Prescott's Little Secret

In learning about Prescott and trying to understand just why Intel did what they
did, we came to realization: not only is Prescott designed to be ramped in
speed, but there was something else hiding under the surface.

When overclocking a processor, we can expect a kind of linear trend in
performance. As Northwood's speed increases, its performance increases. The same
is true for Prescott , but what is important to look at is increase in
performance compared to increase in clock speed.

Prescott 's enhancements actually give it a steeper increase in performance per
increase in clock. Not only can Prescott be clocked higher than Northwood, but
as its clock speed is increased, it will start to outperform similarly clocked
Northwood CPUs.
