Faster
It's competitive with Pentium Pro and outperforms the latest PC processors equipped with multimedia extensions (MMX).

More Advanced
The AMD-K6 is based on AMD's six issue RISC86® superscalar microarchitecture and provides the most advanced Windows-compatible processor available. -The AMD-K6 also features high performance, industry standard MMX to accelerate multimedia applications.

Easier to use
AMD designed the AMD-K6 processor to fit the low cost, high volume Socket 7 infrastracture. This provides an easier upgrade path to future members of the high performance AMD-K6 processors.

More affordable
The AMD-K6 processor provides sixth generation performance at mainstream prices.
