7Nm miner

1. This child is not very normal, so he is suggested to be sent to a doctor for treatment.
serious answer: are these two gods guilty of buying mining machines? They are all against bitcoin. Do you still want them to buy mining machines?

2. In my opinion, if it reaches 10nm, the movement of the electron will have a great impact on the normal operation, which will greatly affect the yield of the proct. As far as I know, there is no good process to solve this kind of problem. Therefore, in the short run, it is better to consider expanding to three dimensions than to increase the plane density. It may be a practical method to forget the multi stack scheme proposed by which company in the front-end time.

3. The picture is still too small to see clearly! Send a bigger picture

TSMC has proced many 7Nm chips in advance e to policy restrictions. These chips have a great impact on the mobile phone market, because TSMC is indeed a very cutting-edge and influential enterprise in the field of chip OEM manufacturing, although there will be 5nm or even higher precision chips in the future, But it is destined to be a long time in the future, with the chip of about 7 nanometers

Although TSMC is a chip foundry enterprise, its core technology and complex holding structure can ensure its market share in the future. Qualcomm Apple may compete with TSMC, but the survival of the most fundamental one is still not a problem, The profit margin may be affected to some extent, but there is no problem about the future

5. Mine card can't be detected, because mine card is ordinary graphics card. It's just used for mining
the special mine card has no video output function, it's just a kind of board responsible for calculation. Strictly speaking, it's not a graphics card, but a calculation card
if you buy a second-hand card used for mining, you can only feel it in the process of using it, the failure rate of the card is relatively high, and it is easy to have symptoms such as blue screen and flower screen.

6. Of course, digital currency has a future. The future of digital currency is very broad
bitcoin, wikilink, bitcoin cash and Ethereum are all digital currencies. The people's Bank of China started to study digital currency three years ago and is now cooperating with the instry to develop distributed ledger. The central bank has put the issue of digital currency on the agenda.

7. The increment of computing power is the increase of computing speed
computing power: in short, it is a quantitative indicator of the computing speed of your mining machine. For example, 1t computing power is the 12th power of 10 in 1s. If the 12th power of this 10 can work out the results that meet the conditions, it will be g. If not, it can be said that it is in vain

in the face of the exponential increase of data, computing power is the biggest demand for enterprises and institutions, and improving computing power requires higher performance CPU and GPU
last time, AMD processor pushed the computing power of HPC to billion times, but now AMD with epyc processor pushes the computing power of supercomputing to 10 billion times again. AMD's two E-class supercomputer systems, frontier and El Capitan, are scheled to be delivered in 2021 and 2023, respectively. They will achieve the expected processing performance of more than 150 exaflops (10 billion times) and 2 exaflops, respectively, and are expected to become the fastest supercomputer in the world
it is a big challenge for any manufacturer to improve the computing power in a short time. How did amd make such great progress? Let's start in 2017
in 2017, amd adopted a new Zen architecture, launched the first generation epyc processor, and dramatically increased the number of single processor cores to 32 cores. Two years later, the introction of the second generation epyc processor not only upgraded the architecture to zen2, but also reced the process technology from 14nm to 7Nm, which improved the IPC performance by 15%
compared with the Zen architecture, the new zen2 architecture optimizes the L1 instruction cache, doubles the operation cache capacity and floating point unit data bit width, and doubles the L3 cache to 16MB. The 64 core epyc processor easily has 128MB L3 cache. What's more, the second generation epyc adopts 7Nm process, which effectively reces the power consumption. Under 225W TDP, the number of cores can be increased to 64 cores, which makes its performance significantly improved
in the past year, the second generation of AMD epyc processor has achieved more than 140 world records, covering cloud computing, virtualization, high-performance computing, big data analysis and other fields, and also with strong performance to meet the increasing demand of enterprises or institutions for computing power
therefore, relying on the leading performance of epyc processor and ultra-high power consumption ratio, amd has not only won more market share and broken many world records, but also expanded its ecosystem.

When it comes to the rise of smart phones in China, many people are talking about it with relish. Five or six years ago, it was basically synonymous with Shanzhai. Today, it occupies more than 50% of the global market and more than 80% of China's market, and its share is still expanding, which makes people not agree with it

but at the same time, we found that although domestic mobile phones are so strong and the level of Shanzhai is so high, other flagship mobile phones, except Huawei Qilin, have been using Qualcomm chips. Many people wonder why China's proction level of smart phones is so high, but it can't proce a high-end chip. Why can't we Shanzhai

The chip is a kind of technology that can not be copied. If you give a chip, you can the design, but not the manufacturing. After all, this technology needs time, accumulation, patent, investment, talent, equipment and so on

and what China is good at most is Shanzhai; Replicable & quot; The rapid development of smart phones can also explain why the chips have not been copied by Chinese Shanzhai
