The Rise and Fall of Cyrix: The $550M Texas Chipmaker That Beat Intel, Then Erased Itself

Within a year they had built a math coprocessor that outran Intel's. Within four years they were selling a chip that let you upgrade your old 386 for two hundred dollars instead of buying a new two thousand dollar computer. Within eight years they had a processor that beat the Intel Pentium in the software most people actually used, for half the price. They also won their patent war against Intel in federal court, invented the integrated all in one processor that put the first sub 1,000 dollar Compaq in American living rooms, and laid the groundwork for the system on a chip design that runs every smartphone on earth today. And then Cyrix sold itself to National Semiconductor for roughly 550 million dollars in November 1997, watched that value collapse to about 167 million dollars in under two years, got split in half, sold to VIA Technologies in Taiwan, renamed once, and quietly deleted from the market. This is the full story of how a company can win every fight it picks and still lose everything: the FasMath coprocessor, the drop in 486 upgrade, the foundry rights loophole, the 6x86, the P rating disaster, the floating point gap, the coma bug, IBM selling Cyrix chips against Cyrix, the MediaGX that predicted the future, the National Semiconductor merger, Intel's Celeron counterattack, and the marketing decision that erased an American engineering name from history. If you owned one of these machines, if you ever pulled a chip out of a socket with a plastic tool on a kitchen table, this one is for you. SOURCES Cyrix Corporation v.
