CPU contributes computing power

1.

bitcoin mining machine is a kind of computer used to earn bitcoin. This kind of computer generally has professional mining chips and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server

mining is actually a competition of performance and equipment, and a competition of computing power among miners. Miners with more computing power are more likely to dig bitcoin. With the increase of computing power in the whole network, it is more and more difficult to dig bits with traditional devices (CPU, GPU). People have developed chips specially used for mining. Chip is the core part of mining machine. The process of chip operation will proce a lot of heat, in order to cool down, bitcoin miner is generally equipped with heat sink and fan

bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce

bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high

2. 1. The meaning of CPU calculation once is that CPU performs "bit calculation" once, for example, 2 + 3 = 5, and binary is 0010 + 0011 = 0101. If there are three bits in total, the computer will calculate three times. 2. As for what this number is related to, that is, the higher the CPU frequency, the more the number of operations per unit time

3. The computing power of CPU is related to the number of CPU cores, the frequency of core and the ability of single clock cycle of core
the ability of double precision floating-point computing is commonly used to measure the scientific computing ability of CPU, that is, the ability to process 64 bit floating-point data

the processor supporting avx2 can perform 16 floating-point operations in one core and one clock cycle, Also known as 16flops
CPU power = number of cores x frequency of cores x 16flops
processors supporting avx512 can perform 32 floating-point operations in one core and one clock cycle, also known as 32flops
CPU power = number of cores x frequency of cores x 32flops

4. I54590 is a four core, four thread, three-level cache is 6MB. The i7 4790 is a 4-core 8-thread, 3-level cache of 8MB. CPU is not only determined by the dominant frequency.

5. No, if multiple programs are running at the same time, the al core 2.2g is better than the single core 4.4g. If it is a single task, the 4.4g single core is certainly better. Now u is developing towards multi task operation. For example, if you watch a movie with 4.4g, it's no problem. If you open a few web pages or games at the same time, the cup will happen, but the al core 2.2g is different.

6. E-cash can only be consumed by flash payment, so you can ask the local ICBC where there is a POS machine supporting flash payment, go to some cooperative merchants of ICBC, and support chip card consumption. We can do things like noodle king and Baiguoyuan. I don't know if you can do it. If you don't have it, you can only cancel the card. You need to withdraw the money from it

7. CPU computing power has special running points. It depends on what you do. There are special running points software for different items
quantity * dominant frequency is wrong.

8. Only Intel and AMD, NVIDIA IBM, Intel AMD and many other servers, the best IBM, Intel
for home use, Intel and AMD, CPU computing power, how many calculations per second
