What graphics card does bitcoin need

1. bitcoin was acquired by CPU in the early days, e to different working methods. CPU is mainly to do full-function operation, the number of core is small, and the operation ability is limited (GPU is a very large number of operation core for special operation). With the advantages of GPU general computing and the continuous development of GPU speed, 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. At present, it has left GPU computing. At present, miners have begun to widely use integrated circuit (ASIC) mining machine. Although this kind of mining machine can only be used to dig bitcoin, other currencies can not be used yet, but a single mining machine can reach the level of megabytes, especially loved by mine owners in Sichuan, Guizhou and other regions. Tens of thousands of professional mining machines are in full swing, and retail investors are unlikely to get bitcoin in the face of such powerful computing power.

2. He's using a special chip

3. Four 290 graphics cards are selected in the configuration list. This is mainly because the 7990 graphics cards on the market are out of stock, and the performance of 290 is much higher than that of 280x. The official quotation is more than 3k, but it is not impossible to get the goods at the price of 2700-2800 in the actual market, so 290 graphics cards are selected. The purchase of the chassis is particularly important. The game fierce tiger shark chassis with the whole tower structure has good heat dissipation, and the 10 expansion slots are enough to control 4 graphics cards. The power supply is the cool all-in-one water-cooled radiator, and the effect with the 4th generation CPU is quite good. The price is also quite appropriate.

4. Generally speaking, AMD's graphics card is more suitable for the most mining graphics card e to the factors of architecture, price and so on
hd7990 is the current king. It is said that the electricity charge for mining each bitcoin is 130-140 yuan. In other words, a monster card like hd7990 needs to work for about 20 days to get a bitcoin. A bitcoin may consume 300 watts of power, not counting the loss of computers
in addition to the graphics card, other hardware of the mining platform will also consume electricity. CPU / motherboard, memory, hard disk, including the power supply for the whole machine, will still need electricity because there is no 100% conversion rate. Compared with the display that can be turned off in pure standby, they have to intervene
the faster the graphics card mining speed is, the less unnecessary power consumption will be consumed for each bitcoin acquisition. In this case, the graphics card with fast computing speed often has more advantages. If a multi card platform is established, the net profit per unit time will be higher
the lower the performance of the card, the more power it consumes on average
in a word! Investment must be cautious.

5. It must be a card. Now most of them are digging with 7850

6. Wake up, now is not suitable, unless you are a local tyrant, directly buy "Butterfly" to dig, or electricity is not enough to pay!
