produced a 12nm chip, with a 7nm in development. They have announced they will use these to mine for themselves as well as producing them for retail sales. Unless Bitmain or Canaan are switching suppliers, Samsung could be the supplier for GMO. This is on top of Japanese company SBI Holdings building a Bitcoin Cash mine after stating that it will use Bitcoin Cash for international payments. Once these miners are produced, unless Bitmain and others producer miners with the same size of chips, they will quickly be beat out of the market(The S9 and Dragonmint use 16nm) Is this going to bring the much needed decentralization of mining? Maybe. That remains to be seen. But it definitely is not a bad thing that more companies are getting involved in the ASIC space, as this allows for more development and more distribution of assets that will hopefully bring about the end of Bitmain’s effective monopoly and secure a much healthier and distributed Bitcoin mining space. Koreans, Do They Care? Um, I'm not sure about this one. I mean, there is news articles about it, so obviously it has some attention. But with electricity prices being high here, and most people liking Ethereum mining over Bitcoin, it doesn't seem likely that Koreans will be lining up to get ASIC miners just because a Korean company is help making them. On the Korean government side though, it may help regulators be a bit more lax on regulations. Seeing that the biggest company in Korea who touches nearly half the economy has skin in the Bitcoin game, the government might not want to hurt its own best friend by over regulating the industry, whether that be exchanges or mining.
https://seekingalpha.com/article/4152240-amds-growing-cpu-advantage-intel?page=1 AMD's Growing CPU Advantage Over Intel Mar. 1.18 | About: Advanced Micro (AMD) Raymond Caron, Ph.D. Tech, solar, natural resources, energy (315 followers) Summary AMD's past and economic hazards. AMD's Current market conditions. AMD Zen CPU advantage over Intel. AMD is primarily a CPU fabrication company with much experience and a great history in that respect. They hold patents for 64-bit processing, as well as ARM based processing patents, and GPU architecture patents. AMD built a name for itself in the mid-to-late 90’s when they introduced the K-series CPU’s to good reviews followed by the Athlon series in ‘99. AMD was profitable, they bought the companies NexGen, Alchemy Semiconductor, and ATI. Past Economic Hazards If AMD has such a great history, then what happened? Before I go over the technical advantage that AMD has over Intel, it’s worth looking to see how AMD failed in the past, and to see if those hazards still present a risk to AMD. As for investment purposes we’re more interested in AMD’s turning a profit. AMD suffered from intermittent CPU fabrication problems, and was also the victim of sustained anti-competitive behaviour from Intel who interfered with AMD’s attempts to sell its CPU’s to the market through Sony, Hitachi, Toshiba, Fujitsu, NEC, Dell, Gateway, HP, Acer, and Lenovo. Intel was investigated and/or fined by multiple countries including Japan, Korea, USA, and EU. These hazard needs to be examined to see if history will repeat itself. There have been some rather large changes in the market since then. 1) The EU has shown they are not averse to leveling large fines, and Intel is still fighting the guilty verdict from the last EU fine levied against them; they’ve already lost one appeal. It’s conceivable to expect that the EU, and other countries, would prosecute Intel again. This is compounded by the recent security problems with Intel CPU’s and the fact that Intel sold these CPU’s under false advertising as secure when Intel knew they were not. Here are some of the largest fines dished out by the EU 2) The Internet has evolved from Web 1.0 to 2.0. Consumers are increasing their online presence each year. This reduces the clout that Intel can wield over the market as AMD can more easily sell to consumers through smaller Internet based companies. 3) Traditional distributors (HP, Dell, Lenovo, etc.) are struggling. All of these companies have had recent issues with declining revenue due to Internet competition, and ARM competition. These companies are struggling for sales and this reduces the clout that Intel has over them, as Intel is no longer able to ensure their future. It no longer pays to be in the club. These points are summarized in the graph below, from Statista, which shows “ODM Direct” sales and “other sales” increasing their market share from 2009 to Q3 2017. 