Amdcpu mining
while NVIDIA graphics card provides less computing resources, mainly through software optimization to achieve game acceleration. In addition, game n card simplifies some moles used in scientific computing (mining just belongs to this kind of Computing),
therefore, in the face of mining, which is a simple and high load operation, the N card with weak body will not work
for now, the design between AMD and NVIDIA is more and more similar. The a-card part absorbs the advantages of serial and branch judgment of n-card, and the n-card part also adopts the simple violence stack design of a-card. So who has the advantage is a mathematical proportion problem, whose graphics card is more accurate to the proportion planning of game resources, whose performance is better
so mining depends on the efficiency of the algorithm. A card is really good at an algorithm called SHA-256, which was used in violent decoding before (so a card also has a good performance in violent decoding)
unfortunately, in order to rece the power consumption, n card has actually simplified some scientific computing moles. As we said downstairs, the CPU is good at the work of branch judgment. N card no longer relies on itself, instead, it has been deleted, leaving this part of the work to the CPU to the processor, so the general computing performance is weaker than a card. As for the advantages of N card in the field of professional card for a card mentioned by some people, it mainly depends on the early investment and construction in the application of software in the past, that is, the early optimization is still in place, and now the old customers are still eating well
it is true that Tianhe first used 4870 as accelerator card, but there may be a mistake, that is, it was not NVIDIA's Tesla that was used by new Tianhe, but Titan, another supercomputer, which was not entirely Tesla processor, but also AMD's Haolong processor for collaborative computing. In fact, tianhe-2 uses Intel's Xeon Phi processor, neither amd nor NVIDIA.

4096 stream processors and high-speed HBM video memory can't match the number of GTX
980ti
2816 stream processors, but the pure computing power is still very strong. Mining is easier to achieve higher core utilization, while graphics rendering is very difficult, which depends heavily on the graphics architecture. Of course, GPU mining has long been out of date. They are all ASIC circuits with high performance and low power consumption
the above is the content. It answers your question very well
in fact, n card has greatly enhanced the mining efficiency in the Maxwell architecture, not inferior to a card. But the Maxwell architecture came out too late. When the earliest Maxwell architecture graphics card, such as gtx750ti / 750, came into the market (early 2014), the mainstream currencies could not dig out anything with graphics cards (all mining machines). Therefore, few people use n-card mining.
Mine card refers to the graphics card used by bitcoin mining machine, mostly amd graphics card
mine disaster refers to the decline in the price of bitcoin and the sale of second-hand mine cards
bitcoin mining machine graphics card long-term high load operation, graphics card service life will be reced accordingly, so the price will be cheaper
extended data:
bitcoin mining machine is a computer used to earn bitcoin. This kind of computer generally has professional mining chips, and mostly works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server
bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high
