Intel Pentium SX968 A80502-90 90MHz Socket 5 CPU Processor P1 ICOMP 735

Intel Pentium SX968 A80502-90 90MHz Socket 5 CPU Processor P1 ICOMP 735

The Intel Pentium SX968 (A80502-90) is a first-generation Pentium processor running at 90 MHz on a 60 MHz front-side bus. It uses Intel's Socket 5 form factor and carries an ICOMP index rating of 735, making it one of the faster chips in the original P1 Pentium family. This ceramic PGA package processor is built on Intel's 0.6-micron BiCMOS process, operates at 3.3V, and integrates separate 8 KB L1 instruction and data caches.

Applications

The first-generation Intel Pentium launched in 1993 and represented a major architectural leap over the 486 series, introducing a superscalar design capable of executing two integer instructions per clock cycle along with a dramatically improved floating-point unit. The 90 MHz variant arrived in 1994 and was among the most popular mid-range desktop CPUs of its era, powering Socket 5 motherboards from manufacturers including Intel, ASUS, Gigabyte, and many others. These processors were used in business desktops, scientific workstations, and early multimedia PCs running DOS, Windows 3.1, and Windows 95. Today the SX968 90 MHz Pentium is sought by vintage PC enthusiasts building or restoring period-correct mid-1990s systems, as well as collectors of classic Intel silicon. Socket 5 boards remain relatively available in the vintage computing community, making this a practical choice for a working retro build.
