I am looking at getting a P4 3.0GHz Prescott for my new system. I just recently saw something listed as P4 3.0E Ghz What is the "E" stand for and is there any differences between the two? The only thing I can see is that the processor is listed for alot less $$$ which makes me wonder...

The prescott is the "E". The prescott was made with 1mb cache whereas the northwood was made with 512k cache. And as for getting a P4 3.0E everyone here at sg says the prescott isn't as good as the northwood version (P4 3.0C). I don't know why, but the northwood benches better than the prescott.

benchmarks are deceiving, a superior processor may suffer from a weak video card in overall marks. Heard they run hot,,, but the same was said about a 1.4 ghz T-Bird. My Dad's t-bird from 2 years ago still flys. Advice on a processor is like getting advice from your buddies on girlfriend choice. In the long run, you are the one who has to handle the ups & downs. So get the one that feels best for you...

The Prescott's have longer pipelines than the Northbridges.

Ashame how that pretty 1MB cache goes to waste on a less superior core. The E referes to the core the CPU uses. C means Northwood, A means i dont remember, E means Prescott. Stick with Northwood("C") for right now.

The "E" series Pentiums out there are not the "true" Prescott chips; they are still Socket 478 but with the Prescott core. The "real" Prescott has an entirely new socket and design and has not yet been released...so if you must buy it's better to stick with the 3.0 "C" for the time being.

I was not aware that Intel chose to hold the name until the release of the socket...
From what I read, they have been having issue in the development of the new pin package.

Well, there is a 2.4A which is a Prescott. But you have to make sure its not the old northwood core so just look to see if its has 1mb and sse3.
HardOcp got one to over clock to 3.2ghz on stock cooling I belive...

533 FSB

The reason why ppl aren't buying Prescott is because the power consumption. It gets really hot and so do the MOSFETS on your motherboard. The overclocking is limited.

Willamette:
Socket 423, 256kb cache, 400mhz fsb, P4As

Northwood:
Socket 478, 512kb cache, 400/533/800mhz fsb, P4As, P4Bs, P4Cs, P4EEs

Prescott:
Socket 478, 1mb cache, 533/800mhz fsb, P4As, P4Es


The A, B, C, E, EE Is not the core. C does not mean northwood, its used to sepparate the 800mhz fsb northwoods from the 400 and 533mhz northwoods.

Ok, now I am more confused then ever

Let me try this approarch... I am building my new PC from the ground up (my dual 800mhz is a tad bit under powered for some of the things I do)

So far I have:
My motherboard is a Asus P4C800-E Deluxe.
My case is a Lian Li PC-7HW Black With Window and Blue LED.
(2) Thermaltake Case Fan Blu LED 3 Function 80mm

I was looking at these processors:

Pentium 4 2.8GHz 800MHz
Pentium 4 3.0GHz 800MHz
Pentium 4 3.0GHz Prescott
Pentium 4 3.2GHz 800MHz

I was opting for the Prescott for pricing and performance. I have never over clocked before but I can see myself getting bit by the bug as speed=more, more=bigger & bigger=better Seeing I really do not want to do this again in 2 months which one should I get and why?

Man if that is the case you maybe should be looking into a dual processor system, eith dual AMD's or Xeon.
I have a 1.9A PIV, and 2.53B PIV and a 2.4C PIV and I can really load them up without noticing them faultering.

Pentium 4 3.2GHz 800MHz for sheer grunt and speed out of those choices

I would say either the P4 2.8C or the P4 3.0C. Prescott isn't really perfected yet because like Tawcan said it overheats and doesn't OC as well. That's why most people say to stick with the Northwood version. The P4 3.2C is kinda expensive, but if you have the money I guess you can go for it. I'd say the P4 2.8C and P4 3.0C have more bang for the buck. Talk to some of the people around here, they can OC a P4 2.8C really well. Cypher has OC'ed his P4 2.8C to about 3.5 I think and knightmare to about 3.4. You can do amazing things with it.
