Intel 486
Realizes: Integration for mainstream PC workloads (DOS/Windows 3.1 era desktop computing with spreadsheets, CAD, and client/server applications).
The Intel 80486 fused an on-chip floating-point unit, eight-stage pipelined datapath, and write-back L1 cache into one superscalar CMOS microprocessor, delivering deterministic x86 throughput for desktop applications while reducing bus contention compared to the 386.
