1063 graphics card digs Ethereum DAG
bitcoin uses SHA-256 encryption algorithm. When mining, it competes with computing power. In order to improve computing power, bitcoin has gone through four stages: CPU mining, GPU mining, FPGA mining and now ASIC mining machine mining, and the degree of specialization is getting higher and higher
Ethereum uses the ethash encryption algorithm. In the process of mining, it needs to read the memory and store the DAG file. Because the bandwidth of each read memory is limited, and the existing computer technology is difficult to have a qualitative breakthrough in this problem, so no matter how to improve the computing efficiency of the computer, the memory read efficiency will not be greatly improved. Therefore, in a sense, Ethereum's ethash encryption algorithm is ASIC resistant.
different encryption algorithms lead to great differences in mining equipment and computing power between bitcoin and Ethereum
at present, bitcoin mining equipment is mainly ASIC mining machine with a very high degree of specialization. The maximum computing power of a single mining machine is 110t / s, and the scale of computing power of the whole network is more than 120eh / s
the main mining equipment of Ethereum is video card miner, and there are very few specialized ASIC miner. On the one hand, the "ASIC resistance" of Ethereum mining algorithm improves the threshold of developing ASIC miner. On the other hand, after Ethereum is upgraded to 2.0, the consensus mechanism will be transformed into POS, and the miner can not continue mining
compared with the ASIC miner, the graphics card miner has two orders of magnitude difference in computing power. At present, the computing power of mainstream graphics card miner (8 cards) is about 420mh / s, and that of Ethereum is about 230th / s.
from the time dimension of the past two years, bitcoin's computing power of the whole network is growing rapidly, while Ethereum's computing power of the whole network is growing relatively slowly
The ASIC mining machine of 
bitcoin is monopolized by several major mining machine manufacturers, and miners can only buy it from the market; Although the graphics card miner of Ethereum is also manufactured by a special miner, the miner can buy accessories from the market and assemble them according to his own demand
politics and English: 50 points. Last year, the first and second districts of the country began to merge, and the score line of these two subjects is unlikely to rise this year. English line is the most concerned problem of many economic examinees. The highest score of this subject in history is 55 points, which appeared in the 11 year postgraate entrance examination. It is very difficult for the line of District 1 to exceed the peak. After all, we have to consider the students of the former District 2. If the national line is set too high, there will be a problem: fewer people can cross the line, which will make many schools dissatisfied with the enrollment. Therefore, I estimate that the score of these two subjects is still 50
Mathematics (professional course 1) + professional course 2:90. In fact, it is not necessary to estimate these two. Basically, these two subjects can't pass the national line or their scores are low, so it's very sad to be in the national line
total score: 335-345. 2011 is a historical peak, 350 points. Last year (2012) was 340. This score is the score line of District 2 in 2011. Therefore, the score may rise this year. We are still considering the situation of the former two districts. Even if the score rises this year, it will not be too high. So the upper limit of 345 comes from this. The lower limit? Because there is a high score base of the original district (i.e. Beijing, Shanghai, Guangzhou, etc.), the decline will not be too much
the above are my predicted scores and predicted results
P.S. I am now a graate student and took the exam last year

generally, high-end and high-performance graphics cards are needed for mining, and mining consumes the performance of graphics cards
-
it is recommended to replace or check the driver version of the graphics card to see if it is the same. If it is still the same, it is recommended to re install the system and use the latest version of win10
