The computer CPU tag in the store analyzes how to distinguish between good and bad

I won't talk about a lot of them, but if you don't know much about computers, I'll tell you just by writing down the model and manufacturer of the CPU you want to look up, such as: AMD 5000+ or Intel E5200 and so on, and then go.

The most basic, the most practical, the simplest! The label is bright and true, and the non-bright is false. Hopefully, o(oThank you!)

You can see if there are many of his bids, and if there are many Taiwan fruits, it means that the CPU has gone through many stores before it comes to you. That's not going to be good.

English refers to the script used by British people (generally American English), and Chinese refers to the script used by Chinese people. ~~

Good or bad. The performance is relatively low.

Basically, there is no problem. After you install the machine, all kinds of games to play.

It's good to be able to light it up. Beware that you may buy fakes, that is, the actual model is not the same as the label printed on the surface of the CPU, and there may be unscrupulous sellers who use low-end to pretend to be high-end CPUs to sell. This is detected with a smaller program called CPU-Z!

Currently, there is no technology that can evade the inspection of the CPU-Z.

You can judge the performance from the parameters of the CPU:

Number of cores: In general, the more cores, the better;

Main frequency: In general, the higher the main frequency, the better;

Turbo frequency, when the computer processes less data, the CPU frequency will automatically decrease, and when the data is processed a lot, the CPU frequency will automatically rise, core

The i5 and i7 support turbo frequency, and some AMD processors also support turbo frequency.

Production process: The production process greatly affects the CPU performance, and the advanced production process is still stronger than the old process even if the number of cores and the main frequency are lower than the old production process, for example.

Pentium Core Bus Interface Type:

pcipci(peripheral

componet

interconnected) bus is Pentium

The component of the PC, the theoretical broadband can reach 132MB s, and usually 95MB s;

PCI-XPCI is an extended architecture of the PC bus, unlike the PCI bus, which must frequently exchange data between the target device and the bus, while PCI-X allows the target device to exchange only a single PCI-X device. The PCI-X is available in three different operating frequencies, 66MHz, 100MHz, and 133MHz, with a data rate of 1Gb S at 66MHz;

PCIEXPRESS, also known as PCI-E, is the next generation of PCI bus, formerly known as "3gio.""It is proposed by Intel, its biggest feature is that the transmission rate is fast, PCI-E has X1, X4, X8, X16, PCI-X1 transmission rate can reach 500MB S, X16 can reach 8GB S;

6.Number of caches: The more cache levels, the better.

A: A large part of the reason why it doesn't light up is the motherboard. If the CPU is used normally, it is rare to encounter a broken one.

It is recommended that you look at the motherboard. And only then pay attention to the CPU.

Of course, the more expensive the CPU, the better...

Configure the CPU, even if you buy a few thousand. But your motherboard, memory and other hardware don't keep up with the same and can't play his normal performance. Therefore, the CPU configuration should be the same as other hardware. so as not to have a bottleneck.!

What is the standard of the landlord's so-called good or bad? Is it speed?

With super

Let's measure 1,000,000 pi.

The less time it takes.

The CPU is also considerably strong.

Use some speed test software, such as the ones that come with Windows Optimizer.

Just don't show it, then it shouldn't be a problem with the CPU. The chances of a CPU breaking are much less than other accessories.

Double-check to see if there is a problem with the graphics card or monitor cable.

Put the CPU on another computer, and you will know the good and bad when you turn it on.

Try it on someone else's computer?

It only takes two steps to distinguish the good and bad CPU, as long as you learn it, you will no longer be afraid of being deceived.

Briefly talk about the general situation: first look at the core architecture and the number of cores. The latest architecture can be understood as the most advanced, the more cores, the better the performance, and of course, the more expensive.

Then look at the L2 cache, the bigger the cache, the better. Then look at the main frequency, the higher the main frequency, the better. For example, Intel, which also uses CPUs of the same architecture, is currently divided into three grades, Celeron, Pentium, Core, low to high.

However, there are differences in performance, such as integrated instruction set, front-side bus, and L2 cache. However, when choosing the Intel CPU of the new architecture, the advantage of high frequency is also obvious. The performance of the Pentium dual-core at the main frequency is very close to that of the slightly lower Core dual-core.

Process improvements are also the main means to improve performance, and mainstream Intel CPUs are also marketed and are usually updated to new processes. In the transition stage, it is necessary to consider options, such as 65nm and 45nm, of course, the performance and heat control of 45nm are improved compared with before.

The two CPUs in hand may be tested using performance testing software, there are many similar software, and a simpler super rabbit can reflect the comparison of the two CPUs. The quality of the CPU is relative, but there are still parameters to compare.

The main aspects are as follows:

1.The number of cores, the current mainstream is dual-core, and the high-end is 4-core;

2.L2 cache, the L2 cache, is currently 1MB or 2MB in the mainstream and 6MB or higher in the high-end;

3.The main frequency, the mainstream is around 2GHz, and the high-end is higher;

4.The production process is 65 nanometers, the old one is generally 90 nanometers, and the latest one is 45 nanometers, the smaller the value, the better.

The more cores, the better, and when the numbers have the same number of digits, the bigger the better.

It depends on what kind of 4 shells you want to buy.
