Graphics card computing power test software

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. The unit of mining efficiency is generally hash / s, that is, the amount of hash value that can be obtained per second. GPU can reach the level of megahash / s.
gtx1060 mining computing power reaches 18.7mh/s, which is a little behind rx470 mining computing power of 22.4mh/s

3. You can refer to the following, according to some commonly used graphics cards in the Internet bar market, sort out the price and calculation power of a related graphics card, as well as the expected return to the current period, It can be used as a reference:
power consumption: 243w
computing power: 22.4m
price of graphics card: 1999 yuan
number of eth g every 24 hours: 0.015
revenue generated every 24 hours: 24.48 yuan
expected payback time: 81.66 days
power consumption: 159w
computing power: 24.3m
price of graphics card: 1599 yuan
price of graphics card: 1599 yuan
every 24 hours Number of time digging eth: 0.017
revenue generated every 24 hours: 27.9 yuan
expected payback time: 57.31 days
video card of radon RX 480

4. 1. According to the mining software, the larger the value, the faster the "speed" in the software

2. Different mining softwares have different algorithms and ranking.

5. Suggestions: first, the performance of this graphics card is OK, and the low-end graphics card that can share memory with an independent graphics card must be
Second, even if the performance is shared, it will not improve much

6. APU series no matter which one can't compare with i5 4590, APU series focuses on strong performance. You should compare the fx8300 to the i5 4590. That's the same level

More than 500W power supply

sapphire rx580 full load power to more than 200 watts, plus CPU and other hardware power consumption, need more than 500 watts of power supply

If the power supply is

500, it is necessary to pay attention to whether it is rated power. The value of rated power is the rated voltage of the electrical appliance multiplied by the rated current. If the actual power of the graphics card is greater than the rated power, the electrical appliances may be damaged; If the actual power is less than the rated power, the graphics card can not operate normally

extended data:

the power of power supply can be divided into rated power, maximum power and peak power

rated power: the ambient temperature is between - 5 ~ 50 ℃, the input voltage is between 180V ~ 264v, and the power supply can stably output power for a long time

maximum power: at room temperature, when the input voltage is between 200V and 240V, the power supply can stably output power for a long time, and the maximum power is generally about 15% higher than the rated power. For example, the rated power of Xingu nuclear power 325pq is 250W, and the maximum power is 287w, which is close to 300W

peak power: the maximum power that the power supply can achieve in a very short time, and the time can only last between a few seconds and 30 seconds. The peak power is related to the operating environment and conditions, which is not a definite value, but the peak power can be very large, which is very easy to mislead users. For example, the rated power of Xingu nuclear power 325pq is 250W, and the peak power reaches 350W. Obviously, only the rated power and maximum power have practical significance

8. The hook itself is not able to play ~ need hardware (graphics card) and driver support. Even the super performance 4850 and 4870 are blank. However, some new low-end cards are ~

graphics computing only represents a trend now, which has no practical significance. CUDA Programming is too difficult and lacks software support. Moreover, once you start graphics computing, you will extremely rece your fluency when playing games.
