There are several suffixes and variants including:

• 486SX - 486 with its FPU disabled
• 486DX - 486 with a working FPU
• 486DX-2 - runs at twice the external clock rate
• 486SL - 486DX with power conservation circuitry
• 486SL-NM - 486SX with power conservation circuitry
• 487 - 486DX with slightly different pinout for use in 486SX systems as FPU
• OverDrive - 486DX-2 with slightly different pinout for use in 486SX systems
• RapidCAD - 486DX in a special package with a companion FPU dummy package for use in 386 systems
• 486DLC - mix version by some manufacturers, featuring a 486 instruction set and a 386-compatible pinout

The 486 processor has been licensed or reverse engineered by other companies such as IBM, AMD and Cyrix. Some manufacturers made hybrid 386/486 CPUs (Cxrix Cx486DLC, Texas Instruments TX486DLC), having a 486 instruction set and a 386-compatible pinout. For more Information on x86 processors please refer to the x86 processor FAQ or CPU+Mainboard FAQ (german).

以下是引用playboyzhp在2005-5-29 7:17:05的发言： 好贴子，有帮助！

却实好东西

关于CPU基础知识，我的小站里面有一些资料。但不是很全面，而且很久没更新过了。[
