Does mining use video memory

1.

mining, in fact, is a problem-solving process. First, we work out a formula with many answers, and then the dealer releases a random answer every other period of time. An answer is the prototype of a virtual coin. We can see who can calculate the answer at this time, and then this person or these people can divide the virtual coin. When the result comes out, we can find the answer, virtual currency is attached with information such as the computer information and problem-solving time of the tester, so that the virtual currency can be "materialized", that is, it has traceability and uniqueness attributes. At this time, the virtual currency is officially g out

using the graphics card is because the computing method of the graphics card is different from that of the CPU. The CPU focuses on logic computing. The graphics card is simple computing, and mining (that is, solving problems) just needs simple computing power. Therefore, mining with the graphics card

bitcoin miner is the equipment for mining bitcoin. The mining equipment can be ordinary computer or USB miner, It can also be a professional ASIC miner

It is true that ordinary computer CPU can mine bitcoin, but because bitcoin mining has formed a huge instry all over the world, it is difficult for indivials to mine bitcoin with ordinary computers. You need to buy expensive and professional bitcoin

ASIC mining machine

and join the bitcoin miners organization to dig bitcoin, that is, to join a mining pool for mining

First of all, CPU and GPU are designed differently for different missions in the computer:

1. CPU is mainly optimized for serial instructions, while GPU is optimized for large-scale parallel computing

Modern multi-core CPUs aim at instruction set parallelism (ILP) and task parallelism (TLP), while GPUs aim at data parallelism (DLP)

3. GPU often has a larger bandwidth of memory, that is, the so-called video memory, so it will also have good performance in high throughput applications

2. Theoretically, both CPU and GPU operations can be mined
in the early days of the advent of a virtual currency, it was relatively easy to mine. Maybe a CPU with strong enough performance could easily mine the currency
as it becomes more and more difficult to dig money, the CPU has already been unable to cope with the huge computing power required for mining, and the terrible performance of the large-scale stream processor parallel computing in the GPU core of the graphics card is more suitable for mining this kind of parallel computing
therefore, today's professional mining machinery has become the world of GPU and professional chips, in which CPU plays the most coordinating role. Moreover, with the increase of mining difficulty, the demand for the display memory capacity of the mine card is higher and higher. A few years ago, 2-3gb was enough, but now 6GB may not be enough.

3. Mining for computer graphics card requirements are very high, low-end graphics card is not used, so low-end graphics card is not likely to be used to mining.

4. Mining needs the al precision computing power of graphics card
it has nothing to do with video memory
traditionally, amd card retains the ability of double precision calculation. No castration
n card has been castrated greatly. So the computing power is not as good as card a.

5. Today's bitcoin mining uses amd graphics cards, which are not very different from ordinary graphics cards. You can also play 3D games on them for design. The hd7850
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.

6. Call the police. Don't think too much

7. There's a difference. 2G is good

8. This depends on the model of the building's graphics card. The performance of the graphics card depends not on the memory, but on the core performance.
if the building's graphics card is lower than gtx1050 and rx460, there is basically no mining benefit. If the performance is good, it can be used naturally.
