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. The company was founded by Tom Brightman and Jerry Rogers.
In 1992, Cyrix introduced its own i386 compatible processors, the 486SLC and 486DLC.[2] These had higher performance than the Intel parts, but a lower price.[3][4] They were primarily marketed to users looking to upgrade existing machines. Their release sparked a lengthy series of lawsuits with Intel while their foundry partner IBM was releasing the same designs under their own branding.
The combination of these events led Cyrix to begin losing money, and the company merged with National Semiconductor on 11 November 1997.[5][6] National released Cyrix's latest designs under the MediaGX name and then an updated version as Geode in 1999. National sold the line to AMD in August 2003 where it was known as Geode. The line was discontinued in 2019.[7]
