How many calculations per second can an average computer perform today?

<> home computer computing speed calculation method: refers to the number of instructions that can be executed per second, generally described by millions of instructions per second. The same computer may take different amounts of time to perform different calculations, so the speed of the operation is often described in different ways.

The most commonly used is the CPU clock frequency.

Average number of instructions executed per second, etc. For example, 560 megabits per second means that the main frequency of the computer is 560MHz, which means that it can execute 560 million instructions per second. The speed of computer computing is referred to as computing speed.

The number of calculations a computer can perform per second. It is an important indicator of the performance of the computer to measure the amount of slag. Initially, it was expressed in terms of the number of times the addition operation was performed, and later it was expressed in terms of the average speed at which addition, multiplication, division, etc. were performed.

Nowadays, it is common to use the number of times that computers execute various instructions, and then use certain mathematical formulas without worrying about the execution time of each kind of instructions.

Find its average velocity.

to represent.

Born in 1946, ENIAC is a true computing machine that can only perform 300 various operations or 5,000 additions per second. In the following 50 years, the level of computer technology has undergone rapid changes, and the computing speed has become faster and faster, and the number of operations per second has crossed hundreds of millions and trillions of times.

In 2002, NEC built a "Earth Simulator" for the Japan Earth Simulation Center, which can perform nearly 36 trillion floating-point operations per second. Ten years later, on June 18, 2012, the International Supercomputer Organization announced the latest list of the world's top 500 supercomputers, and the American supercomputer regained the first place in the world.

Sequoia's continuous computing test reached 16,324 trillion operations per second, with a peak speed of 20,132 trillion operations per second, which is beyond the reach of other computers.

China's supercomputer, the Tianhe-2 supercomputer system developed by the National Defense University of Science and Technology, is equivalent to 88 years of continuous computing for 1.3 billion people in the country at a peak computing speed of 100 billion times per second. If one day is calculated with "Tianhe-1", a current mainstream microcomputer will be counted as 160 years. The storage capacity of Tianhe-1 is equivalent to the total number of books collected by the libraries of four countries, making it the fastest supercomputer in the world.

The clock frequency of the CPU.

The number of commands executed per second.

Converted according to the maximum computing speed of the CPU, for example, P4 3G, the maximum number of running covers is 3G times per second, which is 3 billion times. That's the speed of computing.

The speed of the CPU is calculated by multiplying the octave size of the CPU by the size of the outer frequency. The external frequency of P4 3G is 866M, and the main frequency is multiple, which is 3031M, which is about equal to 3G

There is a lot of water in this, first of all, not the CPU can achieve the operation every time it runs, sometimes it takes about a dozen runs to complete an operation. Secondly, even if the operation is completed, it does not mean that the operation is completed, and some operations have to wait for a long time before they can be fed back to the large memory. So don't judge whether the CPU is fast just by looking at the computing speed, for example, AMD's CPU computing speed is 2G, which is faster than P4 3G in most cases.

It is said that 1GHz is a billion operations per second, and if your CPU is 2 billion operations per second, there is a lot of water in it, first of all, not the CPU can achieve operations every time it runs, and sometimes it takes about a dozen runs to complete an operation.

For example, if your CPU is clocked at 2GHz, you can compute 2 billion times a second.

This....The speed of computer computing is still accelerating, and it depends on the process of scientific development.

10 10 2 10 3=2 10 (10+3)=2 10 13.

Then the 3rd power of the royal raid work 2 10 can do 2 10 13 times without bending seconds.

2*10 13 (times).

Then talk about the skin work, 2 * 10 3 times slag difference, Liang Kai Fang seconds can do 2 * 10 13 times.

Computing speed refers to the number of instructions that can be executed per second. Now China has developed 2,500 trillion supercomputers, which is equivalent to the amount of 2,500 trillion calculators, because calculators can only be calculated once per second... It is also equivalent to the computing volume of 170,000 notebooks.

How many instructions a computer can process per second.

The computer can calculate several times a second.
