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
For example
a 4-sheet R9 280x graphics card miner. About 2.9m
power consumption:
the rated power of each graphics card is about 250W, and slightly overclocking is about 300W. Four graphics cards, 1200W
platform: motherboard, CPU, hard disk, etc., which add up to no more than 200W
display, mining machine is basically no display
the total power is about 1400W. 33.6 degrees a day
if the caption is only for ordinary household desktop computers, it is not easy to calculate, because the key is the power consumption of the graphics card. The power consumption of ordinary graphics card is about 150W. And then add the others according to 200W, a total of 350W. 4.2 degrees a day
They are used to evaluate the performance of the processor
Top / W is used to measure how many trillion operations a processor can perform under the condition of 1W power consumptionGOPs (Giga operations per second), mops (milling operations per second). 1gops represents that the processor can perform one billion (10 ^ 9) operations per second, and 1mops represents that the processor can perform one million (10 ^ 6) operations per second. Tops, GOPs and mops can be converted to represent the number of times that can be processed per second, but the unit is different
extended data:
commonly used double precision floating-point computing ability measures the scientific computing ability of a processor, that is, the ability to process 64 bit floating decimal point data
the single instruction length of avx2 processor is 256bit, and each intel core is supposed to contain two FMAS. One FMA can perform two times of multiplication or addition in one clock cycle, so the processor can perform 256bit * 2fma * 2m / A / 64 = 16 floating point operations in one core and one clock cycle, also known as 16flops, namely floating point operations per second
the length of a single instruction of avx512 processor is 512bit, and each intel core is supposed to contain two FMAS. One FMA can perform twice multiplication or addition in one clock cycle, so the processor can perform 512bit * 2fma * 2m / A / 64 = 32 floating-point operations in one core and one clock cycle, also known as 32flops
confirm whether your phone is iPhone 4 8GB black. Otherwise, it can be confirmed that the machine is a high imitation machine. It's not a real machine
the beginning of serial number c3k is the official renovation, which is provided for after-sales service to replace the faulty machine.

bitcoin is actually a useless string of numbers, but it is recognized as useful, just like diamonds, antiques, calligraphy and paintings, game skin and so on. They can't be eaten or used, but we will recognize their value
"mining" just allows more people to participate in the construction of blockchain network. Is it really good that so many electricity charges are used to "calculate" a series of virtual values? Bitcoin is not a hedge. The price of bitcoin fluctuates greatly. Speculation on bitcoin may become rich overnight or become poor overnight. Bitcoin is not as safe as it claims. In 2014, the world's largest bitcoin trading website, mtgox, was hacked and went bankrupt, and the $467 million worth of bitcoin evaporated instantly. Criminals use it to launder money, evade taxes and so on. It is also quite difficult for the government to investigate. The above personal opinions are welcome to be criticized and corrected. Agree with me, please click like before you go, thank you! Like me, please pay attention to me, thank you again
as long as there is enough capital and cheap electricity, as well as computers with superior performance, the payback cycle is very short. Moreover, if you are a believer in bitcoin and want to collect money, mining is undoubtedly more cost-effective than speculation. Take the latest miner on the market, ant miner S19 Pro 110t, for example. The market price is about 20000 yuan, the calculation power is 110th, the total power is 3250w, the electricity charge is 0.3 yuan / kWh, the daily output is 0.000924 bitcoins, the income is about 59.27 yuan, and the electricity charge is 23.4 yuan, the daily net income is 35.87 yuan. If the price is in equilibrium, the payback cycle is about one year and seven months
the annual income of bitcoin cloud computing power mining can be more than 20%, which is far higher than most of the investment. It is the best choice for most Xiao to invest in bitcoin mining. As an early established cloud computing mining platform in the instry, easy direct mining provides users with diversified investment options. The calculation power of the mining machinery can be checked in real time, the income will arrive every other day, and it will be redeemed free of charge when it is e. At present, bitcoin mining still has a large income. As long as there is enough capital and energy, we can get high income by mining bitcoin. But for Xiao, it is still the best choice to obtain stable income through cloud computing power mining
