Northwood 2.8 vs. Prescott 3.0

post #1 of 9
Thread Starter 
I am thinking of upgrade my skt478 computer, but the only processor available for my motherboard is the 3.0 prescott. Is it true that the prescott have 31 pipeline stages and the northwood only 20? And does that fact have any impact on the performance at all?

The 31 pipeline stages have an impact on performance. I wouldn't advice you to do that purchase, as in most of the cases you'll find yourself with a CPU that is just as fast as the old one. If the 3.0GHz prescott is a 630 and not 530, it has 64 bit capacity, you may find that useful sometime. Maybe you could find 631 cedar mill core (65nm), I heard they are very OCable.

Hello and welcome

Personally i would go for the 2.8Ghz northwood over a 3.0Ghz Prescott.

For example over the last few months i have compared a 3.0GHz Prescott revision "C" (not very good overclockers compared to D and E revisions) which i could only hit 3.4Ghz stable and that was with the load temps in excess of 60*c.

As a comparison i bought a cheep Northwood off ebay for £50, a 2.4C revision M0 which performs much better than the old Prescott.

I am currently running it at 3.6Ghz and its still 10*c cooler than the prescott at stock speed/voltage.

Yeah you are right in saying that the northwoods have a 20 stage pipeline compared to the prescotts 31 stages.

This means clock for clock a northwood is faster than a prescott, But with the additional steps in the cpu the Prescott can scale higher (hence prescotts at 3.8GHz stock where as the northwoods topped out at around 3.2GHz stock i believe)

He has a Socket478 board i believe

Yup, my bad. I remembered Intel decided to release the 6xx series only for sk775
In that case chesejam I'd stick to the 2.8 northwood and OC it until you upgrade to sk775.

Wai twait wait thought. You need to take a look at what he is doing with his computer. If he is doing alot of photoshopping and repetitive tasks a higher stage pipeline would benefit him. THe thing that high stage pipeliens have a problem with are games in particular as the entire pipeline has to be cleared to give precedance to a new operation. I would go with shorter stage pipeline, but it is erroneous to say that shorter stage is always better than longer stage.

Sorry for the generalisation, I should have mad myself clearer

For OC'ing, gaming and SuperPi a Northwood is prefered. (Obviously S775 prescotts are different )

The additional stages increase the temperature of the processor as well.

Thanks all for your help. Im only into gaming with this computer so i'll just stick with my current proc. But how about upgrading to 1 gig 2-3-3-6 ram and a 7800 gs agp from my current 512 mb 3-3-3-8 and 9600xt? Would that increase the performance noticable?

yes it would be a great upgrade
I think u should try to overclock your cpu more , maybe get better cooling .
edit : also make sure the ram is 2 x 512mb to enable dual channel
