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]

作为Cyrix公司独自研发的最后一款微处理器，Cyrix MⅡ是于1998年3月开始生产的。 除了具有6x86本身的特性外,该微处理器还支持 MMX指令 ，其 核心电压 为2.9V，具有256字节指令;3.5X倍频;核心内集成650万个晶体管,功耗20.6瓦；64KB一级缓存

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.

1992年，Cyrix推出了其第一代CPU， 486SLC和486DLC，旨在与英特尔的486SX和486DX竞争。 它们还与386SX和386DX管脚兼容，这意味着它们可以作为老化的386主板的直接升级，制造商也用它们来销售廉价笔记本电脑。

2024年7月4日 · In 1992, Cyrix unveiled its first CPUs, the 486SLC and 486DLC, which were intended to compete with Intel's 486SX and 486DX. They were also pin-compatible with the 386SX and 386DX, meaning they...

2024年8月27日 · Cyrix并没有和Intel达成任何协议, 而是通过净室逆向工程生产兼容Intel引脚的CPU. Intel起诉Cyrix没有授权即生产x86 CPU, 但是败诉了, Cyrix的486兼容CPU并没有使用任何Intel的专利.

起初，Cyrix专注于为286和386 CPU生产高速x87数学协处理器，这些协处理器在性能上超越了Intel的同类产品，同时价格更为低廉。 这一创新让Cyrix迅速在行业中崭露头角，并激发了公司向CPU市场进军的雄心。

2022年12月13日 · AMD 的 K5 和 K6 CPU 的表现略好于 Cyrix，但在 Quake 方面，它们仍然不如英特尔的产品，后者是一款非常受欢迎的游戏，也是新一代 3D 游戏中的旗舰。 这使得 Cyrix CPU 的性能差距变得越来越大，该公司在许多爱好者眼中几乎失去了信誉。

The Cyrix 6x86 range has the most powerful processor core of any x86 processor of its generation. Unfortunately, like the AMD K5, it also has a very slow floating point math capability and so was a very poor games and 3D performer.

2021年11月21日 · 當時Cyrix並未透露太多其3D硬體引擎的技術細節，唯一比較有看頭的是維持AGP相容性、又聲稱會比未來AGP 4x還快的「虛擬AGP」界面，與擺明靠高時脈支撐效能。
