Cyrix 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.
