Cyrix 5x86

The Cyrix 5x86 is a line of x86microprocessors designed by Cyrix and released on June 5, 1995. Cyrix, being a fabless company, had the chips manufactured by IBM. The line came out about 5 months before the more famous Cyrix 6x86. The Cyrix5x86 was one of the fastest CPUs ever produced for Socket 3computer systems. With better performance in most applications than an IntelPentium processor at 75 MHz, the Cyrix Cx5x86 filled a gap by providing a medium-performance processor option for 486 Socket 3 motherboards (which are incapable of handling Intel's Pentium CPUs, apart from the Pentium Overdrive).

The IBM 5x86C is an IBM branded and produced version of the Cyrix-designed Cyrix Cx5x86 CPU. Previous IBM x86 processors, IBM 386SLC and IBM 486SLC, were based on modified Intel designs.
