What kind of graphics card does bitcoin mine use
Why use graphics card to mine
compared with CPU, GPU is used for general purpose calculation. So it can stack hundreds of stream processors awesome. Each stream processor is like a small CPU. Although its ability to run complex programs is far from the power of CPU, it can not support many processors, so the actual performance, especially the single precision floating point performance is much stronger than that of CPU. p> However, as we have mentioned before, a card is very suitable for general computing such as virtual currency because it has many stream processors, and the speed of obtaining specific solutions is much higher than that of N card. Therefore, many miners rush to buy a card to calculate virtual currency for profit
of course, with NVIDIA's Pascal graphics card, n card's ability in mining virtual currency is not as different as a card before. So in the current situation that a card is generally out of stock, those mid-range N cards have become the second choice for miners
What are the disadvantages of mine cardfinally, I want to talk about why we can't choose mine card when we are shopping for second-hand cards. Because the miners are mining bitcoin, the most important thing is to seek profits. Therefore, the graphics card they use is running and calculating all the time, and its strength is far greater than that of daily game applications. In other words, running such a calculation for one day is equivalent to running a graphics card for one month
in addition, the places where virtual currency is mined are mostly the places where multiple graphics cards gather. Thousands of graphics cards are constantly calculating in a room, and their heat is also quite huge. Miners can not choose the chassis with good heat dissipation conditions like ordinary consumers, so that the heat can be released smoothly. In this way, the graphics cards can still operate for 7 * 24 hours under high temperature conditions, It also deepens its aging degree
the result of doing so is that the graphics cards used for mining are lost prematurely. If you buy these graphics cards, the result will be unstable operation, restart and other things will continue to happen
moreover, at present, manufacturers also have strict requirements on mine cards, such as banning second-hand sales and shortening the shelf life. If users buy these mine card graphics cards, future maintenance will also be a big challenge
hd7990 is the current king. It is said that the electricity charge for mining each bitcoin is 130-140 yuan. In other words, a monster card like hd7990 needs to work for about 20 days to get a bitcoin. A bitcoin may consume 300 watts of power, not counting the loss of computers
in addition to the graphics card, other hardware of the mining platform will also consume electricity. CPU / motherboard, memory, hard disk, including the power supply for the whole machine, will still need electricity because there is no 100% conversion rate. Compared with the display that can be turned off in pure standby, they have to intervene
the faster the graphics card mining speed is, the less unnecessary power consumption will be consumed for each bitcoin acquisition. In this case, the graphics card with fast computing speed often has more advantages. If a multi card platform is established, the net profit per unit time will be higher
the lower the performance of the card, the more power it consumes on average
in a word! Investment must be cautious.
depending on your budget, it is recommended to buy high-end graphics card ~
but now the AMD graphics cards in various shopping malls are almost out of stock, and it is difficult to buy them
