Intel 1066MHz FSB chipset slips out

But CPUs not due until later this week

Intel will launch its much-anticipated 1066MHz Pentium 4 frontside bus this week, introducing the new FSB frequency with the i925XE chipset and a 3.46GHz P4 Extreme Edition CPU.

Far Eastern mobo makers were busily preparing product announcements last week in anticipation of Intel's introduction. Indeed, some - like ABIT's Fatal1ty series - have been rumoured to be i925XE-based boards for some time.

The new chipset is an upgraded version of the existing i925X, aka 'Alderwood'. The i925XE, then, supports dual-channel DDR 2 SDRAM, PCI Express, Serial ATA with RAID, Intel's Hi-Definition Audio spec and its Performance Acceleration Technology (PAT). It is not known if the XE adds any further features to the X beyond the higher FSB speed.

Indeed, reports from Japan today add that the chipset has already gone on sale in Tokyo's Akiba zone, hitting store shelves this past weekend. Asus boards have been seen, which reveal the i925XE uses the standard ICH6R South Bridge.

Alongside the i925XE, Intel is set to release a 3.46GHz P4EE, probably fabbed at 130nm with 2MB of L3 cache. Interestingly, this is not on sale in Japan yet. The first 90nm P4EE, with 2MB of L2 cache and 64-bit memory addressing, is expected to ship next quarter at 3.73GHz. Like the current 3.4GHz P4EE, the new part is expected to utilise a LGA775 socket and cost $999. ®
