As the next generation in the AMD K86™ family of x86 processors, the innovative
AMD-K6 processor brings industry-leading performance to PC systems running the
extensive installed base of x86 software. In addition, its socket 7 compatible, 321-pin
Ceramic Pin Grid Array (CPGA) package enables the AMD-K6 to reduce
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.
