What kind of graphics card is good for mining

1.

The graphics card market in 2017 is the most special in recent years. In the past few years, no graphics card will increase its price by 100% a few months after its release. RX 580 has achieved this goal. Together with all the graphics cards below 3000 yuan, it has broken through the premium point in an irresistible manner. All this happened with the bitcoin price breaking through 3000 US dollars. After miners swept the RMB 2000 RX 580, the price of low-end RX 560 and even GTX 1050 Ti increased to varying degrees. However, is the price directly proportional to the ability of hash algorithm? Recently, we did a test to collect the new generation of graphics cards at various prices on the market, test the mining speed of Ethernet and bitcoin, and see which card has the highest cost performance

Different from the thousand yuan market, this wave of mining tide has a great impact on high-end graphics cards. In the test results, RX 580 and Rx 480 have almost reached the bottom of GTX 1070. Moreover, the price of Rx 580 is even competing with that of GTX 1070, so the miners directly swept the 3000 yuan market when GTX 1060 3gb / 6GB is out of stock, and GTX 1070 is basically out of stock. The more advanced GTX 1080 is also out of stock, but it's not clear whether the players are forced to go directly to the high-end card or the miners extend their claws to this market. The situation of GTX 1080 ti is only slightly improved, but it's not much better. However, not everyone can afford the 6000 yuan graphics card. Only the top players will be affected, but it's just a narrower choice. It's not the case that the rich can't buy it

summary:

to mine, the first choice is the graphics card with more than 3gb video memory, which is the basis. In addition, the core frequency will affect the mining speed. We have two GTX 1080 cards on hand, one is public version, and the other is MSI GTX 1080 gaming X. the operating frequencies of the two cards are 1885mhz and 1936mhz respectively. After testing, because of the frequency, the latter will be about 4% faster than the former in actual mining. The advantages of high-frequency graphics card are highlighted

So Xiaobian's opinions and suggestions are as follows:

the low-end card and the old architecture card are not suitable for mining. GTX 1080 ti is an extreme, with the most powerful performance, but the price is not suitable for large-scale procurement. The mining speed of a card with the same location is much faster than that of N card, The cost performance of GTX 1060 3gb is higher than that of GTX 1060 6GB. The frequency and the number of stream processors / CUDA have a great influence on the performance of the card. The size of video memory has no influence on the mining. It's enough. Different video cards will have different profits if they dig different coins. If you want to further explore, you need to test several currencies, Limited to space, we only select two representative currencies to test

as long as the mine disaster does not occur, the shortage will last for a long time. However, if there is a mine disaster, a large number of second-hand mine cards will directly enter the market. These cards are always running at full load and full speed, and their service life is greatly shortened compared with that of ordinary users. Even if the price is lower, they will roll over at any time, There is no need to start at all. Moreover, the second-hand market will be directly disrupted. At that time, it will be difficult for some normal users to get out of the second-hand market, and the deep-water fish's Dragon killing knife will explode the galaxy. Now it is said that NVIDIA is making some graphics cards without display output interface, which are provided to miners as mine cards. With a certain capacity, if the mine card still can't satisfy the miners, won't the miners buy the graphics card in the consumer market? The only function of these special mine cards is to prevent mine cards from flowing into the second-hand market, which can not alleviate the current shortage of graphics cards

2. Rx460 / 560 and rx470 / 570 are the most cost-effective. Compared with the price, vega64 has the largest profit. Although vega64 has the highest mining capacity, it is only twice as much as 470, and the price is more than three times. Therefore, two vega64 pieces can be exchanged for six rx570 pieces, but the computing power is only two-thirds of the latter. When it comes to rx560, the situation is similar
rx470 / 570 is the first choice, followed by 460 and 560

3. If 900 yuan graphics card, don't mine. We can't find it.

4. You can install three graphics cards with PCI-E adapter. You can read the tutorial online. The cheapest graphics card is 7770, and the speed of a single card is 200. If you make three graphics cards, the average monthly income is about 1000-1200, because you don't need to pay for electricity, so this part is not excluded for you

mining machine risk

1. The problem of electricity charge

in order to make the graphics card full load for a long time, the power consumption will be quite high, and the electricity charge will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned

2. Hardware expenditure

mining is actually a competition of performance and equipment. Some mining machines are composed of more such graphics card arrays. With dozens or even hundreds of graphics cards, the cost of hardware and other costs is very high, and there is a considerable expenditure in mining

3, currency security

the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but the frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin

6. The entry-level graphics card has no effect, but 1030 can't be mined. 1050ti has plenty of goods, but 1050ti's price is embarrassing and it's not recommended.
at present, only gtx1060 5g version is not affected in the middle end. This card weakens the mining ability, the price is good, and the performance is also weakened, Moreover, this special network card can only be purchased from the omnipotent one.
a new high-end graphics card is coming out immediately. It seems that the 1080 and so on have no purchase value now. Of course, if they are enough local tyrants, they don't need to care about these things

7. Generally, amd graphics card has many stream processors, and mining is fast. In those years, 68707850280 (without x) was popular. Now, the new card mining is more valuable than 470d, which is worth 470 yuan. The cost performance ratio and efficiency ratio are more prominent.

8. He's using a special chip

9. It's not good. A card has been cut down a lot. You can buy mining machine directly. Now the mining capacity of mining machine is thousands of times of that of graphics card with the same price.

10. 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.
