Details of Prescott CPUs and Grantsdale chipsets

The Japanese folks over at PC Watch again put a lot of time in composing some very nice graphics and tables about Intel his upcoming CPUs and his upcoming chipset the Grantsdale.

Like most of you will know the socket 478 Prescott clock speeds will start at 3.4GHz and will reach a max of 3.6GHz (ow yeah that is a lot). Later in Q2 2004 Intel will introduce his socket 775 Prescotts, which will start at 3.6GHz and will problably reach 4.0Ghz-4.2GHz by the time that Intel launches his Tejas CPUs which are planned for Q4 2004.

The next graph has more information about which types of memory will be used on Intel his current and upcoming chipsets :

As for the Grantsdale solutions expected in Q2 2004 with DDR2-400/533 and DDR333/400 support, the most powerful discrete Grantsdale-P would likely support DDR2 only, while integrated Grantsdale-G will support both DDR2, and DDR. Of course, the market will se the mainstream Prescotts as well — Grantsdale-GV and Grantsdale-GL — without 533MHz FSB support. These are expected closer to Q3 2004. Grantsdale-GV won't support external graphics despite the PCI Express x16 slot (unlike AGP, PCI Express x16 is not dedicated to graphics only). Grantsdale-GL won't support Hyper-Threading and PCI Express x16, just PCI Express x1. By the way, the new Northway Gigabit Ethernet (GbE) chip will work with PCI Express x1. According to provisional information, the whole Grantsdale family will support up to 4Gb of memory.

And here is a table with all the available information of Intel his Grantsdale chipsets :
