The Die Has Been Cast: Pentium 4/2533 vs. Athlon XP 2100+
Comparison: 12 Different Chipsets For P4
This table lists all chipsets for the Socket 478 platform. Along with the ones that are soon to come, there is a total of 12 different Pentium 4 chipsets from Intel, SiS and VIA. With regard to the best performance, the Intel chipsets are positioned quite well, while VIA, which, to be exact, does not have a P4 bus license, is at a bit of a disadvantage with its P4X component. The development at SiS is interesting: the manufacturer has a license and is working on SiS 648, which is the first of its chipsets to use a Rambus memory interface.
