Video card (graphics card) full name display interface card, also known as display adapter, is the most basic configuration of computer, one of the most important accessories. As an important part of the computer host, the graphics card is the equipment of digital to analog signal conversion, and it undertakes the task of output display graphics
the graphics card is connected to the main board of the computer, which converts the digital signal of the computer into an analog signal for the display. At the same time, the graphics card still has the ability of image processing, which can help the CPU work and improve the overall running speed. For those engaged in professional graphic design, graphics card is very important. Civil and military graphics chip suppliers mainly include amd (ultra micro semiconctor) and NVIDIA (NVIDIA). Today's TOP500 computer, including graphics card computing core. In scientific computing, graphics card is called display accelerator
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.
If you are really interested in lending me ten yuan, let's go to Alibaba cloud to try
the packer of the transaction is the miner, and the income from the miner's packaged transaction is bitcoin
miner's income consists of two parts:
1. Service charge is required for package transaction (users pay part of bitcoin)
2. A reward (bitcoin) will be automatically generated for each block generated
It depends on the computing power of GPU and CPU instead of the computing speed. Although there is no big difference, because the computing principle of graphics card is different from CPU, and mining needs distributed computing. In this kind of computing, graphics card GPU is better than CPU
for example, the single precision of i54590 is only 440, and the double precision is 220 (measured). The single precision computing power of an rx470 is more than 10 times that of i54590. The computing power is very strong. So it's faster to use the graphics card, and the power consumption is also low. If you want to use the CPU to achieve 4000 computing speed, you need more than 10 CPUs, and the power consumption is at least 700W. The motherboard memory needs money. Graphics card just need to expand the slot.
