"Graphics card mining" is actually to use the graphics card to dig bitcoin, so that the graphics card can work with high load, and the eliminated ones will become mine cards. Generally, the core PC board on the back of mine cards is seriously discolored< br />
Mining, in fact, is a problem-solving process. First, we work out a formula with many answers, and then the dealer releases a random answer every other period of time. An answer is the prototype of a virtual coin. We can see who can calculate the answer at this time, and then this person or these people can divide the virtual coin. When the result comes out, we can find the answer, virtual currency is attached with information such as the computer information and problem-solving time of the tester, so that the virtual currency can be "materialized", that is, it has traceability and uniqueness attributes. At this time, the virtual currency is officially g out
using the graphics card is because the computing method of the graphics card is different from that of the CPU. The CPU focuses on logic computing. The graphics card is simple computing, and mining (that is, solving problems) just needs simple computing power. Therefore, mining with the graphics card
bitcoin miner is the equipment for mining bitcoin. The mining equipment can be ordinary computer or USB miner, It can also be a professional ASIC miner
It is true that ordinary computer CPU can mine bitcoin, but because bitcoin mining has formed a huge instry all over the world, it is difficult for indivials to mine bitcoin with ordinary computers. You need to buy expensive and professional bitcoin ASIC mining machine
and join the bitcoin miners organization to dig bitcoin, that is, to join a mining pool for mining
First of all, CPU and GPU are designed differently for different missions in the computer:1. CPU is mainly optimized for serial instructions, while GPU is optimized for large-scale parallel computing
Modern multi-core CPUs aim at instruction set parallelism (ILP) and task parallelism (TLP), while GPUs aim at data parallelism (DLP)3. GPU often has a larger bandwidth of memory, that is, the so-called video memory, so it will also have good performance in high throughput applications

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
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
graphics card mining to make money:
1. Determine the virtual currency to be mined
Generally, there are professional graphics cards to mine, and the mine is actually bitcoin. Users download the mining software from the computer and then run a specific algorithm. After communicating with the remote server, they can get the corresponding bitcoin. Most of them work by burning the graphics card, so the power consumption is large
the graphics cards and mine cards are usually ATI chips. The bitcoin market is not good, so the miners take out their mining cards and sell them as second-hand
what is mining
to put it simply, mining is to use the chip to perform a calculation related to the random number, and get the answer in exchange for a virtual coin. Virtual currency can be exchanged for the currency of each country through some way. The stronger the computing power, the faster the chip can find this random answer. Theoretically, the more virtual coins can be proced per unit time. Because it's about random numbers, you can only get rewards if you happen to find the answer. It's possible that one chip will find the answer in the next second, or ten chips won't find the answer in a week. The more chips compute at the same time, the easier it is to find the answer, and the mining machine with built-in multi chips appears. And a number of mining machines to form a "mine" at the same time mining is to improve efficiency. In the mine pool, multiple "self-employed" join an organization to mine together. No matter who finds the answer and digs out the virtual coin, everyone gets the corresponding reward according to the calculation ability of contribution. This way can make the income of "self-employed" more stable
relationship between mining and graphics card
the stronger the computing power of ant miner, the easier it is to dig out virtual coins. Accordingly, when the more virtual coins are g out, the difficulty of mining will be increased accordingly, so as to control the yield of virtual coins. The virtual currency is not unlimited. The total number of bitcoin is 84 million
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
Through the operation of the processor in the graphics card, the problem can be solved and the reward can be obtained. Generally, they are digital currencies, such as bitcoin, lettercoin and so on. The difficulty of answering questions is different, so are the rewards, and the calculation data. And this kind of mining needs 24-hour non-stop calculation data, so the loss of graphics card is great
The mine card of graphics card is the graphics card used by bitcoin mining machine
Mining card is a graphics card that is specially used for general calculation to earn network currency "bitcoin". Bitcoin can be proced with specific programs, and then sold to people in need to be able to exchange real money, or mining for short
because this program needs a lot of repeated calculations, it is more efficient to use a card with more sp. Because of the full load operation all year round, there are many uncertain factors in the mining card
extended data:
mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it is only hd6770, the computing power after "group" can surpass the single graphics card of most users
and this is not the most terrible. Some mining machines are made up of more such graphics card arrays. When dozens or even hundreds of graphics cards come together, the graphics card itself costs money. Considering the hardware price and other costs, there is a considerable expenditure in mining
in fact, there are many kinds of mining devices. Guiminer, which is small and easy to use, is recommended. It can support CPU, oepncl, CUDA and other computing modes
in this way, devices including CPU and graphics card can achieve the maximum performance, and then acquire bitcoin more quickly

overview
graphics card, also known as video card, is an important part of the computer. It undertakes the task of outputting display graphics. For people who like to play games and engage in professional graphic design, graphics card is very important. The display chips of mainstream graphics cards are mainly made by NVIDIA (NVIDIA) and AMD (ultra micro semiconctor). Generally, the graphics cards with NVIDIA display chips are called N cards, while the graphics cards with AMD display chips are called a cards[ 1]
computers with high configuration all contain graphics card computing core. In scientific computing, graphics card is called display accelerator[ 1]
Video chipset is the main processing unit of graphics card, so it is also called graphic processing unit (GPU). GPU is the first concept put forward by NVIDIA company when it released geforce 256 graphics processing chip. Especially when dealing with 3D graphics, GPU makes the graphics card less dependent on CPU, and completes part of the work originally belonging to CPU. The core technologies of GPU include hardware T & L (geometry conversion and illumination processing), cubic environment material mapping and vertex blending, texture compression and bump mapping, al texture four pixel 256 bit rendering engine, etc[ 1]
all kinds of 3D special effects supported by the graphics card are determined by the performance of the display chip, and what kind of display chip is used roughly determines the grade and basic performance of the graphics card, such as NVIDIA GT series and AMD HD series[ 1]
there are many ways to measure the quality of a graphics card. In addition to using test software to test and compare, there are many indicators for users to compare the performance of a graphics card. The main factors that affect the performance of a graphics card are the frequency of the graphics card, display memory and other performance indicators [1].
1g version is the most popular. This model can well balance the mining speed and price
in other words, there are a lot of "mining machine graphics cards" on Taobao, because these graphics cards use less materials under the same core and basically unchanged hash speed, such as recing video memory to improve the performance price ratio (the size of video memory has little to do with the mining speed), which can shorten the time to recover the cost
in short, the graphics card of mining machine is the core of common high-end graphics card + the workmanship of low-end graphics card, or some cheap medium and high-end public graphics card.
