Intel rushes to implement NX bit in September

Desktop Roadmaps But not all chips will support it

CHIP GIANT Intel is rushing to implement execute disable bit on Pentium 4s and some Celeron Ds as early as September.

But it will only be implemented on Pentium 4 560s, 550s, 540s, 530s and 520s at first, and only on LGA 775 versions of the Celeron D at 340, 335, 330 and 325.

As revealed here some months back, Intel will introduce a 1066MHz system bus based Pentium 4 Extreme Edition at 3.46GHz, with 2MB cache and using LGA775 in mid-October. Later, in Q4, it will introduce a 3.74GHz EE chip with execute disable implemented.

And it will launch the Celeron D 340 in both LGA775 and 478 pin versions in later September.

Bus-warsIntel appears confident that its Smithfield dual core chip will become available in mid-2005, this is for "creativity PCs" and "lifestyle PCs" as well as for the corporate marketplace, and will use the Glenwood and Lakeport chipsets. There are likely to be three SKUs (stock keeping units) using LGA 775 built on 90 nano technology.

The Lakewood and Glenwood chipsets are both scheduled for the second quarter of next year.

We thought that the Intel 915GV and 910GL chipsets, which support PCI Express, had already been launched by Chipzilla, but according to the week 31 roadmap we saw at the Porcupine yesterday, the 915GV Express will come on the 30th of August, while the 910GL Express will arrive in September.

Intel is still set to make price cuts on the 22nd of August. We've published those details earlier and they're unchanged, and so are Celeron D price cuts slated for that date. µ
