Stealing CPU computing power
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
the daily cash withdrawal limit of ATM is 20000 automatic teller machine, also known as ATM, is the abbreviation of automatic teller machine, which means automatic teller machine. Because most of it is used for withdrawal, it is also known as ATM. It is a highly precise mechatronics device, using magnetic code card or smart card to achieve self-service of financial transactions, instead of the work of bank counter staff. It can withdraw cash, inquire deposit balance, transfer funds between accounts, inquire balance, etc; It can also carry out cash deposit (real-time entry), check deposit (none in China), passbook re registration, intermediate business, etc. Cardholders can use a credit card or savings card to make automatic withdrawal, balance inquiry, transfer, cash deposit, passbook re registration, purchase funds, change passwords, and pay mobile phone bills according to their passwords
different ATM settings are different, some are single transaction 2000, some are 2500, 3000, at most 5000 per transaction; At the time of withdrawal, ATM will prompt the maximum amount of each withdrawal
Data: the physical symbols or the combination of these physical symbols that record the nature, state and relationship of objective things, also include numerical data and non numerical data
information is another form of data after data processing, which affects the behavior of the receiver to some extent. It has objectivity, subjectivity and usefulness
The relationship between data and information: information is the meaning of data and data is the carrier of information 
data are numerical values, that is, the results obtained by observation, experiment or calculation. There are many kinds of data, the simplest of which is numbers. Data can also be text, image, sound, etc. Data can be used for scientific research, design, verification, etc
information refers to the objects transmitted and processed by audio, message and communication systems, and generally refers to all the contents transmitted by human society. By obtaining and identifying different information of nature and society, people can distinguish different things and understand and transform the world. In all communication and control systems, information is a form of universal connection
In 1948, the mathematician Shannon pointed out in his paper entitled "mathematical theory of communication" that "information is used to eliminate random uncertainty". Information is the most basic universal unit to create all things in the universequantity * dominant frequency is wrong.
first of all, the CPU of home computer can see the floating-point operation, just download the corresponding software to test the floating-point operation of CPU, single precision / double precision and so on
secondly, floating-point operation only shows the performance of household CPUs. On the one hand, some CPUs are too high to reflect your daily application
for example, compared with the old core architecture, the new core architecture with fewer cores has lower total score, but stronger single core performance.
