What are the parameters of the graphics card related to mining
bitcoin was obtained by CPU in the early days. With the continuous development of GPU speed and the emerging advantages of GPU general computing, miners graally began to use GPU instead of CPU for mining. Bitcoin mining uses SHA-256 hash operation, which will carry out a large number of 32-bit integer cyclic right shift operation. Interestingly, this algorithm operation can be implemented by a single hardware instruction in AMD GPU, while it needs three hardware instructions to simulate in NVIDIA GPU. This one alone brings an additional 1.7 times of computing efficiency advantage for AMD GPU. With this advantage, amd GPU is favored by the majority of miners
advise the landlord not to dig up if the budget is not too much!!! This money is not earned if you want to
the difficulty of bitcoin is increasing. Mining with graphics card is a race against time. The main reason is that the difficulty of mining bitcoin is graally increasing (the reason of bitcoin algorithm design). If a set of platforms can get 1 bitcoin per day according to the current difficulty, then in one month, the platforms with the same computing power will only get 0.8 bitcoins, even the top graphics cards will get 18.2 days (which can't be shut down), and the lowest second-hand hd7750 will need more than 400 (it will take 214 days to get one). Just look at this figure (this is the data in May this year, Now it's more than 18 days)
people can earn money by buying several mining machines (mining machines with dozens of top graphics cards piled together)

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.
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.
1. Six PCI-E slots are provided to connect six graphics cards
2. BIOS optimization, which can be identified by inserting 6 cards, does not need manual adjustment
3. Stable operation and unstable motherboard may cause automatic restart and shutdown, affect efficiency, or cause short circuit graphics card burn out
at present, B250 / B350 mining motherboards are mainly promoted in the market. Some new ones are very interesting, such as 7 cards / 8 cards. However, these schemes have not yet passed the test. There may be unstable factors, and some of them are not in stock. In fact, the previous 8 series are more suitable for mining. The ms-b85-btc made by the furniture factory is a very good mining board. After years of mining scheme verification, 6 PCI-E, BIOS automatic identification, and PCI-E voltage stabilizing capacitor design are added. The mining is stable, and the shutdown cost is low.
in terms of personal experience, qbao network is very simple and easy to use. It is not only a decentralized multi-functional cross chain digital currency wallet with social function, but also integrates multiple functions such as cross chain multi currency wallet, payment and settlement platform, currency trading platform, social group, information quotation, DAPP, etc., which can meet almost all your needs for digital currency in one stop
it is recommended to download and try.

mining is actually using graphics card to dig bitcoin.... In fact, it can be understood as the solution of super equation, which requires super high computing power of graphics card

to dig bitcoin with graphics card. Let the graphics card work with high load, and the eliminated ones become mine cards. Generally, the core PC board on the back of mine cards is seriously discolored

but the stronger the performance of the graphics card, the higher the efficiency
generally speaking, 7990 is the strongest, but it is also the most expensive, and the power consumption is also high
generally speaking, 7970 and 7950 are OK
