Regarding the processing speed of the computer, the indicators that affect the computing speed of th

1.The same single-core, dual-core CPU is the same efficiency when dealing with single-line components, there is no difference.

But when dual-core, processing two lines at the same time is faster than a single-core CPU, how much faster, 100%??How is it possible Generally 60%.

That is to say, if you use a dual-core CPU to play two games at the same time, the processing power is stronger than that of a single core, if you just do one thing, the frequency is the same, the architecture is the same, and the performance is no different, so the processing of a single thread Single core = dual core, in fact, the speed of dual-core processing of a single thread is not as good as that of a single core with the same frequency, it is said that the application of the dual-core processor on the running platform is not very mature, and Vista is still like this, not to mention XP. The dual-core computer I use doesn't seem to show much of an advantage other than being able to play games while compressing**.

The difference between dual-core and single-core is very clear, and there are many factors that affect the processing speed of the computer, and hardware collocation is a science, and these problems you mentioned are not solved in a few words, but now there are 8 cores, and three cores and four cores have long come out.

Generally, a good CPU needs a large memory, a good graphics card, in fact, the motherboard is the most important, and this platform must be good.

Dual-core technology is to have 2 CPUs working separately, because of this division of labor CPU, the performance will be much more stable and better, so the price will be much more expensive, and there will be 4 cores of CPU soon, so look forward to it!

1. Word length. Generally speaking, a computer processes a set of binary numbers at the same time.

It is called a computer's "word", and the number of bits of this set of binary numbers is the "word length". All other things being equal, the larger the word length, the faster the computer can do it.

Early microcomputers.

The length of the word is generally 8 and 16 bits. Currently 586 (Pentium, Pentium Pro, Pentium, Pentium, Pentium 4

Most of them are 32 bits, and some high-end microcomputers have reached 64 bits.

2. The capacity of the internal memory.

Internal memory, also referred to as main memory.

It is the memory that can be directly accessed by the CPU, and the programs that need to be executed and the data that need to be processed are stored in the main memory, and the size of the memory capacity reflects the ability of the computer to store information in real time.

With the upgrading of operating systems, the continuous enrichment of application software and the continuous expansion of its functions, people's demand for computer memory capacity is also increasing. Currently, Windows XP requires more than 128 MB of memory capacity. The larger the memory capacity, the more powerful the system will be, and the larger the amount of data it can process.

3. The capacity of the external memory.

External memory capacity usually refers to the capacity of hard disks (including internal hard disks and portable hard disks.

The larger the capacity of the external memory, the more information can be stored, and the more application software can be installed. At present, the capacity of hard disks is generally 10 g to 60 g, and some have even reached 120 g.

Modern processors may seem like they can be improved forever, but in reality this is dictated by the laws of physics.

Any computer has limitations. Scientists have discovered that the capabilities of optoelectronic devices are limited by quantum physics itself.

As we all know, nothing is faster than light, and the same is true for electronic systems that use light to control the movement of electric charges. Such a system is called an optoelectronic system and is the fastest in terms of data transmission. And in a new study, scientists from the Planck Institute for Quantum Optics have identified the upper limit of the speed that such a system can reach.

To do this, the authors conducted experiments using semiconductor materials and lasers. In these processes, semiconductors are bombarded with ultra-short buried laser pulses that convert electrons in the material into a higher energy state, removing them from atoms"Strike out"and allow them to move freely within the structure. Then, a second, slightly longer laser pulse sends the particles in a certain direction, creating an electric current.

Using this technique, along with sophisticated computer simulations, the team struck the semiconductor with increasingly short laser pulses. At some point, this process began to conflict with Heisenberg's uncertainty principle – the quantum law, according to which it is impossible to measure a particle's momentum and its position in space at a given time with equal accuracy.

In this case, the use of shorter laser pulses means that the observer can know exactly when the electron is receiving energy, but the amount of this energy is still uncertain. And this is a serious problem for electronic devices, because it is impossible to control them without knowing the exact energy of the electrons.

With this in mind, the team calculated the absolute upper limit of the speed of the optoelectronic system - 1 petahertz, that is, 1 million kilohertz (1015 Hz). This is a hard limit that cannot be bypassed, because this obstacle is embedded in the laws of quantum physics.

In general, the computing speed of a computer depends on the main frequency, and is also related to hardware characteristics such as word length, number of operation bits, number of transmission bits, access speed, number of general-purpose registers, and bus structure. Computing speed is an important performance metric for any computer.

The computing speed is the speed of numerical calculations and information processing by the computer, which is expressed as "times per second". For example, if a certain type of microcomputer has an operation speed of 1 million times per second, it means that this microcomputer can execute 1 million addition instructions in one second.

Nowadays, microcomputers often measure the speed of computing in terms of the main frequency. The microcomputer works according to a fixed beat under the control of the unified clock pulse of Hengqi Fiber. The number of beats per second is called the microcomputer frequency.

It takes about one instruction or a few beats for a microcomputer to execute an instruction. The higher the frequency, the shorter the time to execute the instruction and the faster the operation speed.

I chose D. It is converted according to the maximum computing speed of the CPU, such as P4 3G, which can run up to 3G times per second, which is 3 billion times. That's the speed of computing.

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

There is a lot of water in this, first of all, not the CPU can realize the operation of the local situation every time it runs, and 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 a long time before they can be fed back to memory. So don't just look at the calculation speed to determine whether the CPU is fast, for example, AMD's CPU speed is 2G, which is faster than P4 3G in most cases.

Cycle to do i--; 1 billion times is about seconds.

10 0000 0000 one time minus 1 billion times to 0).

There is also a state with other windows open, the CPU frequency state, and the CPU load is 12%.

Close i--; After that, the CPU status is 1GHz, the load is 2%, that is, the CPU does 1 billion times minus 10% in about a second time, and the CPU occupies 10%, and the above should be about the same as what I personally did.
