Anandtech recently posted an article about a new Intel CPU that released.

Intel has decreased their die size from .13 micron to .09 micron (90 nanometers). But in order to do that had to make some fundamental changes in order to provide a faster CPU. A very interesting read. One of the key things I learned was that existing P4 stocks based on Northwood will remain faster than the new stuff (Prescott) until the new stuff hits 4GHz.
This may impact us when it comes to server purchases, as OEM's are already in possession of these new units. We shall see where this takes us.
