Cyrix 6x86
6x86
<processor> (6x86) {IBM} and {Cyrix}'s {sixth-generation},
64-bit {80x86}-compatible {microprocessor}. The 6x86 combines
aspects of both {RISC} and {CISC}. It has a {superscalar},
{superpipelined} {core}, and performs {register renaming},
{speculative execution}, {out-of-order completion}, and {data
dependency removal}. It has a 16-kilobyte {primary cache} and
is socket-compatible with the {Pentium} P54C. It has four
performance levels: PR 120+, PR 150+, PR 166+ and PR 200+.
The chip was designed by Cyrix and is manufactured by IBM.
The architecture of the 6x86 is more advanced than that of the
Pentium, incorporating some of the features of Intel's
{Pentium Pro}. At a given {clock rate} it executes most code
more quickly than a Pentium would. However, its {FPU} is
considerably less efficient than Intel's.