4) AMD spun off Global Foundries as a separate company. AMD has a fabrication agreement with Global Foundries, but is also free to fabricate at another foundry such as TSMC, where AMD has recently announced they will be printing Vega at 7nm. 5) Global Foundries developed the capability to fabricate at 16nm, 14nm, and 12nm alongside Samsung, and IBM, and bought the process from IBM to fabricate at 7nm. These three companies have been cooperating to develop new fabrication nodes. 6) The computer market has grown much larger since the mid-90’s – 2006 when AMD last had a significant tangible advantage over Intel, as computer sales rose steadily until 2011 before starting a slow decline, see Statista graph below. The decline corresponds directly to the loss of competition in the marketplace between AMD and Intel, when AMD released the Bulldozer CPU in 2011. Tablets also became available starting in 2010 and contributed to the fall in computer sales which started falling in 2012. It’s important to note that computer shipments did not fall in 2017, they remained static, and AMD’s GPU market share rose in Q4 2017 at the expense of Nvidia and Intel. 7) In terms of fabrication, AMD has access to 7nm on Global Foundries as well as through TSMC. It’s unlikely that AMD will experience CPU fabrication problems in the future. This is something of a reversal of fortunes as Intel is now experiencing issues with its 10nm fabrication facilities which are behind schedule by more than 2 years, and maybe longer. It would be costly for Intel to use another foundry to print their CPU’s due to the overhead that their current foundries have on their bottom line. If Intel is unable to get the 10nm process working, they’re going to have difficulty competing with AMD. AMD: Current market conditions In 2011 AMD released its Bulldozer line of CPU’s to poor reviews and was relegated to selling on the discount market where sales margins are low. Since that time AMD’s profits have been largely determined by the performance of its GPU and Semi-Custom business. Analysts have become accustomed to looking at AMD’s revenue from a GPU perspective, which isn’t currently being seen in a positive light due to the relation between AMD GPU’s and cryptocurrency mining. The market views cryptocurrency as further risk to AMD. When Bitcoin was introduced it was also mined with GPU’s. When the currency switched to ASIC circuits (a basic inexpensive and simple circuit) for increased profitability (ASIC’s are cheaper because they’re simple), the GPU’s purchased for mining were resold on the market and ended up competing with and hurting new AMD GPU sales. There is also perceived risk to AMD from Nvidia which has favorable reviews for its Pascal GPU offerings. While AMD has been selling GPU’s they haven’t increased GPU supply due to cryptocurrency demand, while Nvidia has. This resulted in a very high cost for AMD GPU’s relative to Nvidia’s. There are strategic reasons for AMD’s current position: 1) While the AMD GPU’s are profitable and greatly desired for cryptocurrency mining, AMD’s market access is through 3rd party resellers whom enjoy the revenue from marked-up GPU sales. AMD most likely makes lower margins on GPU sales relative to the Zen CPU sales due to higher fabrication costs associated with the fabrication of larger size dies and the corresponding lower yield. For reference I’ve included the size of AMD’s and Nvidia’s GPU’s as well as AMD’s Ryzen CPU and Intel’s Coffee lake 8th generation CPU. This suggests that if AMD had to pick and choose between products, they’d focus on Zen due higher yield and revenue from sales and an increase in margin. 2) If AMD maintained historical levels of GPU production in the face of cryptocurrency demand, while increasing production for Zen products, they would maximize potential income for highest margin products (EPYC), while reducing future vulnerability to second-hand GPU sales being resold on the market. 3) AMD was burned in the past from second hand GPU’s and want to avoid repeating that experience. AMD stated several times that the cryptocurrency boom was not factored into forward looking statements, meaning they haven’t produced more GPU’s to expect more GPU sales. In contrast, Nvidia increased its production of GPU’s due to cryptocurrency demand, as AMD did in the past. Since their Pascal GPU has entered its 2nd year on the market and is capable of running video games for years to come (1080p and 4k gaming), Nvidia will be entering a position where they will be competing directly with older GPU’s used for mining, that are as capable as the cards Nvidia is currently selling. Second-hand GPU’s from mining are known to function very well, with only a need to replace the fan. This is because semiconductors work best in a steady state, as opposed to being turned on and off, so it will endure less wear when used 24/7. The market is also