What kind of graphics card does bitcoin miner use

1.

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 card

finally, 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

Mining needs high-end graphics card, mining equipment is the first to eliminate NV graphics card. Mining must be done with graphics cards. The overall structure of mining equipment and ordinary PC machine is different is the number of graphics cards. You can install four or eight through pic extension

after expansion, an expansion shelf needs to be made. To fix the graphics card and other equipment, we need to get some fans on the shelf to cool the graphics card

CPU is not very important. But not lower than i5< br />

3. Before the appearance of mining machine in 2012, the era of mining with graphics card used a card, because mining is to split hash operation into multiple sub operations. At that time, a card can complete one operation with one instruction set, while n card needs three instruction sets to complete one operation. Therefore, the actual operation efficiency of a card is more than twice that of N card, which is close to three times

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.

5. Bitcoin is a member of the virtual currency. The data is calculated by a specific algorithm, and the total number of data is fixed. Therefore, bitcoin is less and less g, and it is more and more difficult to dig. Recently, bitcoin's rise is quite high, which has spawned a group of new miners to enter the pit. It can only be said that they are waiting for the mine disaster. Amd graphics card is generally preferred in mining, because in recent generations, n card tends to simplify the basic floating-point operation and improve the utilization rate of the architecture to the core, while a card has always liked the heap stream processor with crazy heap parameters, just what mining needs is the basic double precision floating-point operation ability, so a card is generally preferred in mining.

6. Mining? Of course, the more SP, the better. But we should also pay attention to cost performance, otherwise we can't recover the cost of 6970
