Gtx1080sha256 calculation force
eth is only 32mh / s, 1070 has 40mh / s. Many people say that 1080ti can't pull up the computing power because of the high delay of gddr5x video memory. As expected, it's better to mine with a card. People on the Internet say that 480 can have 65mh / S computing power
Zec, 724sol / s, nearly three 1060 3G, the total price is more expensive than three 1060 2K soft coins. However, compared with the short supply a-card rx4808g, the price of three cards is less than 5K, and the computing power is 900 + sol / s, but it's useless if there is a price but no market
it's too wasteful to use this card for mining. It's just for fun and can't afford to hurt.
Amd graphics card is recommended for bitcoin, n card is not suitable
moreover, one video card can't dig one coin a week, so it needs several amd video cards to dig together, and some even use mining machines. At present, mining on the computer platform is unprofitable for ordinary users unless they are professional players
at present, the popular cards for deep learning are rtx2080ti and rtx2070 (multi-channel), and it is not easy to buy more than one of them when gtx1080ti is delisted Second hand another)
* for the deep learning of CUDA platform, the graphics card mainly focuses on: single precision floating-point operation, video memory, tensor core (Turing architecture and volt architecture, RTX series and Titan V)
* in terms of the main stability and some special functions of Tesla, double precision (currently this deep learning is less used), single precision and half precision floating-point operation have little advantage, It's expensive (if you want to surpass gtx1080ti, you need tens of thousands of Tesla V100)
when building bitcoin, Nakamoto wants bitcoin to be a decentralized currency, not only for use and trading, but also for mining. But it backfired. With the increasing value of cryptocurrency such as bitcoin, mining has become an instry. The competition is more and more fierce, and the pursuit of mining computing power is higher and higher. Therefore, from ordinary computer mining, ASIC mining machine and GPU mining machine have evolved
the algorithm of ASIC mining machine is almost sha256, while the algorithm of GPU mining is different. For example, the algorithm of BTG is equihash, and the algorithm of BCD is optimized x13. Although it is not absolute, it can be simply considered that the currency of sha256 algorithm is generally mined by ASIC mining machine. Other algorithms are basically using GPU miner. There are also exceptions. Scrypt's Leyte coin used to be mined by GPU miner, but later scrypt's algorithm was also conquered by ASIC chips, such as ant miner L3 +, which is the ASIC miner used to dig Leyte coin
ASIC miner refers to the miner that uses ASIC chip as the core of computing power. ASIC is the abbreviation of application specific integrated circuit, which is a kind of electronic circuit (chip) specially designed for a specific purpose. Some mining machinery factories have designed ASIC chips specially for computing the sha256 algorithm of bitcoin, and the mining machinery using them is ASIC mining machinery. Because ASIC chip is only built for specific computing, its efficiency can be much higher than that of CPU. For example, the current mainstream ant miner S9 is ASIC miner, which uses 189 ASIC chips, the computing power reaches 13.5th/s, and the power consumption is only 1350W. As a comparison, the computing power of gtx1080ti, the flagship computer graphics card, will not exceed 60mh / s even if it is optimized well. The difference is tens of thousands of times
GPU miner refers to the miner that uses GPU graphics card as the core of computing power. Cryptocurrencies such as Ethereum, bitcoin and diamond use graphics algorithms, so the speed of computing with graphics card will be the highest. Compared with ASIC miner, GPU miner is more well-known, because it is a computer with enhanced graphics card configurationthe purpose of GPU miner is to make money, so we should pursue the power consumption ratio and maximum profit, so we should pay attention to the cost performance. Generally, the medium and high-end positioning graphics cards, such as AMD rx560 and rx570, have high power consumption ratio, which is a good choice for GPU miner. While flagship cards such as gtx1080ti and AMD vega64 have the strongest single card performance, they are not cost-effective in terms of price and power consumption
in addition, the ASIC miner also has some exotic procts, such as the USB miner of burning cat, which is slightly larger than the U disk, and the power consumption is only 2.25w, which is the smallest bitcoin miner at present
< / blockquote >the above quoted digcoin.com - "Introction to mining machinery classification" has many professional terms. I hope it can help you, thank you
home computer can't even earn back the cost of digging bitcoin
at present, the home computers all dig up the Leyte coin, because there is no special Leyte coin miner, so it should be able to earn money
hope to adopt.
don't think too much about it. It's almost enough to play games with this card.
With the increasing performance of display chip, its data processing ability becomes stronger, which makes the requirements of data transmission capacity and transmission rate become higher, and the requirements of graphics card for graphics memory are also higher. At present, most of the graphics cards use gddr2-5 generation of graphics memory
nowadays, the performance of graphics card is getting stronger and stronger, which can't ignore the fact that the development speed of display chip is fast, but the frequency, bit width and bandwidth of graphics memory also restrict the overall performance of graphics card. The advanced display memory can make the display chip work with all its strength and make the output picture smoother
the higher the frequency of video memory, the faster the data can be recorded and read on the video memory. The frequency of video memory provided by different video memories also varies greatly. The early video memories include 133MHz, 166MHz, 400MHz, 500MHz, 600MHz, 650MHz, etc
at present, there are 800MHz, 1200MHz, 1600MHZ, 2200MHz and even higher middle end procts. The method to calculate the equivalent frequency is to take the frequency of video memory * generation. For example, if the frequency of gddr5 video memory is 2000MHz, the equivalent frequency of 8000MHz can be obtained from 2000 * 4
extended data:
working principle
the working principle of the graphics card is: before the graphics card starts to work (graphics rendering modeling), it usually transfers the required material and texture data to the video memory
Whenstarts to work (modeling and rendering), these data are transmitted through AGP bus, and the display chip will extract the data stored in the display memory through AGP bus. In addition to modeling and rendering data, there are a lot of vertex data and work instruction flow to be exchanged, and these data are converted into analog signals and output to the display terminal through RAMDAC, In the end, it's the image we see
With the improvement of the performance of the display chip, the data processing ability of the display chip becomes stronger and stronger, which makes the data transmission capacity and transmission rate of the video memory more and more demanding, and the video card also has higher requirements for the video memory. At this time, the exchange capacity and speed of the video memory are very important for the performance of the core of the video card, and how to effectively improve the performance of the video memory has become the key to improve the performance of the whole display card
