Comparison of mining graphics card

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. 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

4.

1. It depends on whether the core turns yellow. Some parts of the new card will turn pale yellow, but at that time, the color of the protective paint is yellow. The core yellow of the mine card is yellow and burnt yellow caused by long-time and high-frequency use of heat and oxidation

2. Check the screw fixing plate

friends who have used independent graphics cards should know that the graphics cards are fixed on the chassis by screws, while most of the large-scale mining graphics cards are fixed by plastic ties, while the self use cards will not be fixed in this way

Interface

interface refers to the output interface of the graphics card. Before purchasing, you can ask the seller about the interface for connecting the display in daily use, because mining graphics cards usually do not use the display output interface

after the interface is determined, whether the interface has been used for a long time can be judged by checking whether there is st. If there is a lot of st, it will prove that the interface has not been used at all or recently

extended data:

mine cards refer to the cards used to dig bitcoin. They are full loaded for a long time, with short service life and high load all day

the bitcoin mining machine is the computer used to earn bitcoin. This kind of computer generally has professional mining chips, and works by installing a large number of graphics cards, which consumes a lot of power. One of the ways to get bitcoin is to download mining software and then run specific algorithm to communicate with remote server to get corresponding bitcoin

Mining is a process of increasing bitcoin money supply. Mining also protects the security of the bitcoin system, prevents fraulent transactions, and avoids "double payment", which means spending the same bitcoin multiple times. Miners offer algorithms for bitcoin networks in exchange for the opportunity to get bitcoin rewards. The miners verify each new transaction and record it in the general ledger

5. At present, the most valuable currencies for investment are rare ancient coins, which are unnecessary for a large amount of existence, and rare commemorative gold coins issued by the state. These should have the largest value-added space, waste a lot of money, and can be collected if there is more money.

6. blockchain is composed of blocks. A block contains about 400 transactions, which are packaged into a blockchain and then form a tamper proof blockchain
the packer of the transaction is the miner, and the income from the miner's packaged transaction is bitcoin
miner's income consists of two parts:
1. Service charge is required for package transaction (users pay part of bitcoin)
2. A reward (bitcoin) will be automatically generated for each block generated

7. The information transmission of the blockchain itself may be false
1. The provincial characteristics of the blockchain, once included in the block, are irreversible and can not be tampered with, and the information is true and effective, but there is only one case that is false, that is, the information written in the first attempt is false, resulting in the false information stored in the block
2, Basically, it's the application side of the technology

8. Compared with the previous one, the new one is much bigger, about 18 inches, very stable and safe. In addition, the rear ceiling lamp and the rear al USB interface are added, so the practicability is OK
