AMD continues to deliver leading-edge processor solutions by advancing the highly
successful AMD-K6^® processor with state-of-the-art 0.25-micron process technology.
The AMD-developed 0.25-micron process technology enables the AMD-K6 processor
to deliver higher performance with a lower core voltage and lower power dissipation.
This new version of the AMD-K6 processor continues to leverage today’s cost-effective
infrastructure to deliver a superior price/performance PC solution.
To provide industry-leading 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.
