| Intel Pentium4 "Prescott" To Scale or not to Scale, that is our question. | |

Intel Prescott Starting at: |
Comanche4
Comanche4 is one of the prime examples for the Prescott being a mediocre performer but what happens to the scalability?
The lack of performance of the Prescott is actually a very good indicator for what Comanche4 really measures, or rather, what the factors are that influence the performance. We have known that clock speed as well as memory latencies are important but even more important appears to be the internal data access by the CPU, i.e., the pipeline stages.
At first glance it appears that there is a slight advantage for the Prescott with respect to scalability but keep in mind that other system limitations weigh in as well that may cause the non-linearity in scaling for the Northwood.
