time-to-market by leveraging today’s cost-effective infrastructure to deliver a

superior price/performance PC solution.

To provide state-of-the-art performance, the AMD-K6 processor incorporates the

innovative and efficient RISC86 microarchitecture, a large 64-Kbyte level-one cache

(32-Kbyte dual-ported data cache, 32-Kbyte instruction cache with predecode data), a

powerful IEEE 754-compatible and 854-compatible floating-point execution unit, and

a high-performance multimedia execution unit for executing industry-standard MMX

instructions. These features have been combined to deliver industry leadership in

16-bit and 32-bit performance, providing exceptional performance for both Windows®

95 and Windows NT™ software bases.
