List of AMD K5 processors explained

The AMD K5 microprocessor is a Pentium-class 32-bit CPU manufactured by American company Advanced Micro Devices (AMD), and targeted at the consumer market. It was the first x86 processor designed by AMD from the ground up, and not licensed or reverse-engineered as previous generations of x86 processors produced by AMD.^[1] ^[2] ^[3]
