Cyrix Cx486S
The Cx486S is a microprocessor of the 80486 generation from Cyrix ( Cx486 ) and is comparable to the Intel i486SX . Like this one, it does not have a math coprocessor and was therefore marketed as an entry-level model in the 486 generation.
Unlike what is usual at Cyrix, the Cx486S was only sold under its own name.
