BTC and GPU

1. 1. CPU is mainly optimized for serial instructions, while GPU is optimized for massively parallel operations
2. Modern multi-core CPU aims at instruction set parallelism (ILP) and task parallelism (TLP), while GPU is 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
4. CPU is a general-purpose operation. In short, it means brainless calculation and violent calculation. Whether it's 100 children sharing apples or simulating the earth, it can be decomposed into the most basic calculation of 1 + 1 = 2. GPU is specially designed to deal with high-order mathematical algorithms, such as calculating the relative positions of light source, object, viewpoint and shadow, which requires trigonometric functions to be piled up. The bitcoin digger uses SHA-256, a secure hash function invented by the US National Security Agency, which is generally used for password encryption and decryption. This algorithm can perform a large number of 32-bit integer right-rotate operations, which is very suitable for GPU which is good at large-scale concurrent computing and password cracking.

2. At least dozens of times as much as CPU, and bitcoin uses OpenCL. The efficiency of 7 series a card is much higher than that of N card.

3. After high-speed computing with the computer composed of AMD graphics card, bitcoin can be generated
1. Unlike most currencies, bitcoin is not issued by a specific monetary institution. It is generated by a large number of calculations based on a specific algorithm and is a virtual currency
2. In order to get bitcoin, you have to use computing machines, many of which are provided by AMD graphics card with high computing power. When bitcoin was hot, AMD's graphics cards were always in short supply, such as HD 7850, HD 7870, HD 5850, HD 5870, R7 270, R 280x, which are the best helpers of bitcoin
3. Later, when someone invented a mining machine that could get bitcoin more quickly, these graphics cards slowly withdrew from the mining stage
in other words, the computer made up of AMD high-speed graphics card was once the main platform for acquiring bitcoin. This is the relationship between them.

4. It's OK. It's easy to use. There are 1960 information type blockchain networks in China and more than 90000 overseas. You can see a lot of information blockchain websites such as "blockchain XX network" directly through the domestic network "blockchain network".

5. After the completion of MLM or identification, it is important to remember that under no circumstances can you remit money first, whether it is franchise fee, deposit or other name,

6. Bitcoin and other virtual coins are booming, and more people are engaged in mining, which also drives the development of mining machine. Mining machine is composed of many graphics cards array, so the mining efficiency is high, so the price of graphics cards has begun to rise, and there are many obsolete graphics cards in the second-hand market, because the long-term high load working life will not be too long, so the second-hand graphics cards should not be bought as far as possible.

7. Mining, you need to use amd
graphics card. Use its
general computing
function to participate in high difficulty computing tasks
n card
has low mining efficiency, no one uses it.

8. In order to dig bitcoin, hardware needs to have very strong parallel data processing capacity and large bandwidth storage capacity. CPU belongs to traditional serial computing processing equipment, and its computing capacity is far less than that of GPU. Moreover, the cache capacity of CPU is far less than that of GPU. Therefore, it is more appropriate to dig this kind of virtual currency with GPU than with CPU

9. Bitcoin is not found, but g out. It is a bit like gold, sometimes called bitcoin gold. There are 21 million bitcoins in total, and now more than 13 million have been g up. Bitcoin's current price is about 800
Mining (the way to get bitcoin) is now basically impossible for ordinary people. From CPU mining, GPU graphics card mining, to ASIC mining (professional mining integrated circuit), mining efficiency soared. It's almost impossible for a person to dig
bitcoin was founded in 2009 and is a new thing now. The future is unknown, so it's better not to get involved.
