3090 double precision force calculation
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
Gtx960 can dig, but its computing performance is very poor. The single precision is only 2.6t, and the double precision is 1 / 32 of the single precision, so the efficiency is too low
the full load operation of two gtx960s is not as efficient as AMD's one rx480, and the two 960s have the same computing power and higher power consumption
the performance of gtx960 is the same as that of gtx1050ti, and there is not much difference in mining computing power. N-card computing is different from a-card computing. Amd graphics card is used for mining, while r9380 is several times slower for gtx960 mining
extended data
gtx960 graphics card mining is not very cost-effective, mining card is rare, generally a card mining, n card is rare, no matter how much money is not recommended to buy
The performance of gtx960 and gtx1050ti are at the same level, but these two types of graphics cards are not in the range of mine cards, because the computing performance of 1050ti and 960 can not meet the mining requirements, or they may not be able to mine in half a year. Generally, mine cards are made of rx470, 480, 570, 580 or gtx1060 middle end graphics cards, as well as high-end onesthe performance of the graphics card is determined by the hardware specifications of the card itself. No matter what optimization and setting tools are used, there will be no substantial change. If the game has high requirements for graphics card, and gtx960 can not meet the requirements, then the most effective way is to rece the resolution and special effects settings, and the fluency will certainly be improved
The double precision values of 480 and 580 are basically the same, which are 1 / 16 of the single precision, about 360gflops. In fact, these two cards are not easy to use. The double precision of 280x is three times that of this, about 1000gflops
the ability of double precision floating-point computing is commonly used to measure the scientific computing ability of CPU, that is, the ability to process 64 bit floating-point data
the processor supporting avx2 can perform 16 floating-point operations in one core and one clock cycle, Also known as 16flops
CPU power = number of cores x frequency of cores x 16flops
processors supporting avx512 can perform 32 floating-point operations in one core and one clock cycle, also known as 32flops
CPU power = number of cores x frequency of cores x 32flops
According to the current computing power of the whole network, it takes 54436.5t of computing power to dig a bitcoin 24 hours, that is, one bitcoin a day< it requires 746 mining machines with the latest 73t capacity on the market to work together for 24 hours
the cost of mining mainly includes (mining machine cost / power cost). Now the latest miner is 22650 yuan, a miner consumes 77 kwh per day. At present, the price of mining machinery on the market is about 0.36 yuan, 28 yuan per day. The cost of mining bitcoin = mining machine price (22650)
mining bitcoin requires a professional site "mine" to place mining machines. The construction cost of placing about 3000 mining machines in a small professional mine is about 300 watts
extended data
unable to mine at home
the noise of 60-80 decibels will be proced by the mining machine in the working process. Mining at home is not feasible, the miner needs 24 hours of endless operation, so the temperature of the miner will be very high, the maximum temperature can reach 80 degrees. Therefore, mining needs a good environment to rece the temperature. Household electricity and electricity charges are high, and the cost is higher than the income. In addition, mining has a certain degree of professionalism, professionals need to carry out certain operation and maintenance to ensure the normal operation of the mining machine
the key to rece the mining cost is to purchase mining machines in batches and low electricity charges. Professional mine is built to ensure the operation of mining machinery. At present, the mainstream mining machinery manufacturers are bitcontinental Technology Co., Ltd. in Beijing and Jianan Yun Technology Co., Ltd. in Hangzhou. Mining machinery is proced in the form of appointment in futures. It is difficult for indivials to buy Mining machinery in small quantities on the official website. After years of development, the mining machinery market has formed a complete instrial chain. The price of mining machinery fluctuates with the price of money, and the power resources are basically distributed in the cheap western region. Getting cheap electricity prices requires personal resource advantages
