Does the miner use public version graphics card
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
for mining, all mining machines do not shut down for several months. And the graphics card is always full of work, there is no time to rest
some of them are still used in overclocking mode, which is much more intensive than the personal home graphics card used for several years.
needs higher computing power, not the performance of graphics card. AMD and NVIDIA have the same price of graphics card, amd has higher computing power, so mining machine uses this kind of graphics card more, I hope it can help you
Mining is a work that needs a lot of computing power to support. The reason why we use the graphics card mining machine is that the graphics card is easier to carry out a lot of repeated calculations than the CPU, so the general mining machine of the graphics card selects the graphics card mining machine
but mining also need to find a useful mining software, I have been using ha Yu miner mining, easy to use, high income< br />
1g version is the most popular. This model can well balance the mining speed and price
in other words, there are a lot of "mining machine graphics cards" on Taobao, because these graphics cards use less materials under the same core and basically unchanged hash speed, such as recing video memory to improve the performance price ratio (the size of video memory has little to do with the mining speed), which can shorten the time to recover the cost
in short, the graphics card of mining machine is the core of common high-end graphics card + the workmanship of low-end graphics card, or some cheap medium and high-end public graphics card.
mining is to split hash operation into several sub operations. 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 cards, such as gtx750ti / 750, came into the market, the mainstream currencies could not dig out anything with graphics cards. Therefore, few people use n-card mining.
1. The provincial characteristics of the blockchain, once included in the block, are irreversible and can not be tampered with, and the information is true and effective, but there is only one case that is false, that is, the information written in the first attempt is false, resulting in the false information stored in the block
2, Basically, it's the application side of the technology
