Advanced Micro Devices 486DX4 Microprocessor

The involvement of semiconductor manufacturer Advanced Micro Devices (AMD) in personal computing spans the entire history of the industry, having supplied every generation of PC processor from the 8088 used in the first IBM PCs to the newer, seventh generation 1.4 GHz clock speed Athlon processor. It wasn't until AMD and its rival Cyrix released their clone versions of the Intel 486DX2 and 486DX4 microprocessors that they really came into their own.
