The difference between Intel CPU and AMD and the mainstream models

Intel mainstream models include i3, i5, i7 and i9 AMD mainstream models, including sempron, Athlon and phenom.

First of all, the CPU pipeline is different

1, Intel: There are ten stages in the CPU pipeline. Take instruction 1, take instruction 2, decode instruction 1, decode instruction 2, calculate operands, schedule operations, confirm and execute instructions, and store them in cache 1 and cache 2.

2. AMD: The CPU pipeline has only five levels. Extract instructions, decode instructions, calculate operands, execute instructions, and store them in the cache.

Second, the degree of firmness is different.

1, Intel: We will adopt the method of "stretching the assembly line". Due to the protection of the top cover, viscous silicone grease will not be brought down due to heat dissipation.

2.AMD: When removing the radiator, AMD's CPU is likely to be stuck by silicone grease and fall off from the socket. The main frequency of the processor depends on the execution time of each stage pipeline, and has nothing to do with the execution efficiency.

Third, the packaging methods are different.

1, Intel: It is packaged by LGA. There are no pins on the CPU.

2.AMD: Socket-TR4 package is adopted. There are pins on CPU.
