The first computer system to ship with an i486SX on its motherboard from the factory was Advanced Logic Research's Business VEISA 486/20SX in April 1991. [8] Initial reviews of the i486SX chip were generally poor among technology publications and the buying public, who deemed it an example of crippleware .
The introduction of 3D graphics spelled the end of the 486's reign, because of their heavy use of floating point calculations and the need for faster cache and more memory bandwidth. Developers began to target the P5 Pentium processor family almost exclusively with x86 assembly language optimizations which led to the usage of terms such as ...

Intel DX4 Overdrive. IntelDX4 is a clock-tripled i486 microprocessor with 16 KB level 1 cache. [1] Intel named it DX4 (rather than DX3) as a consequence of litigation with Advanced Micro Devices over trademarks. The product was officially named IntelDX4, but OEMs continued using the i486 naming convention.
The Intel i486SL is the power-saving variant of the i486DX microprocessor. [1] The SL was designed for use in mobile computers. It was produced between November 1992 and June 1993. Clock speeds available were 20, 25 and 33 MHz. The i486SL contained all features of the i486DX.