pessimistic regarding AMD’s P/E ratio. The market is accustomed to evaluating stocks using the P/E ratio. This statistical test is not actually accurate in evaluating new companies, or companies going into or coming out of bankruptcy. It is more accurate in evaluating companies that have a consistent business operating trend over time. “Similarly, a company with very low earnings now may command a very high P/E ratio even though it isn’t necessarily overvalued. The company may have just IPO’d and growth expectations are very high, or expectations remain high since the company dominates the technology in its space.” P/E Ratio: Problems With The P/E I regard the pessimism surrounding AMD stock due to GPU’s and past history as a positive trait, because the threat is minor. While AMD is experiencing competitive problems with its GPU’s in gaming AMD holds an advantage in Blockchain processing which stands to be a larger and more lucrative market. I also believe that AMD’s progress with Zen, particularly with EPYC and the recent Meltdown related security and performance issues with all Intel CPU offerings far outweigh any GPU turbulence. This turns the pessimism surrounding AMD regarding its GPU’s into a stock benefit. 1) A pessimistic group prevents the stock from becoming a bubble. -It provides a counter argument against hype relating to product launches that are not proven by earnings. Which is unfortunately a historical trend for AMD as they have had difficulty selling server CPU’s, and consumer CPU’s in the past due to market interference by Intel. 2) It creates predictable daily, weekly, monthly, quarterly fluctuations in the stock price that can be used, to generate income. 3) Due to recent product launches and market conditions (Zen architecture advantage, 12nm node launching, Meltdown performance flaw affecting all Intel CPU’s, Intel’s problems with 10nm) and the fact that AMD is once again selling a competitive product, AMD is making more money each quarter. Therefore the base price of AMD’s stock will rise with earnings, as we’re seeing. This is also a form of investment security, where perceived losses are returned over time, due to a stock that is in a long-term upward trajectory due to new products reaching a responsive market. 4) AMD remains a cheap stock. While it’s volatile it’s stuck in a long-term upward trend due to market conditions and new product launches. An investor can buy more stock (with a limited budget) to maximize earnings. This is advantage also means that the stock is more easily manipulated, as seen during the Q3 2017 ER. 5) The pessimism is unfounded. The cryptocurrency craze hasn’t died, it increased – fell – and recovered. The second hand market did not see an influx of mining GPU’s as mining remains profitable. 6) Blockchain is an emerging market, that will eclipse the gaming market in size due to the wide breath of applications across various industries. Vega is a highly desired product for Blockchain applications as AMD has retained a processing and performance advantage over Nvidia. There are more and rapidly growing applications for Blockchain every day, all (or most) of which will require GPU’s. For instance Microsoft, The Golem supercomputer, IBM, HP, Oracle, Red Hat, and others. Long-term upwards trend AMD is at the beginning of a long-term upward trend supported by a comprehensive and competitive product portfolio that is still being delivered to the market, AMD referred to this as product ramping. AMD’s most effective products with Zen is EPYC, and the Raven Ridge APU. EPYC entered the market in mid-December and was completely sold out by mid-January, but has since been restocked. Intel remains uncompetitive in that industry as their CPU offerings are retarded by a 40% performance flaw due to Meltdown patches. Server CPU sales command the highest margins for both Intel and AMD. The AMD Raven Ridge APU was recently released to excellent reviews. The APU is significant due to high GPU prices driven buy cryptocurrency, and the fact that the APU is a CPU/GPU hybrid which has the performance to play games available today at 1080p. The APU also supports the Vulcan API, which can call upon multiple GPU’s to increase performance, so a system can be upgraded with an AMD or Nvidia GPU that supports Vulcan API at a later date for increased performance for those games or workloads that been programmed to support it. Or the APU can be replaced when the prices of GPU’s fall. AMD also stands to benefit as Intel confirmed that their new 10 nm fabrication node is behind in technical capability relative to the Samsung, TSMC, and Global Foundries 7 nm fabrication process. This brings into questions Intel’s competitiveness in 2019 and beyond.

