i486DX
The i486DX, often referred to as the 486DX, was a groundbreaking 32-bit microprocessor released by Intel in April 1989. It was the successor to the i386 and brought significant improvements in performance and functionality. A key feature of the i486DX was the integration of a floating-point unit (FPU) directly onto the same die as the central processing unit (CPU). This eliminated the need for a separate math coprocessor, which had been a common requirement for demanding applications in previous generations, thereby reducing cost and increasing speed for scientific and engineering software.
Another major advancement was the inclusion of an on-chip cache memory. The i486DX featured an 8 KB
