AMD-K6® Processor Data Sheet

Preliminary Information

The AMD-K6 processor’s RISC86 microarchitecture is a decoupled decode/execution

superscalar design that implements state-of-the-art design techniques to achieve

leading-edge performance. Advanced design techniques implemented in the AMD-K6

include multiple x86 instruction decode, single-clock internal RISC operations, seven

execution units that support superscalar operation, out-of-order execution, data

forwarding, speculative execution, and register renaming. In addition, the processor

supports the industry’s most advanced branch prediction logic by implementing an

8192-entry branch history table, the industry’s only branch target cache, and a return

address stack, which combine to deliver better than a 95% prediction rate. These

design techniques enable the AMD-K6 processor to issue, execute, and retire

multiple x86 instructions per clock, resulting in excellent scaleable performance.

The AMD-K6 processor is fully x86 binary code compatible. AMD’s extensive

experience through four generations of x86 processors has been carefully integrated

into the AMD-K6 to provide complete compatibility with Windows 95, Windows 3.x,

Windows NT, DOS, OS/2, Unix, Solaris, NetWare®, Vines, and other leading x86

operating systems and applications. The AMD-K6 processor is Socket 7 compatible,

allowing the processor to be quickly and easily integrated into a mature and

cost-effective industry-standard infrastructure of motherboards, chipsets, power

supplies, and thermal designs.

AMD has designed, manufactured, and delivered over 50 million Microsoft®

Windows-compatible processors in the last five years alone. The AMD-K6 processor is

the next generation in this long line of processors. With its combination of

state-of-the-art features, industry-leading performance, high-performance

multimedia engine, full x86 compatibility, and low-cost infrastructure, the AMD-K6 is

the superior choice for mainstream personal computers.
