Its early CPU products included the 486SLC and 486DLC, released in 1992, which, despite their names, were pin-compatible with the 386SX and DX, respectively. The Cyrix FasMath 82S87, a 80287-compatible chip, was developed from the Cyrix 83D87 and has been available since 1991.Ĭyrix Cx486DRx² Microprocessor. Upon release the 83S87 cost $506 for a 16-MHz version and $556 for a 20-MHz version. Both provided up to 50% more performance, and additionally they had lower power consumption when idle, due to a low power operation. The 83D87 was pin compatible with the Intel 80387, while the 83S87 was pin compatible with the 80387SX. The Cyrix FasMath 83D87 and 83S87 were introduced in November of 1989. The first Cyrix product for the personal computer market was a x87 compatible FPU coprocessor.

Following up shortly after in June of 1992, the Cx486DLC was released, a desktop version of the SLC that was pin-compatible with the 386DX. It was a x86 microprocessor that was pin compatible with the 386SX and made for notebook computer applications. History Īt the end of March in 1992, the Cyrix Cx486SLC was released. National sold the line to AMD in August 2003 where it was known as Geode. National released Cyrix's latest designs under the MediaGX name and then an updated version as Geode in 1999. The combination of these events led Cyrix to begin losing money, and the company merged with National Semiconductor on 11 November 1997. Their release sparked a lengthy series of lawsuits with Intel while their foundry partner IBM was releasing the same designs under their own branding. They were primarily marketed to users looking to upgrade existing machines. These were higher performance than the Intel parts, but lower price. In 1992, Cyrix introduced its own i386 compatible processors, the 486SLC and 486DLC. The company was founded by Tom Brightman and Jerry Rogers. Cyrix Corporation was a microprocessor developer that was founded in 1988 in Richardson, Texas, as a specialist supplier of floating point units for 286 and 386 microprocessors.
