Intel s CPU and all motherboards are not universal. AMD s.

1, Intel's CPU is not universal, Intel is divided into LGA775 1155 1156, etc., basically can not be replaced; AMD is divided into AM2, AM3, AM2+ FM1, etc., and some of them can be used interchangeably by flashing the motherboard BIOS.

AMD's is like this, as long as the CPU and motherboard CPU interface are the same, it can be used. Intel.

The same can be said for the two years, but not for the 775 interface, such as the early 915 and 945 chipsets.

Although it is also a 775 interface, it cannot be on the quad-core 775 interface CPU, and the 915 does not support the full range of Core 2CPUs

No, there are 2 types of motherboards, AMD motherboards and Intel motherboards, which are not compatible with each other, their interfaces are different, so they cannot be universal, that is, a motherboard can only use one manufacturer's CPU

Basically, it can be understood in this way, as long as the CPU from the same company has the same number of pins and contacts, it can be used on the same pin base. At present, Intel has 775 pins, 1155 pins, 1156 pins and 1366 pins on the market, and with the increase in the number of integrated transistors, the number of pins is also increasing. AMD's is the same, as long as the number of pins is the same, it can be used universally.

However, to separate AM2 and AM3, AM2 cannot support DDR3 memory.

IBM, IDT, VIA, domestic Loongson.

1: IBM and Cyrix, after the merger of IBM and Cyrix, the national semiconductor company of the United States, it finally has its own chip production line, and its finished products will be increasingly perfect and complete. The current MII performance is also good, especially since it's very low.

2: IDT is committed to providing application-specific communication integrated circuit products for promoting intelligent packet processing in global networks. IDT provides solutions for edge, core edge, network access points, enterprise, small office home (SOHO), data center, and wireless networks to meet the rapidly growing demand for intelligent packet processing.

3: Athlons are AMD's family of processors for the mainstream market. There are K8 and K10 architectures, and the process is 90nm, 65nm, and 45nm.

The products involve dual-core, triple-core and quad-core. In the K8 era, Athlons were the main force of AMD, and after K10, Athlon took over the banner, and Athlons began to face the mainstream market. Athlons have a lower price than Eulon **, so they are favored by many consumers.

4: Loongson is a general-purpose CPU independently developed by the Institute of Computing of the Chinese Academy of Sciences, using RISC instruction set, similar to MIPS instruction set. The frequency of Loongson 1 is 266M Hz, which was first used in 2002.

Loongson 2 has a frequency of up to 1GHz. Loongson 3A is the first domestically produced commercial 4-core processor, which operates at 900MHz 1GHz.

5: The peak computing power of Loongson 3A reaches 16Gflops, and Loongson 3B is the first domestic commercial 8-core processor, with a main frequency of 1GHz, supports vector operation acceleration, and the peak computing capacity reaches 128 Gflops, with a high performance-per-watt ratio.
