The Pentium OverDrive processor upgrades most Intel486 processor-based systems to Pentium processor technology. It is the recommended upgrade option for IntelSX2 TM and IntelDX2 TM CPU-based systems, and the superior upgrade option for Intel486 SX and DX CPU-based systems. It features a true Pentium processor core (superscalar architecture, branch prediction and faster floating point unit), silicon enhancements (separate code and data caches, 16 KB each and 32-bit bus interface), and package innovations (on-package voltage regulation and fan heat sink).
The IntelDX4 TM OverDrive processor is an upgrade for most Intel486 SX and DX CPU-based systems. It features Intel's speed-tripling technology, enhanced 16 KB on-chip cache memory and a math coprocessor. The IntelDX2 OverDrive processor is an entry-level upgrade for most Intel486 SX and DX CPU-based systems. It features Intel's speed-doubling technology, on-chip math coprocessor and 8 KB on-chip cache memory.
