Why use a video card to dig virtual currency? You’ll understand after reading it
In recent months, including a variety of virtual currency bitcoin, bitcoin is popular, especially the more so, the price even more than 10000 yuan, the price can be said to take a similar rocket. The result is that the AMD cards are miners robbed, 400 line and 500 line cards on the market are basically disappeared.
So what is the virtual currency? Why use the graphics card, especially the AMD graphics card to calculate? IT’s home here to do a small popular science, so that we will see later bitcoin and other virtual currency news will no longer be confused.
What is bitcoin (virtual currency)?
To answer these questions, we first need to know what bitcoin is The concept of bitcoin (BitCoin) was originally proposed by Zhong Cong in 2009. According to the idea of China, we design and publish open source software and build P2P network on it. Bitcoin is a digital currency in the form of P2P. Peer to peer transmission means a centralized payment system.
From the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a complex algorithm. A special solution is a set of solutions that can be obtained by an infinite set of equations (in fact, a finite number of bitcoins). And every particular solution can solve the equation and is unique.
Why use graphics mining?
Compared to the complex operations of CPU, the GPU used by graphics cards is general-purpose computing. It can be stacked hundreds of processors, each stream processor is like small CPU, although its ability to run complex applications far from CPU to awesome, but JiaBuZhu stream processor, so the actual performance especially the single precision floating point performance is much better than CPU.
– chart graphics, the stream processor is dense
Including digging bitcoin within the action we can think is the use of graphics in constantly general calculation, and the computational complexity is relatively low and quite repetitive, stream processor is suitable for the use of graphics algorithm. It’s like solving equations, video cards are 2000 middle school students, and CPU is 8 math doctor. Although Dr math’s knowledge of mathematics is far superior to that of middle school students, the speed of the medium equations, such as the solution of virtual money, is certainly not as fast as that of 2000 middle school students in 8.
"Bitcoin mining machine
So people started using video cards to mine virtual currencies. Later, someone developed a specific algorithm, so that the graphics processor’s virtual currency for the special solution to substantially strengthen, and this is the origin of the mine.
Why was AMD’s video card being snapped up by miners?
Compared with Nvidia graphics cards, AMD graphics cards have a wide range of advantages in general performance, or, in general terms, more streaming processors. Ordinary consumers generally use graphics cards, mainly to play games, while playing games require graphics cards for graphics output, and its computing complexity is far more than the mathematical calculation of bitcoin. As a result, the actual game performance is about the same as the N card and the A card.
But we said before, because the A card processor, so to get virtual currency calculation so that in terms of very suitable, get the solution specific than N card number, so many miners now a large number of A cards for panic buying virtual currency operations to seek profits.
Of course, with the introduction of Pascal Nvidia graphics card, N card in the virtual currency on the current ability is not as before, and A card is a huge difference. Thus, in the current A card is generally out of stock, the middle end of the N card has become the miners retreated for second choice.
What’s the disadvantage of mine card?
Finally, why can’t you choose the mine card when you use the second-hand card?. The miners mining bitcoin is the most important thing is to seek profits. As a result, their graphics cards are running and computing at all times, far more powerful than their everyday game applications. Or to run such a computing day, equivalent to the average person running video cards for one month.
Mining and virtual currency are the basic premises of the multi card gathering place, tens of thousands of cards operation constantly in a room, the heat is quite large, but the miners is not like ordinary consumers as select chassis good cooling conditions that the heat can be released, 7*24 hours of operation like this the card is still under the condition of high temperature, also deepen the degree of aging.
So the doings is the result of loss to dig card prematurely, if buy these cards, the result is unstable, restart things will continue to happen.
And the current manufacturers for mine cards are also strict requirements, such as prohibited the sale of second-hand and shorten the shelf life, if the user purchased the mine card card, after the repair will be a challenge.
I hope that through such a small article to make you understand why today’s AMD card so tight, and later to see the news when you can understand.
