Intel 2004 CPU/Chipset Roadmap Updateby Anand Lal Shimpi, Kris Kubicki and Wesley Fink on January 21, 2004 1:29 AM EST

It was recently made public that Intel's upcoming chipsets - Grantsdale and Alderwood - would be called i915 and i925X respectively. We talked about those chipsets back at CES but what we didn't talk about were 915G, 915GV and 910GL. We originally thought 925X would launch only for Socket 775, and 915P for both. However, even though the roadmap is slightly vague it appears 915P will effectively replace 865PE; it will have the same performance of 875P with some extra features: PCI Express x1 and x16, Azalia Audio (Intel's AC'97 replacement), DDR2 and of course the new Southbridge which we will talk more about in a little bit.
Even though 915P will support 533MHz DDR2, we will most likely see DDR2 support showing up only on 925X motherboards. Most manufacturers we talked to during CES did not see enough differentiation between 865PE/875P, and this actually hurt sales in the long run. Even with 925X and 915P, we once again expect a PAT-like interface on 925X. Those in the industry say Intel has also made it a much more difficult enable "PAT" on Grantsdale. Other than "PAT", the only other real difference we can see is support for ECC memory on 925X. Most manufacturers we spoke with with planned to use current DDR on 915P boards, reserving DDR2 for 925X.
The new ICH6 southbridge will make its appearance with the 925/915 and makes some interesting promises. First, in any ICH6 denoted with a "/R" suffix, we will see 4 SATA interfaces whereas ICH5 only had two. As kind of a bonus, ICH6/W will provide integrated wireless. ASUS's P4P800S-E turned out to be a surprising success due to its on board wireless capabilities. Maybe Intel has learned a thing or two from its component manufacturers.
915G has all the features of 915P, but with integrated graphics. While we have no details of the graphics capabilities of the new 915G, it is reasonable to expect higher performance but nothing too impressive based on Intel's prior track record.. Intel anticipates this to be the corporate chipset of choice, and will follow up on the 915G with the 915GV and 915GL chipsets in Q3. 915GV and 915GL are basically just stripped down versions of 915G.
The roadmap coverage continues, we hope you enjoyed this one as well...
