CPU computing power query

1. 1. The meaning of CPU calculation once is that CPU performs "bit calculation" once, for example, 2 + 3 = 5, and binary is 0010 + 0011 = 0101. If there are three bits in total, the computer will calculate three times. 2. As for what this number is related to, that is, the higher the CPU frequency, the more the number of operations per unit time

2. The computing power of CPU is related to the number of CPU cores, the frequency of core and the ability of single clock cycle of core
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

3. I54590 is a four core, four thread, three-level cache is 6MB. The i7 4790 is a 4-core 8-thread, 3-level cache of 8MB. CPU is not only determined by the dominant frequency.

4. No, if multiple programs are running at the same time, the al core 2.2g is better than the single core 4.4g. If it is a single task, the 4.4g single core is certainly better. Now u is developing towards multi task operation. For example, if you watch a movie with 4.4g, it's no problem. If you open a few web pages or games at the same time, the cup will happen, but the al core 2.2g is different.

5. In theory, the computing power of a computer is only related to the processor. The better the processor, the higher the computing power. The more powerful a computer is, the faster it can deal with problems. For a simple example, suppose I open a small supermarket by myself. After a year, all the costs and losses of my supermarket are recorded in the computer. After a year, I need to count the accounts to see how much money I make in a year and what's wasted. Then the stronger the computer's computing power is, the faster your speed will be. Because after a year, you have too many broken accounts every day, and the computing power of the computer processor is poor. The longer you spend, and even the computer is stuck for several days. This is the most intuitive solution to the problem of computing power. Secondly, according to the current computing power of computers, quantum computers have the strongest computing power. All computers work by "algorithm" to calculate what we need. Ordinary computers work by "binary" calculation, that is, "bit & quot;, People who have studied computer know that a character in a computer is called 8 bytes (8bit). Let's assume that if I need to crack a password, it is assumed that it is 10 digits. Now, the password cracking technology is all based on the password dictionary technology (none of which is used), that is, the computer arranges 10 digits in turn. If the order is right, then the password will be solved. Well, you can calculate that the 10 digit password is nearly 1 billion. How long does it take for the computer to calculate? At this time, the computer's strong computing power will come out. The ordinary computer may take several days, and the quantum computer with the strongest computing power in the world may only take one second. In addition, we need to understand that computer computing power does not represent everything, which is determined by a lot of hardware. Processor, motherboard, memory and many other things together.

6. If the program has been optimized for multi-core, that is to say, the multi-core CPU can also play its advantages. It is recommended to take a look at Lenovo's X6 server (the original IBMX Series), which can host four physical CPUs with strong performance.

7. E-cash can only be consumed by flash payment, so you can ask the local ICBC where there is a POS machine supporting flash payment, go to some cooperative merchants of ICBC, and support chip card consumption. We can do things like noodle king and Baiguoyuan. I don't know if you can do it. If you don't have it, you can only cancel the card. You need to withdraw the money from it
