Collecting basic knowledge of CPU needs to be easy to understand and learn.

I saw other people's introductions on the Internet and thought they should be useful to you. I would like to share them with you:

AMD has good game performance and strong overclocking ability ~ ~ ~

INTER has a low calorific value.

AMD's L2 cache is small, but it is very cost-effective.

AMD's floating-point computing ability is stronger, which is suitable for games and logic processing.

The design of Intel is relatively better.

At present, the differences between INTEL's CPU and AMD's CPU, and the differences in performance and efficiency caused by the differences are as follows, for reference only:

1。 From monocrystalline silicon technology: Intel: 0. 09 (reducing costs and increasing the number of transistors), AMD: 0. 13 (cost ratio 0. 09), so Intel will still make money after the same price reduction, while AMD will at least not make too much money, and may even accompany the money (loss), although the market share has increased, which led to the recent AMD lawsuit.

2。 From the assembly line: Intel: 3 1 (it can be upgraded to a higher main frequency, but it will bring more heat: for example, P4-670 exceeds 7. 4G, but using liquid nitrogen to dissipate heat is easy to cause inefficient instruction execution, so a hyper-threading is made to make up for it); AMD: Grade 20 (instruction execution efficiency is better than 3 1 grade, but the frequency increase is limited and the calorific value is relatively low. Efficiency and frequency are two different development directions, mainly depending on the user's choice).

3。 Cache: Intel: 1 level 16K, level 2 1M-2M (integer operation and game performance are not as fast as AMD (there is another main reason to work, which will be discussed later), but it is better than competitors in network and multimedia (floating-point operation) applications.

AMD: 1 level 1 128K, level 2: 5 12K (fast integer operation, good game performance, but slightly inferior to multimedia applications).

4。 Memory management shelf is enough: INTEL's memory management shelf is still managed by the traditional way of north-south bridge on the motherboard (resulting in a large delay in data transmission between CPU and memory, which is not as good as AMD's for game execution, but will reduce the upgrade cost in the future). AMD is an integrated memory controller in CPU (reducing the delay of data transmission between CPU and memory, which plays a considerable role in improving game performance, is also the main reason mentioned above, and also makes up for the shortage of level 2 multimedia applications, only 5 12K, but it increases the cost of future upgrades: if you want to upgrade, you have to replace all CPU, memory and motherboard).

5。 Instruction set Intel: MMX, SSE, SSE2, SSE3, EM64T.

(Most games and software are based on INTEL's instructions and optimized for INTEL, but 64-bit instructions have the disadvantage of being compatible with new 64-bit systems, so they have to be compatible with AMD's X86-64 instructions recently, and the stepping value of CPU has changed from E0 to G 1) AMD: 3DNOW+, MMX, SSE, SSE2, SSE3, X86-64 (supported SSE). Because AMD's 64-bit technology originated from DEC's Alpha technology (one of 64-bit technologies) and AMD's own secondary development, 64-bit technology quickly appeared in the civilian market. Microsoft's 64-bit system also had to be developed based on AMD's X86-64-bit (who told AMD to launch civil 64-bit first? ). In order to eliminate the compatibility problem of 64-bit WINDOWS as soon as possible, Intel was forced to start to be compatible with AMD's 64-bit instructions.
