80486DX
The Intel 80486DX, often shortened to 486DX, is a 32-bit microprocessor released by Intel in 1989. It was a significant advancement over its predecessor, the 80386, primarily due to the integration of a floating-point unit (FPU) and an 8KB cache directly onto the processor die. This integration eliminated the need for a separate math coprocessor, improving performance for applications that utilized floating-point calculations. The 80486DX was initially available at clock speeds of 25 MHz and 33 MHz, offering a substantial performance boost for personal computers.
The processor's architecture included an on-chip instruction cache and data cache, which significantly reduced the time
The 80486DX became the backbone of many high-performance personal computers in the early to mid-1990s. It was
