Cyrix Cx486
The Cyrix Cx486SLC is a x86 microprocessor that was developed by Cyrix. It was one of Cyrix's first CPU offerings, released after years of selling math coprocessors that competed with Intel's units and offered better performance at a comparable or lower price. It was announced in March of 1992,[1] and released 2 months later in May, with a price of $119.[2] It was priced competitively against the Intel 486SX, causing Intel to lower the price of their chip from $286 to $119 in just days.[3]
