80486SX-25 Description

Short technical summary and product information.

The Intel 80486SX-25 is a microprocessor released by Intel on April 10, 1989. This processor contains the equivalent of about 1.2 million transistors. At its release, the fastest version ran at 25MHz and achieved up to 20 MIPS.

 

The 80486 SX variant, released on April 22, 1991, served as a more affordable option compared to the 80486 DX. The primary distinction was the absence of an integrated Floating Point Unit (FPU) in the SX model.

 

Later iterations, such as the DX/2 and DX/4 versions, achieved internal clock rates of up to 100 MHz. The 80486SX-25 is a significant component in the history of personal computing, representing a step forward in processing power and integration.
