The 32-bit microprocessor K6 of the sixth microprocessor generation from Advanced Micro Devices (AMD), was first introduced in 1997 and further developed in the following years in the versions K6-2 and K6-3. The K6 is compatible with the Pentium II and MMX, but superior to them in certain characteristics.
The first version had a clock frequency of 233 MHz, which was later increased to 300 MHz. In terms of technology, the K6, like its predecessor K5 and successor K7, represents CMOS technology with an integration density of 8.8 (9.3) million transistors and a structure track width of 0.25 µm; initially 0.35 µm. The level 1 cache is 64 kilobytes( KB) in size, increasing processing speed.
The RISC concept of the K6 converts xx86 instructions into RISC operations, which further increases execution speed.
The K6-2 version features clock speeds of 333 MHz and 400 MHz and improved performance features. It has a multimedia instruction set, 3DNow, including 21 instructions for 3D graphics, and is suitable for front side buses at 100-MHz.
The K6-3 version has 21.3 million transistors and 500-MHz clock speed and a 2- megabyte( MB) Level 2 cache.
