Overview

The Intel Pentium III 700MHz (SL4JZ) is a mobile processor from an era when laptop computing was rapidly evolving. Running at 700MHz with a 100MHz front-side bus and 256KB of L2 cache, it was a capable chip for its time, handling Windows 98, Windows 2000, and early XP workloads. The MPGA 2 socket design was used across a range of late-generation Pentium III laptops from manufacturers like Dell, IBM, Toshiba, and Compaq.

Today, this CPU's value lies almost entirely in its role as a replacement or spare part. For anyone maintaining a legacy laptop — whether for retro computing, running older industrial software, or simply preserving a piece of computing history — a working Pentium III 700MHz in the correct S-Spec can be difficult to find. This makes it a practical pickup for those with a specific need and a collectible item for enthusiasts of vintage Intel hardware.
