Cheap display card for mining machine

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. Suitable for mining model is gtx1060 gtx1070 1080 1080ti, the old gtx970 980 is OK, that is, the power consumption is higher
RX 390 RX 470 480 560 570 580 and higher RX Vega
of course, Titan is also OK. You look down on miners

3. 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

4. At first glance, the owner is a novice. Now the era of graphics card is over. Mining is becoming more and more difficult. The graphics card can't dig anything. Of course, the miner is suitable. As for Laite coin, Shanzhai coin and so on, most of them are based on scrypt algorithm, and now they are also the places for mining machinery manufacturers to compete. However, only gridseed chrysanthemum mining machine has appeared. It supports double algorithm, and most counterfeit coins can be g. Anyway, it's not wise to buy a graphics card now. Let's judge for ourselves.

5. 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

6. It's probably tens of thousands of yuan. If you buy more, you'll get back more mining machines. Now you don't earn money. Damn it, you still need electricity, so it's not recommended.

7. 1, because the task of BTC is a very simple calculation of decryption, it does not need too many instructions. In other words, the task of BTC only needs some specific transistors to be executed

2. The CPU is used to perform mining tasks. Because the CPU needs many transistors to execute various instructions, many transistors are idle in a cycle. The speed is relatively slow

3, in order to enhance the ability of displaying images, the graphics card saves a lot of transistors that have nothing to do with the display function, so the graphics card can only display pictures, but it is much faster than the CPU in the task of displaying pictures. BTC needs to perform the same task as the graphics card, so the mining of the graphics card is faster than the CPU, So a card is more suitable for mining.

8. Tezos (xtz), penta public chain (pnt) and lisk (LSK) are all powerful projects in the bottom public chain. LSK is the first decentralized application solution completely written in JS. The code has been open source, which is very attractive in the concept of decentralization. Pnt (Fanta network) is the underlying basic chain and protocol of the next generation of blockchain value Internet. I personally understand that the next generation is blockchain 3.0. The first generation is recognized as bitcoin, and the second generation is Ethereum. It's just that it hasn't landed yet. It's the focus of attention.

9. Almost no money. You can go to Taobao or Xianyu to have a look. Recently, more and more people begin to sell mining machines. Moreover, the situation of bitcoin is not optimistic. The price of graphics cards is generally high, and it is likely that they will not be able to get their money back before the next mining disaster
