That's about right, yeah. The P4 (excluding the Prescott) has a 50% longer pipeline than the P3, which means that each instruction takes 50% more clock cycles to execute, and so the P4 needs to run at a 50% higher clock speed to equal a P3 (this is a highly simplified explanation but works in practise). The Prescott's pipeline is 50% longer than the original P4's again.

so this would mean that some (mostly socket 423) p4's that are rated at a higher clock speed than the p3's run at the same speed as the p3 1ghz and above??

Also this is a late model p-3 (server edition) with 512 L2 Cache versus a very early model p-4 with 256 cache

yea but still my friend says it can't compete with ANY p4's

does a overclocked pentium 3 [email protected] run at or about the same speed as a pentium 4 2.0ghz?
