Tom´s Hardware Guide have thrown up their sneak preview of Intel's upcoming Alderwood - Grantsdale Chipsets! Here's a snip.

In order to properly run the platforms, which have been overhauled from the ground up. Among the extensive changes are the introduction of DDR2 memory with high performance potential, serial PCI Express as a replacement for AGP (and in the mid-term also for PCI), the radical structural adaptation of systems and motherboards to BTX and, last but not least, the processor socket LGA775.

XtremeSystems.org have just posted up the first US exclusive Intel P4 Prescott Pre-view by their member, FUGGER.

"My processor is a early o­ne with stepping of 1, and the current stepping is 3. my results are from a early sample. Please keep that in mind. Like all products they take time to mature and work bugs out. And I have found out that the chip layout has changed since my stepping was introduced and the current stepping resolves some of the issues I have experienced with this ES chip. Intel has done a great job in responding to the problem and adjusting quickly. I expect clock speeds to be ramped up quickly."

ExtremeTech.com have posted their preview of Microsoft's Windows Longhorn PDC build 4051!

The Longhorn preview also shipped with a 64-bit version that supports AMD's line of 64-bit processors. We were able to install it on our Athlon64 FX-51 system, though we didn't have much time to characterize performance. Any attempt to measure performance on such an early release is pretty meaningless anyway. At any rate, it looks and behaves just like the 32-bit version.
