Intel Motehrboards Comparisons

A comparison of the features and capabilities of the different Pentium, Pentium II, Pentium III, Celeron, Pentium Pro and 486 Motherboards sold by Intel Corporation.

Please note that Magenta Systems does not sell motherboards or any PC hardware, nor can we recommend any dealers that do so. These pages are purely for comparative purposes.

This page is no longer updated and does not include any motherboards released since 1999.

The Intel Motherboard Reference is compiled by Magenta Systems Ltd from Intel motherboard data sheets.

Covers all current Pentium III, Pentium II, Celeron, Pentium Pro, Pentium and 486 motherboards, detailing code name, BIOS level, chipset, slots, memory and I/O capabilities. Includes

The Archive Version contains original Excel version 5 or 7 spreadsheets formatted to print on single sheets of paper. Archive also contains converted text CVS, QuattroPro WB2 and Lotus 123 WK4 versions (less well formatted).

Version 15 adds several new Pentium II and Pentium Pro motherboards, mainly aimed at servers.

Version 16 adds the new BX and EX chipsets and new motherboards using these chipsets.

Version 17 adds the new NX and ZX chipsets, new motherboards using these chipsets, and other new PII MBs.

Version 18 updates existing motherboards that are Pentium III capable, and adds several new MBs using GX2, BX and ZX chipsets.