AMD’s growing CPU advantage over Intel About AMD’s Zen Zen is a technical breakthrough in CPU architecture because it’s a modular design and because it is a small CPU while providing similar or better performance than the Intel competition. Since Zen was released in March 2017, we’ve seen AMD go from 18% CPU market share in the OEM consumer desktops to essentially 50% market share, this was also supported by comments from Lisa Su during the Q3 2017 ER call, by MindFactory.de, and by Amazon sales of CPU’s. We also saw AMD increase its market share of total desktop CPU’s. We also started seeing market share flux between AMD and Intel as new CPU’s are released. Zen is a technical breakthrough supported by a few general guidelines relating to electronics. This provides AMD with an across the board CPU market advantage over Intel for every CPU market addressed. 1) The larger the CPU the lower the yield. - Zen architecture that makes up Ryzen, Threadripper, and EPYC is smaller (44 mm2 compared to 151 mm2 for Coffee Lake). A larger CPU means fewer CPU’s made during fabrication per wafer. AMD will have roughly 3x the fabrication yield for each Zen printed compared to each Coffee Lake printed, therefore each CPU has a much lower cost of manufacturing. 2) The larger the CPU the harder it is to fabricate without errors. - The chance that a CPU will be perfectly fabricated falls exponentially with increasing surface area. Intel will have fewer high quality CPU’s printed compared to AMD. This means that AMD will make a higher margin on each CPU sold. AMD’s supply of perfect printed Ryzen’s (1800X) are so high that the company had to give them away at a reduced cost in order to meet supply demands for the cheaper Ryzen 5 1600X. If you bought a 1600X in August/September, you probably ended up with an 1800X. 3) Larger CPU’s are harder to fabricate without errors on smaller nodes. -The technical capability to fabricate CPU’s at smaller nodes becomes more difficult due to the higher precision that is required to fabricate at a smaller node, and due to the corresponding increase in errors. “A second reason for the slowdown is that it’s simply getting harder to design, inspect and test chips at advanced nodes. Physical effects such as heat, electrostatic discharge and electromagnetic interference are more pronounced at 7nm than at 28nm. It also takes more power to drive signals through skinny wires, and circuits are more sensitive to test and inspection, as well as to thermal migration across a chip. All of that needs to be accounted for and simulated using multi-physics simulation, emulation and prototyping.“ Is 7nm The Last Major Node? “Simply put, the first generation of 10nm requires small processors to ensure high yields. Intel seems to be putting the smaller die sizes (i.e. anything under 15W for a laptop) into the 10nm Cannon Lake bucket, while the larger 35W+ chips will be on 14++ Coffee Lake, a tried and tested sub-node for larger CPUs. While the desktop sits on 14++ for a bit longer, it gives time for Intel to further develop their 10nm fabrication abilities, leading to their 10+ process for larger chips by working their other large chip segments (FPGA, MIC) first.” There are plenty of steps where errors can be created within a fabricated CPU. This is most likely the culprit behind Intel’s inability to launch its 10nm fabrication process. They’re simply unable to print such a large CPU on such a small node with high enough yields to make the process competitive. Intel thought they were ahead of the competition with respect to printing large CPU’s on a small node, until AMD avoided the issue completely by designing a smaller modular CPU. Intel avoided any mention of its 10nm node during its Q4 2017 ER, which I interpret as bad news for Intel shareholders. If you have nothing good to say, then you don’t say anything. Intel having nothing to say about something that is fundamentally critical to its success as a company can’t be good. Intel is on track however to deliver hybrid CPU’s where some small components are printed on 10nm. It’s recently also come to light that Intel’s 10nm node is less competitive than the Global Foundries, Samsung, and TSMC 7nm nodes, which means that Intel is now firmly behind in CPU fabrication. 4) AMD Zen is a new architecture built from the ground up. Intel’s CPU’s are built on-top of older architecture developed with 30-yr old strategies, some of which we’ve recently discovered are flawed. This resulted in the Meltdown flaw, the Spectre flaws, and also includes the ME, and AMT bugs in Intel CPU’s. While AMD is still affected by Spectre, AMD has only ever acknowledged that they’re completely susceptible to Spectre 1, as AMD considers Spectre 2 to be difficult to exploit on an AMD Zen CPU. “It is much more difficult on all AMD CPUs, because BTB entries are not aliased - the attacker must know (and be able to execute arbitrary code at) the exact address of the targeted branch instruction.” Technical Analysis of Spectre & Meltdown * Amd Further reading Spectre and Meltdown: Linux creator Linus Torvalds criticises Intel's 'garbage' patches | ZDNet FYI: Processor bugs are everywhere - just ask Intel and AMD Meltdown and Spectre: Good news for AMD users, (more) bad news for Intel Cybersecurity agency: The only sure defense against huge chip flaw is a new chip Kernel-memory-leaking Intel processor design flaw forces Linux, Windows redesign Take-Away • AMD Zen enjoys a CPU fabrication yield advantage over Intel • AMD Zen enjoys higher yield of high quality CPU’s • Intel’s CPU’s are affected with 40% performance drop due to Meltdown flaw that affect server CPU sales.

