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] .

2024年7月4日 · Precursor chipmaker Cyrix made personal computing accessible to millions with its affordable budget PCs, only to be killed by its best product and its inability to run...

The Cyrix 6x86 is a line of sixth-generation, 32-bit x86 microprocessors designed and released by Cyrix in 1995. Cyrix, being a fabless company, had the chips manufactured by IBM and SGS-Thomson. [1] [2] The 6x86 was made as a direct competitor to Intel's Pentium microprocessor line, and was pin compatible.During the 6x86's development, the majority of applications (office software as well as ...

2021年4月28日 · Cyrix was a scrappy, up and coming CPU manufacturer in the 1990s. They never had Intel’s name recognition, but for a few years they made life more difficult for its larger rivals, Intel and AMD. For a while, Cyrix processor chips were a popular choice for value-conscious PC buyers.

2022年9月13日 · 6x86MX进一步将频率提升至300MHz（PR433），同时更名为「Cyrix MII」，以表示竞争对手为Pentium II。但由于推出较晚，Intel的P6（Pentium Pro、Pentium II）和AMD的K6在整数性能上已经追上Cyrix，浮点能力本来就弱，Cyrix MII失去竞争力。

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.

2025年1月6日 · The VIA Cyrix III was a short-lived Socket 370 CPU produced by VIA using technology it acquired from Cyrix and Centaur, two makers of Socket 7 CPUs. VIA first introduced the Cyrix III on January 5, 2001. The VIA Cyrix III used Socket 370 but couldn’t keep pace with even a low-end Intel Socket 370 CPU.

The Cyrix line of Intel-compatible 486DX2 microprocessors were produced in the mid and late 1990s at clock speeds ranging from 50 to 80 megahertz, and contained an internal 8-kilobyte write-back cache designed to increase processor throughput.

A scaled back version of the original 6x86 core that was compatible with the 486DX bus. These chips are 64-bit internally and 32-bit externally. They have 16kb of L1 cache that can be configured as either write-through or write-back by changing CPU registers. Cyrix branded chips were mostly 3.6V and rated at 80, 100, 120 and 133MHz.
