Intel Desktop Roadmap Intel will launch Its 'Grantsdale' and 'Alderwood' Pentium 4 chipsets during the fourth week of June, with an official announcement to that effect likely to be made at Computex Taiwan earlier that month, OEM sources have claimed.
At least, that's what they have told Japanese web site PC Watch, which notes that Intel will launch the 775-pin versions of the 90nm Pentium 4 and the Pentium 4 Extreme Edition at the same time, according to roadmaps seen by the site.
The June release will see the arrival of 2.8GHz to 3.6GHz P4s, with model numbers running from 520 to 560, alonside LGA775 socketed versions of the 3.2GHz and 3.4GHz P4EE. Intel will also offer a second 2.8GHz P4 using the new socket, though this one will only support a 533MHz frontside bus rather than the usual 800MHz FSB, and does not support HyperThreading.
The 3.6GHz P4, which will make its debut in June, will only be offered as a 775-pin part and not in a Socket 478 version, the roadmaps suggest. So too will the 3.8GHz P4 that's due in mid-Q3 (August, basically) and the 4.0GHz version expected to ship next October (Q4). Those two chips will be numbered the 570 and 580, respectively.
Those releases will be accompanied by Socket 775 Celeron chips. In June, we'll see the 2.8GHz Celeron 335, followed by the 2.93GHz Celeron 340 in August, the 3.06GHz Celeron 345 in October and the 3.2GHz Celeron 350 in Q1 2005. Unlike the P4, there will be Socket 478 versions of those chips, launched on the same days. Expect to see a Socket 478 2.53GHz Celeron 325 and 2.66GHz Celeron 330 in June, too. The Socket 478 models at higher clock speeds will share the same model numbers as the Socket 775 versions.
The 2.53GHz to 2.8GHz Celerons launched in June will be the first processors of that classification to be fabbed at 90nm.
The June processor launch will be accompanied by the arrival of the 925X chipset (aka Alderwood) and the Grantsdale-class 915P and 915G. All three support only 90nm P4s and, in the case of Grantsdale, 90nm Celerons. The Grantsdale chipsets also support the slower, 533MHz FSB - Alderwood is 800MHz only. It's also 533MHz or 400MHz DDR 2 only, whereas the 915 series supports 400MHz DDR too.
The 915G includes the Intel Graphics Media Accelerator 900, the new name for Intel Extreme, but like the 915P it can also handle an external PCI Express x16 graphics card, as can Alderwood.
August/mid-Q3 is expected to see the arrival of the 915GV and the 910GL. The former is a version of the 915G but with no support for an external PCI Express graphics card. The 910GL likewise offers only its integrated GMA 900 graphics engine and will only operate a 533MHz FSB. It's pitched exclusively at 90nm Celerons.
Alderwood will continue in service through to Q2 2005, when Intel is expected to offer 'Cedarwood' for the 'Tejas' processor, along with the Grantsdale replacement 'Lakeport'. Cedarwood is believed to bump the FSB up to 1066GHz and support Intel's 64-bit extensions to the x86 instruction set. Expect 667MHz DDR 2 support to, the roadmaps indicate. ®
