Mining machine a card speed fast
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)
I hope I can help you
let's see what others say.
Mine card refers to the graphics card used by bitcoin mining machine, mostly amd graphics card
mine disaster refers to the decline in the price of bitcoin and the sale of second-hand mine cards
bitcoin mining machine graphics card long-term high load operation, graphics card service life will be reced accordingly, so the price will be cheaper
extended data:
bitcoin mining machine is a computer used to earn bitcoin. This kind of computer generally has professional mining chips, and mostly 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
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
-
may be caused by the driver is not completely installed, or the driver version installed does not match the system
-
re install other driver versions, or ask the customer service of the graphics card brand if they need to install the driver for mining and switching< br />
Mining graphics card is faster than CPU, professional mining machine is faster than graphics card because: BTC task is a very simple decryption calculation, does not need too many instructions
That is to say, the task of BTC only needs some specific transistorsthe CPU is used to carry out the mining task. Because the CPU needs many transistors to execute various instructions, many transistors are idle in a cycle
QB is equivalent to RMB. Although many point cards are not equivalent to RMB, they are also similar to the exchange rate, such as 1 yuan to 100 points
this is not to sell as much as you want
many services launched by Tencent require QB. RMB can buy any domestic goods and services that can be expressed in currency, but QB can't. QB can only purchase the services and goods launched by Tencent or the services and goods jointly launched by Tencent and other companies (such as rising recharge)
QB needs promotion, and it can't purchase the real goods compulsorily. We need to sell QB in exchange for RMB, which is the same as selling a piece of goods in exchange for RMB
RMB is a compulsory currency, and it is the only monetary unit in China. You can buy anything and services that can be measured by price. It is just a payment method that can speed up the transaction speed in a certain field in a certain period of time, which is no different from the canteen meal ticket in essence.
