Graphics card mining is more economical

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. CPU can be used to mine, but the efficiency of CPU mining is not as high as graphics card. In order to make money, absentees have to calculate the input-output ratio. The input-output ratio of mining with graphics card is higher, so we graally start mining with graphics card. Now you should understand why mining with graphics card does not use CPU.

3. 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

4. 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

5. Simply put, it is to use your graphics card to work for others in your spare time in exchange for compensation. Only AMD's graphics card is suitable.

6. Bitcoin is a member of the virtual currency. The data is calculated by a specific algorithm, and the total number of data is fixed. Therefore, bitcoin is less and less g, and it is more and more difficult to dig. Recently, bitcoin's rise is quite high, which has spawned a group of new miners to enter the pit. It can only be said that they are waiting for the mine disaster. Amd graphics card is generally preferred in mining, because in recent generations, n card tends to simplify the basic floating-point operation and improve the utilization rate of the architecture to the core, while a card has always liked the heap stream processor with crazy heap parameters, just what mining needs is the basic double precision floating-point operation ability, so a card is generally preferred in mining.

7. Why can't I buy it:
1: the working state of the mine card is 24 hours a day, full load and complex floating-point calculation, which does great harm to the original of the graphics card itself. The mine card mines for one day. Equivalent to about 10 days for ordinary users. So buy mine card is very easy to damage
2: as long as the graphics card is used in mining, the manufacturer will not guarantee it, or only guarantee it for half a year. Now, when you buy a graphics card, there is a label on its shell: "if the graphics card is used for mining, there is no warranty in case of problems".

8. This is decided by the design of BT coin software. Its design structure matches the architecture of the graphics card, and it runs more efficiently. Therefore, it runs with the graphics card. The CPU can't run, but it's not as efficient as the graphics card,

9. 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.

10. There are risks in digital currency transactions. In addition to the prevalence of fraud platforms, it is difficult to distinguish the true from the false. You'd better ask professionals. Otherwise, some fraudsters have opportunities to take advantage of them. After they are lost by the routine, they will be hard to recover by calling the police
