Is a card mining more or n card

1. Dig with n card, you can't even collect the electricity fee... If you want to mine, you'd better use a card honestly

2. Hello, the mining of bitcoin is actually doing distributed computing, and the strongest point of graphics card is floating-point computing. A card and N card are more suitable for floating-point operation than a card. N card should spend more energy on rendering, and a card has more Alu units than n card. At this point, a card is 2-3 times faster, so mining speed with a card is faster

3. A card has more process processors, and its general computing power is stronger than n card. The architecture of a card is more suitable for mining. N card is OK now, but the effect is not as good as a card. This is a fact
let's see what others say.

4. Because of different instructions, a card needs one instruction, n card may need three instructions, and a card has more computing units. As for the graphics card, it is faster than the processor because of different operation modes. GPU is dedicated to floating-point operation, and some CPUs have it, but it is not as good as GPU (for example, Xeon amd has no floating-point operation capability at all)

5. The first phase of a card is hd7850 7870 7950 7970 R9 270-380, which is basically OK, and the 290 power consumption is too high to be used by mine owners.
in the second phase, the above old cards are still available, and the most perfect one is 470 480 570 580 low-end 560, which can also be used to dig lower models. There is no danger.
n card 1060 3G 6G is the most mainstream, 1050ti and 1070 are occasionally used. Especially luxury also used 1080, because the price of 1060 was almost 1080 at that time

6. It's Sha. This is the security mechanism of bitcoin. All transaction records should be packed and divided into blocks, and Sha hash should be calculated. Only blocks with a specific hash value can be recognized by the network. Each block contains the hash value of the previous block to form a block chain. If there are more than one branch chain at a time, only the longest chain is recognized. The counterfeiting of small computing power cannot catch up with the long chain. You can't fake Transactions unless you have 51% of the computing power. Therefore, the more scattered the computing power is, the higher the total computing power of the whole network is, and the more secure the network is.

7. Before 12 cards mining, an card must be used to mix and match. This is mainly e to the scheling and management mechanism of windows. However, such stability will be poor, and scheling will bring certain performance loss. As for installing drivers, it is more likely to be a nightmare. In fact, with the advent of ethos mining operating system and Yingtai's full support for ethos, It's very simple to realize 12a or 12n. Both efficiency and stability are greatly improved. Therefore, of course, 12a or 12n is preferred.
