Ethernet computing power of video card
Graphics cards can't dig out bitcoin right now. Your calculation power is the calculation power of Ethereum. The calculation method is also wrong
1. Power consumption: 243w; Calculation force: 22.4m; Price: 1999 yuan; The number of eth g every 24 hours: 0.015; Revenue generated every 24 hours: 24.8 yuan; Expected payback time: 81.66 days
2. Power consumption of the whole machine: 159w; Calculation force: 24.3m; Price: 1599 yuan; Number of eth g every 24 hours: 0.017; Revenue generated every 24 hours: 27.9 yuan; Expected payback time: 57.31 days
3. Power consumption: 171w; Calculation force: 24.4m; Revenue generated every 24 hours: 27.87 yuan; Expected payback time: 71.73 days
4. Power consumption: 97W; Calculation force: 9.2; Price: 999 yuan; Number of eth g every 24 hours: 0.006; Revenue generated every 24 hours: 10.09 yuan; Expected payback time: 99.1 days

mining machine risk
1. The problem of electricity charge
in order to make the graphics card full load for a long time, the power consumption will be quite high, and the electricity charge will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned
2. Hardware expenditure
mining is actually a competition of performance and equipment. Some mining machines are composed of more such graphics card arrays. 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
3, currency security
the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but the frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin
2. The content of the examination includes the following aspects:
maternal care: prenatal care, breast care, puerperal care, breastfeeding guidance, postpartum meal proction, postpartum gymnastics and psychological guidance
infant care: feeding the newborn, nursing the newborn's skin, nursing the newborn's facial features, bathing the newborn, disinfecting the newborn's umbilical cord, changing diapers and clothes for the newborn, guiding the newborn's sleep, etc
infant nutrition nursing: nutrition knowledge of newborn, method and time of adding complementary food, proction of complementary food of newborn, etc
3. After the examination, you wait to pass the examination of the labor department, and finally you can get the Yuesao certificate by issuing the certificate<

Radon is a series of display chips proced by AMD company, commonly known as a card
the full name is generally written as: AMD radon HD XXX, for example, the model of desktop graphics card is amd radon HD 6450. After hd7000 series, AMD will use new amd radon R9 / R7 XXX to name its new display chip
today's amd proct portfolio has an unprecedented power saving capability. The sharp dragon desktop processor based on Zen architecture has strong performance, and its power consumption is as low as 65W, which has never been seen before. However, with the Polaris architecture and 14nm process, the power control of the video card of the radon RX 500 series is much better than that of the previous generation
at present, the desktop graphics cards of AMD's radon series are:
AMD's radon R9 / R7 300 series / fury Series graphics cards
AMD's radon RX 500 Series graphics cards and radon's RX Vega
AMD's radon HD 7000 Series graphics cards

the difference between a card and N card
I Concept analysis:
1. A card: in the early stage, it was a graphics card using ATI graphics chip. At present, ATI has been acquired by AMD. A card is called amd graphics card, and a card works in radium and X series. A card focuses on 2D graphic quality
2. N card: it is a graphics card with NVIDIA graphics chip. N card works include geforce (GTX) series, geforce FX (GT) series, etc. N card focuses on 3D performance and speed
Advantages: each stream processor in n card's GPU has a complete Alu (arithmetic logic unit) function. When an operation instruction is issued, each stream processor can work fully. The frequency of the graphics card can reach nearly 100%disadvantage: high power consumption
2, a card:
advantage: ATI's design also has its remarkable feature - powerful floating-point computing power. In other words, if the display core's ability in floating-point operation is simply compared, ATI may be better. In terms of scientific computing, which is widely used in GPGPU (general graphics processor) projects, ATI can theoretically adapt to the trend of GPU and CPU platforms
disadvantage: software optimization is not enough
