Does anyone know what the advantage of Intel's new "Prescott" CPU? I expected it to run at lease at same speed as it's Northwood siblings, but faster for certain applications that utilise the new instructions included in the Prescotts. In fact, it's 1 MB cache should make it a faster processor. However, benchmarks have proved the processor to be SLOWER than its Northwood predecessor on most applications, despite the extra money the consumer has to pay for the Prescott. Can someone please advise me on this, so I can choose a CPU for the new computer I'm building? I want to choose something that's fast and future-proof. Should I stear clear of the Prescott? Thanks.
