Cyrix 6x86 processor is a x86 compatible superscalar microprocessor with 64-bit internal architecture, 80-bit Floating Point Unit, 16 KB write-back cache, speculative execution, branch prediction and other advanced features.

There were three different versions of the 6x86 CPU:

• 6x86 - Original single-voltage version.
• 6X86L - Low-power version of 6x86 CPU with split core and I/O voltage.
• 6x86MX - 6x86 microprocessor with advanced MMX instruction set, split core and I/O voltage and larger level 1 cache.

All Cyrix 6x86 processors used Pentium Rating (PR).
