Graphics card mining power up and down
"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 />
A graphics card, a software that can earn bitcoin. Inject new bitcoin (data hashing) into the whole bitcoin market, and then the market will have a certain incentive mechanism (allocate bitcoin to you in proportion). Because if you don't get it, no one will do it, just like your computer is a miner, and bitcoin is the reward
a card. To put it bluntly, it depends on the frequency and SP
,
the better the a card, the stronger the mining.
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:

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
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.
Mini excavators with the weight of less than 6 tons, small excavators with the weight of 6-15 tons, medium excavators with the weight of 15-30 tons, large excavators with the weight of 30-150 tons, and super large excavators with the weight of more than 150 tons. Sany Heavy Instry has more than 200 tons of super large hydraulic excavator
the three most important parameters of excavator are operating weight (mass), engine power and bucket capacity. Common excavator structures include power device, working device, slewing mechanism, control mechanism, transmission mechanism, walking mechanism and auxiliary facilities. The transmission mechanism transmits the power of the engine to the hydraulic motor, hydraulic cylinder and other executive elements through the hydraulic pump, and promotes the action of the working device, so as to complete various operations
the materials excavated by excavators are mainly soil, coal, silt and soil and rock after pre loosening. From the development of construction machinery in recent years, the development of excavator is relatively fast, excavator has become one of the most important construction machinery in engineering construction
extended data
there are two common excavator driving modes: internal combustion engine driven excavator and electric drive excavator. Among them, electric excavator is mainly used in plateau hypoxia and underground mine and some other flammable and explosive places
according to the different scale, excavators can be divided into large excavators, medium excavators and small excavators
according to the different walking modes, excavators can be divided into Crawler excavators and wheel excavators
According to different transmission modes, excavators can be divided into hydraulic excavators and mechanical excavators. Mechanical excavators are mainly used in some large mines According to the use, excavators can be divided into general excavators, mining excavators, marine excavators, special excavators and other different categories According to the bucket, excavators can be divided into forward excavator, backhoe excavator, dragline excavator and grab excavator. The front shovel excavator is mostly used to excavate the materials above the surface, and the backhoe excavator is mostly used to excavate the materials below the surfacevirtual currency refers to non real currency. Well known virtual currencies, such as online currency of Internet company, q-coin of Tencent company, q-point and voucher of Shanda company, micro currency launched by Sina (used for micro games, Sina reading, etc.), chivalrous Yuanbao (used for chivalrous road game), silver grain (used for bixue Qingtian game), and popular digital currencies in 2013 include bitcoin, Laite coin, infinite coin, quark coin, zeta coin, etc Barbecue coins, pennies (Internet), invisible gold bars, red coins, prime coins. At present, hundreds of digital currencies are issued all over the world. The legend of "bitcoin, Wright silver, infinite copper, pennies aluminum" is popular in the circle
network virtual currency can be roughly divided into
[1] the first category is familiar game currency. In the era of stand-alone games, the protagonist accumulates money by knocking down the enemy, entering the gambling house to win money, and using these to buy Herbs and equipment, but it can only be used in his own game console. At that time, there was no "market" between players. Since the establishment of Internet portal and community, the realization of game networking, virtual currency has a "financial market", players can trade game currency
[2] the second type is the special currency issued by the portal website or instant messaging service provider, which is used to purchase the services in the website. The most widely used is Tencent's q-coin, which can be used to purchase membership, QQ show and other value-added services
[3] the third kind of virtual currency on the Internet, such as bitcoin (BTC), lightmoney (LTC), etc. bitcoin is an electronic currency proced by open-source P2P software. Some people also translate bitcoin as "bitcoin", which is a kind of network virtual currency. It is mainly used for Internet financial investment, and can also be directly used in daily life as a new currency
[4] the application of computer communication technology and the development of Internet as a new media are the technical basis of network marketing. Internet was born in the 1960s. With the development of network protocols and related hardware and software procts, Internet has graally changed from military to commercial and civil. From the 1990s, the Internet has graally entered into the daily life of society. As a matter of fact, the Internet, as an emerging media, has developed faster than all other technologies in the past. It took 38 years for radio to reach 50 million audiences, 13 years for television, and only 3-4 years for Internet. Therefore, the Internet is considered to be the technological change that has the greatest impact on the world economy in the past 100 years
