Grantsdale chipset series: in the spotlight on March 29
According to French x86 Secret, referring to its own sources, the Grantsdale chipset series (i865 replacement) for Pentium 4 processors is to be introduced on March 29 alongside the Alderwood, the replacement for i875.
Summing up everything we have posted before, I´d like to remind that Grantsdale will be introduced in both discrete and integrated chipsets with P and G suffixes, respectively. The latter is likely to support DDR2-400/533 and DDR333/400, while the formar only DDR2. Anyway, both will support PCI Express. The P model will be designed for 533 and 800 MHz FSB processors as well as the 775-pin Prescott-based P4. G series (including GV and GL) will have Intel Extreme Graphics, while GL will be also designed for Celeron with 533MHz FSB only.
Grantsdale-GV will lack the external graphics support despite the PCI Express x16 slot (unlike AGP, PCI Express x16 is not a dedicated graphics interface). Grantsdale-GL won´t support Hyper-Threading and PCI Express x16, but PCI Express x1. By the way, the new Northway Gigabit Ethernet (GbE) chip will work with PCI Express x1. According to the provisional information, the entire Grantsdale series will support up to 4GB RAM.
Pity, but we can´t provide any new details about Alderwood (designed for 775-pin Prescott-based Pentium 4 processors), but still we suppose it will mainly differ from i875 by DDR 2 and PCI Express support. According to observers from The
Register, PC Watch, chances are good that these chipsets will work with ICH6 Southbridge (with Matrix RAID):
- 4 x PCI Express x1 ports
- Int. Azalia audio (24bit/192kHz)
- 1 x PATA100 channel
- 4 x SATA150 ports
- 8 x USB2.0 ports
- 6 x PCI slots
