Pentium 4 CPU - P4C 3.2Ghz 800Mhz FSB 512k cache vs P4E 3.2Ghz 800Mhz FSB 1MB Cache

[Almighty1]

I was wondering has anyone here used both the Pentium 4 P4C Northwood 3.2Ghz 800Mhz FSB 512K cache and the P4E Prescott 3.2Ghz 800Mhz FSB 1MB cache? From what I read, the former is faster because it has less instruction pipelines but lacks SSE3 while the later is slower because it has more instruction pipelines but has SSE3.

I have used both and depending on what is being tested aside from clock speed either one could be faster than the other by a tiny bit. Overclocked on the other hand you may see a tad bigger difference in speeds but not enough to talk about really.

Interesting. It seems in reviews atleast this one: http://hexus.net/tech/reviews/cpu/69...xtreme-edition, the P4C is faster than the P4E in benchmarks, which one can overclock higher anyways. What about in real world usage, which one would you use? Were you using the socket 478 version since that might make a difference.

This was what someone else said when I did a search on google:
"I own both prescotts and northwoods.. personally I've done benchmarks between them and the Northwoods clearly outperform the prescotts in gaming.
They're also up to 30c cooler and use a lot less power.

Hyperthreading is integrated better into the prescotts which actually slows them down a lot, whereas the northwood was designed for single threads which gives it a lot more raw power. =)"

A few years ago, I replaced the Prescott CPUs in my PCs with Nothwoods when I realized the large difference in power consumption.

stj, that doesn't really tell much as it's basically what Intel says but not real world performance which is the opposite.

As for power consumption and performance, I know the D0 stepping and SL7E5 for the P4E 3.2Ghz Prescott is 89W and not the 103W. The SL6WG P4C 3.2Ghz D1 stepping is 82W. It's the Prescott SL79M/SL7B8/SL7PN that were 103W.
