Of course, it had help from parent Intel on that front. From the 845 with DDR support to last week's introduction of the 850E with its 133MHz bus support, Intel has done a good job of making sure that the Pentium 4's NetBurst architecture has been well fed.
Not that Intel is alone in this endeavor. In fact, Intel has more help than it even wants. Rival chipset maker VIA has, in spite of a lawsuit between the two companies over rights to the P4 bus, produced its own chipsets for the Pentium 4. First was the P4X266, with support for DDR SDRAM at a time when Intel's own chipsets supported only RDRAM or PC133 SDRAM. Next came the P4X266A, featuring greater performance thanks to an improved memory controller and ATA/133 support. Now, we look at VIA's third Pentium 4 chipset, and the third time really is the charm. The new chipset supports a 533MHz bus and DDR333 SDRAM, and that's just the tip of the iceberg. Let's take a closer look at VIA's P4X333.
