480 graphics card computing power

1.

21.5 * 3600 seconds * 24 hours = 1857600 M / day
1857600 / 1024 / 1024 = 1.7715 T / day
a t of computing power / day can dig bitcoin worth 4.03 yuan
1.7715 * 4.03 = 7.14 yuan / day

since 2017, bitcoin has reached new heights. Yesterday (May 23), the value of bitcoin broke through the ￥ 16000 mark, hyping virtual currency, becoming a matter that the general public can participate in, And a little bit of technical level, both fried money, but also began to have the technical content of mining

as we all know, virtual currency has a numerical peak, the more difficult it is to dig. In fact, it's hard to judge whether to lose money or not if we continue to dig. Therefore, in the end how to dig, dig what can be the fastest back to this, this paper studies the above two core issues based on the current market situation

3. 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:
power consumption: 243w
computing power: 22.4m
price of graphics card: 1999 yuan
number of eth g every 24 hours: 0.015
revenue generated every 24 hours: 24.48 yuan
expected payback time: 81.66 days
power consumption: 159w
computing power: 24.3m
price of graphics card: 1599 yuan
price of graphics card: 1599 yuan
every 24 hours Number of time digging eth: 0.017
revenue generated every 24 hours: 27.9 yuan
expected payback time: 57.31 days
video card of radon RX 480

4. 1. According to the mining software, the larger the value, the faster the "speed" in the software

2. Different mining softwares have different algorithms and ranking.

5. thirty

6. According to a certain software, the value is tested. The larger the value is, the faster the speed will be in the software
it is common in mining software, but the ranking will be different for different algorithms.

7. 1. R470-jt01 has been on the market for some time. The minimum price we need here is 5800 yuan
2. The graphics card of r518 is ATI
mobility
radon
HD4650
GDDR3
1g video memory
the graphics card of R470 is NVIDIA
geforce
g210m
GDDR3
512M video memory
3. I don't know whether you mean notebook or graphics card. I guess you should pay more attention to the battery life, So when you ask this question, generally speaking, a 15.6-inch notebook costs more electricity than a 14.1-inch notebook
4. Different cities have different prices. The lowest price of r518 here is 5600 yuan
in order to facilitate your choice, I will tell you two differences, that is, in addition to the difference between the graphics card and the video memory and the operating system, there are also differences in the number of USB interfaces: R470 is 3, r518 is 4
in the end, I don't know whether you are looking at dd02 or ds03 of r518. If it is ds03, there is another difference: ds03 doesn't have Bluetooth
I hope I can help you. If you have any questions, please ask me directly.

8. A. When chemical reaction occurs, the more metal atoms lose electrons, the stronger rection ability is not necessarily. For example, the property of gold: magnesium > aluminum, so a is wrong
B. the rection of metal cations does not necessarily lead to the formation of metal elements. For example, iron ions are reced to ferrous ions, so B is correct
particles with the same number of protons, such as water and neon, are not necessarily atoms of the same element, so C is wrong
D and sodium peroxide can only react with acid, belonging to peroxide, not alkaline oxide, so D is wrong.
b is selected

9. APU series no matter which one can't compare with i5 4590, APU series focuses on strong performance. You should compare the fx8300 to the i5 4590. That's the same level
