CPU computing power improvement

1. 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

2. The main frequency of CPU determines its maximum computing power per second, that is, its computing speed
some CPUs have two levels of flash memory. The speed of data exchange between flash memory and CPU is very close to that of CPU itself
in general, the data exchange between memory and CPU is one or two orders of magnitude lower than the computing speed of CPU itself (depending on which bus the computer uses), which is the biggest bottleneck affecting the overall computing speed of a computer
so your question is not completely correct. The relationship between the overall computing power and memory size of the computer and the relationship between the overall computing power of the computer and the data exchange speed of the bus are secondary
only when the bus speed is constant and the size of memory is not less than the maximum number of bytes that can be exchanged by the bus per second, can the memory not become a factor to rece the overall computing speed of the computer
I don't know if you are satisfied with this answer.

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. CPU frequency is actually a camouflage data, the previous Pentium 4 is an example, single core high frequency, energy consumption Tiankeng! Multi core processing is now the king, multi task processing capacity, with graphics card GPU auxiliary, 22nm, 32nm, 45nm process, represents the potential of energy saving and performance. CPU's two-level cache and three-level cache represent the opening ability of high-speed channels. In the case of high computing power and low channel, what level can't be reached? Lga1355 and other architectures represent the foresight of the whole CPU, and the computing power is not frequency visible.... High frequency, can only say that the front-end appearance is good, depends on the number of cores, technology level and two or three level cache to see if it is enough, you did not say a few cores, let alone what model, this is not the standard! There is no answer to this question!

5. 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.

6. 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.
