When buying a CPU, what are the main parameters?

Upstairs, you don't know how to pretend to understand, I've been repairing the computer for 2 years, and I've never seen it explained like that, this brother, let me tell you how to look at it, when you buy a CPU, you can see it when you open the package, and it is written on the front of the CPU, I'll give you an example, the CPU you bought is the CPU described like this, the 2M represents the 2M cache, and the 400 behind represents the frequency.

Main frequency, external frequency, voltage. The main frequency is enough to do everything!

I can't seem to see it myself, so I have to use software to check it, such as cpu-z

The CPU of each computer depends on the cache, external frequency, main frequency, and hertz. When you ask him about a computer, he will tell you the configuration. Of course, the higher the better

1. Press the Ctrl+Alt+Del keys at the same time to open the operation interface of "Task Manager", and then click the "Details" option.

2. Then in the interface that opens, then click on the "Performance" option.

3. Click the "CPU" option below, and then you can see the performance parameters of the CPU.

<>2. Next, select the "Toolbox" option in the lower left corner of the housekeeper interface;

3. Next, select the "Hardware Detection" option in the toolbox interface;

4. Next, select the "Electrodispersion Brain Overview" option on the hardware detection interface;

5. Next, select the "CPU Signal Rush Slag" option in the computer overview interface;

6. Next, you can see the CPU parameter guess in the CPU information interface;

The role of the CPU and its main performance indicators.

1) The CPU is the core component of the computer. It is divided into: arithmetic unit, control unit, and storage unit.

2) Performance indicators.

0 1 Clock frequency, the higher the frequency, the faster the speed. Main frequency = outer frequency x frequency multiplication.

0 1 Memory bus speed Also known as system bus speed, it is generally equal to the external frequency, which refers to the working frequency between the CPU and L2 (L2 cache) and memory.

0 1 Working voltage The CPU manufacturing process and the main frequency increase, and the working voltage decreases.

0 1 CPU Extension Instruction Intel-SSE, MMX AMD—3D Now

0 1 Integer, floating-point Integer arithmetic exists in large office software, and floating-point arithmetic mainly exists in games and graphics software.

0 1 L1, L2 L1 - L1 - L1 cache, consisting of static RAM.

L2-L2 cache to compensate for the huge speed difference between the CPU and other components. Performance parameters that are important when buying a CPU.

L1 caching, L2 caching, and architecture!

There are several views on buying a CPU, each of which is different. But each of them is very effective.

The first CPU brand, the current brand is nothing more than two AMD and Intel, at present, Intel's technology is above AMD, so AMD leads part of the market with cost performance, low **, high performance. Intel is like an Apple mobile phone, leading most of the market with high performance, high-end, and low power consumption. In terms of price/performance, AMD is more powerful.

In terms of performance, Intel is much higher than AMD, but it has lower heat and higher performance.

The second way is to look at the structure at a glance. It's hard to understand what a framework is, but it's actually very simple, I just said simply, the newer the architecture, the stronger the ability, the architecture is many years before a new architecture comes out, and this new architecture will be used all these years. For example, the future structure is the Sky Lake Framework, Skylake.

The third type of brand structure is not yet available, so let's look at the simpler ones. performance, at the moment, is at least greater than. The number of cores is currently 2 cores of hyperthreading, and at least 4 cores are required without hyperthreading.

The lower the nanometer, the better, the nanometer should be at least 32 nanometers or the minimum should not be greater than 45 nanometers, and the heating of 45 nanometers is already a bit high.

Fourth, depending on the model, AMD and Intel models are not the same. I won't go into detail about the model, because this score can give you two or three articles to come out, because the naming is so many and cumbersome, you can find the two of them on the Internet. It's too much, you won't watch it if I hit you.

Let's talk about it in detail: Intel's words look at the i-series i3 medium users i5 advanced users i7 game-level users. Intel doesn't have low-level users, because their Intel CPUs are very high, and the lowest ones are like mid-to-high users.

AMD, the Dragon series is endangered, and there are still Athlon and Athlon II. The rest are the FX and A-series. Athlon X4 is a high user, FX is a bulldozer series, and the appearance attributes are very strong, but it just can't do intel.

Targeting is also at the game user level. The A series, which belongs to the advanced users, has a performance similar to that of the Athlonx X4. In fact, the performance is similar to that of the Athlon X4.

AMD** is cheap and has high performance, and Intel** is also very high-performance. However, Intel's motherboards are also expensive, and that's the disadvantage.
