Computer leisure computing power
at present, the computing power of bitcoin in the whole network has reached 2.36 billion hash collisions per second, which is equivalent to the number of water droplets in more than 200000 50 meter long standard swimming pools. But even with such a large amount of computing power, it will take about 10 minutes to hit a hash value that meets the requirements
in 2012, bitcoin's output was halved for the first time, and in July 2016, bitcoin's output was halved for the second time. At present, 12.5 bitcoins are awarded for recording one page of account book. The next halving will take place around 2020, and the total number of bitcoins will not increase by 2040, with a total of 21 million. In other words, the difficulty of digging bitcoin is increasing, while the time required is increasing
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
2. The computing power of desktop computers using mobile phones requires the support of hardware and software
3. If you are interested, you can study SETI's software and use computer computing resources all over the world to search for aliens
web link post bar example:
we will calculate the graphics card to dig bitcoin earnings
assuming you are HD 7950 awesome, according to Zhongguancun online information, approximately 500MHashs/s
HD 7950 is g to compare the power of the graphics card, calculate 500MHashs/s, converted to 0.5GH/s. I am your current graphics card, you don't need to buy it
the full load power consumption of HD 7950 is 210W, the graphics card mining is full load work, and the electricity charge is 0.6 yuan / kWh
I reckon that you have been digging for 180 days in a row, that is, half a year, 24-hour power on. You should pray that your computer will not hang up because of this
difficulty coefficient: the difficulty of bitcoin has been increasing. Generally, the calculation is increased by 30% in 11 days. I'm a little less. It is increased by 25% in 11 days
OK, all the parameters are ready, calculation
in calculation...
eh, how come it's a negative number
because you need to pay the electricity bill for your graphics card
and there is no bitcoin output every day, because your computing power is too low
suppose your graphics card is HD 7950 and the computing power is 0.5gh/s
at present, 200g ASIC mining machine is on the verge of elimination, because 3T mining machine is already looming in the market
but even the 200 g miner that is going to be eliminated is 4000 times of the 0.5 calculation power of your HD 7950
also playing online games, mobile phones with higher computing power are more fluent, and those with less computing power will get stuck
if you want a mobile phone to have higher computing power and play games without jamming, you need not only more core and higher frequency CPU, but also more memory and more stable and fast network
therefore, network, storage and computing power are the three main factors that determine the computing power of mobile phones. You can go to the tenth power computing platform to learn more about computing power and get free computing power.
for the pressure vacuum gauge, the range should be the sum of positive pressure and negative pressure.
