a card. To put it bluntly, it depends on the frequency and SP

Video card (graphics card) full name display interface card, also known as display adapter, is the most basic configuration of computer, one of the most important accessories. As an important part of the computer host, the graphics card is the equipment of digital to analog signal conversion, and it undertakes the task of output display graphics
the graphics card is connected to the main board of the computer, which converts the digital signal of the computer into an analog signal for the display. At the same time, the graphics card still has the ability of image processing, which can help the CPU work and improve the overall running speed. For those engaged in professional graphic design, graphics card is very important. Civil and military graphics chip suppliers mainly include amd (ultra micro semiconctor) and NVIDIA (NVIDIA). Today's TOP500 computer, including graphics card computing core. In scientific computing, graphics card is called display accelerator
Graphics card mining is a process of increasing the bitcoin money supply
the reason why the graphics card is used is that mining is actually a competition of performance and equipment. The mining machine is composed of graphics card array. 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
computers have professional mining chips, and most of them work 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
extended data
bitcoin does not rely on the issuance of specific monetary institutions, and is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
the bitcoin system is composed of users (users control the wallet through the key), transactions (transactions will be broadcast to the whole bitcoin network) and miners (the blockchain is generated by competitive computing to reach a consensus at each node, and the blockchain is a distributed public authoritative account book, including all transactions in the bitcoin network)
bitcoin miners manage the bitcoin network by solving the problem of workload proof mechanism with certain workload - confirming transactions and preventing double payment. Because hash operation is irreversible, it is very difficult to find the random adjustment number of matching requirements, which requires a continuous trial and error process that can predict the total number of times
when a node finds the solution matching the requirements, it can broadcast its results to the whole network. Other nodes can receive the new data block and check whether it matches the rule. If other nodes find that they really meet the requirements (the operation target required by bitcoin) by calculating the hash value, then the data block is valid, and other nodes will accept the data block
The miner is better
-
the electricity charge for mining with graphics card is very high, and the performance is not high, so it can't even earn the electricity charge
-
mining is an investment more than time and speed. We should try to dig more money in the shortest time. Therefore, the professional mining machines of BTC now stress the characteristics of simple operation, small footprint and low power consumption. For example, Yingtai has developed a professional mining motherboard with a computing power of 23.488g/hash, and the proct model is btc-24gh< br />
secondly, the computer needs to be running all the time and can't be turned off for mining, which requires a lot of computer. It is harmful for each part to do a lot of calculation for a long time, and it also requires high power supply for the computer
mining can't be powered off, and it needs to be recalculated after power off. Graphics card long time to do a lot of calculations will lead to greatly shorten the life of the graphics card, so their own home, do not recommend mining, mining is not as expensive as electricity
Bitcoin was obtained by CPU in the early days. With the continuous development of GPU speed and the emerging advantages of GPU general computing, miners graally began to use GPU instead of CPU for mining. Bitcoin mining uses SHA-256 hash operation, which will carry out a large number of 32-bit integer cyclic right shift operation. Interestingly, this algorithm operation can be implemented by a single hardware instruction in AMD GPU, while it needs three hardware instructions to simulate in NVIDIA GPU. This one alone brings an additional 1.7 times of computing efficiency advantage for AMD GPU. With this advantage, amd GPU is favored by the majority of miners
advise the landlord not to dig up if the budget is not too much!!! This money is not earned if you want to
the difficulty of bitcoin is increasing. Mining with graphics card is a race against time. The main reason is that the difficulty of mining bitcoin is graally increasing (the reason of bitcoin algorithm design). If a set of platforms can get 1 bitcoin per day according to the current difficulty, then in one month, the platforms with the same computing power will only get 0.8 bitcoins, even the top graphics cards will get 18.2 days (which can't be shut down), and the lowest second-hand hd7750 will need more than 400 (it will take 214 days to get one). Just look at this figure (this is the data in May this year, Now it's more than 18 days)
people can earn money by buying several mining machines (mining machines with dozens of top graphics cards piled together)
I hope I can help you
a card, that is to say, it depends on the frequency and SP
,
the better the a card, the stronger the mining.
Mining
Mining times: recover a little every two minutes. Every time you dig a grid, you will spend a mining time
reset the mining area back to the original state: the manual refresh device of the mining area is updated every two days
it only takes a few seconds to dig the soil, and it takes a little time to dig. It takes a lot of time, ranging from 20 minutes to 2 hours, to dig all kinds of gems, diamonds and Titans
the detonator can clear the time immediately, but the bigger the detonator is, 5-6 pieces of different kinds of ores can be obtained with each broken purple gold rock
hoe level: will be improved with the map opening event
ore type: ordinary ore (copper, tin, iron, silver, gold), various gems, diamonds, troll statues, and various soul crystals
ore usage: it can be used to forge equipment and open backpacks
detonator: clear the mining time immediately It's mainly used to dig zijinyan. There's no way to dig zijinyan. It can only be blasted with detonators.)
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 is500, 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