Conclusion While in the past Intel interfered with AMD's ability to bring it's products to market, the market has changed. The internet has grown significantly and is now a large market that dominates when in computer sales. It's questionable if Intel still has the influence to affect this new market, and doing so would most certainly result in fines and further bad press. AMD's foundry problems were turned into an advantage over Intel. AMD's more recent past was heavily influenced by the failure of the Bulldozer line of CPU's that dragged on AMD's bottom line from 2011 to 2017. AMD's Zen line of CPU's is a breakthrough that exploits an alternative, superior strategy, in chip design which results in a smaller CPU. A smaller CPU enjoys compounded yield and quality advantages over Intel's CPU architecture. Intel's lead in CPU performance will at the very least be challenged and will more likely come to an end in 2018, until they release a redesigned CPU. I previously targeted AMD to be worth $20 by the end of Q4 2017 ER. This was based on the speed that Intel was able to get products to market, in comparison AMD is much slower. I believe the stock should be there, but the GPU related story was prominent due to cryptocurrency craze. Financial analysts need more time to catch on to what’s happening with AMD, they need an ER that is driven by CPU sales. I believe that the Q1 2018 is the ER to do that. AMD had EPYC stock in stores when the Meltdown and Spectre flaws hit the news. These CPU’s were sold out by mid-January and are large margin sales. There are many variables at play within the market, however barring any disruptions I’d expect that AMD will be worth $20 at some point in 2018 due these market drivers. If AMD sold enough EPYC CPU’s due to Intel’s ongoing CPU security problems, then it may occur following the ER in Q1 2018. However, if anything is customary with AMD, it’s that these things always take longer than expected.
Denne meldingen dumpet nettopp inn som svar på en annonse jeg har liggende ute på Finn.no:
bmiklozek har sendt deg en melding på FINN. Check out cryptotech.no read the whitepaper and here are some specs. -67% reduction in of logic circuits, can place more active circuitry on the same die size -80% less power consumption and 1/3 the price of manufacturing cost -10x faster than current chip designs (400Gh per 3 x 3mm chip) -Liquid cooled for maximum efficiency -Powered by renewable hydroelectric energy in Norway with near ZERO emissions What is crazy about this is that it is on the 22nm SOI process. This is cheap and readily available to manufacture unlike the 7nm. However, when the move to the 7nm becomes mainstream 16nm should free up more. It is going to be awesome to see the efficiency on the 16nm, 12nm or lower process. Even on a 16nm could potentially produce 800Gh per chip. In addition, this technology will solve the energy consumption problems that Bitcoin creates through mining and transactions.
Whatsminer M10s is 16nm ASIC miner for SHA-256 Algorithm, it can mine Bitcoin or Bitcoin Cash with a hashrate of 55th/s (+-5%). Power consumption is 3500w (+-10%). Power Supply Unit: Power P5, 2500w, 93% efficiency 240V 220V 120V (included) Further, the company’s website sells a mobile bitcoin mining unit called the ‘Blockbox,’ and it still sells custom 16nm semiconductor chips. The company hasn’t shown any signs of designing The M20S version uses TSMC-created 12nm semiconductors. Pangolin was still using 28nm and 16nm chips. Plug your own hardware into the world’s most profitable Bitcoin mining pool or get bitcoin is all about competition. if you can make a better coin than bitcoin - go ahead (speaking hypothetically). everyone is free to develop a microchip that is more efficient at mining. the CPU industry is very limited as well, there are not a ton of companies out there that produce state-of-the-art CPUs. yet - nobody complains about this. its all about competition. if someone comes up with News.Bitcoin.com covered the rising hashrates per unit from devices sold in 2018 and the hashrate increase in 2019 has been exponential. For instance, in 2017-2018 many mining rigs shifted from the 16nm semiconductor standard to the lower 12nm, 10nm and 7nm processes.
