:?
With the Prescott "so called design improvent" over the Northwood how would it perform against ie. Northwood P4 2.6GHz 512cashe s478 V's Prescott Celeron 2.6GHZ 256cashe s775.

Would the Northwood be only marginally faster than the Prescott Celeron and would this be because of the slightly larger L2 cashe of the Northwood.

Thanks,

What FSB is the Northwood CPU?

Celeron is 533FSB and Northwood can be either 400 or 533FSB.

Northwood Celeron has 128k L2 cache and FSB400 and runs cold

Prescott Celeron (celeron D) has 256k L2 cache and FSB533, and runs a bit hotter.

I got a celeron D 2.4 clocked at 3ghz - beats a P4 2.4b easily, but my case pannel has a fan to pull fresh air straight through the HSF, max temp 58.

The Northwood "C"/800 MHz units will wipe the floor with a Celeron...

For a Northwood "C" 2.6G unit to be roughly equaled in performance, the Celeron would need to be clocked at about 4.0 GHz.....

Thanks for the "link" - good info, ie. the Northwood suffered from Electromigration.

Overclocking early stepping Northwood cores yielded a startling phenomenon. When VCore was increased past 1.7 V, the processor would slowly become more unstable over time, before dying and becoming totally unusable. This is believed to have been caused by the physical phenomenon known as Electromigration, where the internal pathways of the CPU become degraded over time due to excessive electron energy. This was also known as Sudden Northwood Death Syndrome.



I got nervous when I set the bios to 1.675 volts, then seeing CPU-Z showing volts above 1.7 :oops:

Very Good/Interesting to know though.. :wink:

P4 2.6c @ 3.12ghz (MAX) 1.6v Stock HSF
Albatron PX865Pe Pro Mobo

I was reading your PC specs and I noticed that your 6600GT GC died.

What was the Brand and part #, and why do you think it failed - I'am going to buy a 6600GT soon and don't want a "LEMON" :x

Thanks,

Great xbitlabs links.

Yes Cel D's are good processors for their money.

I had a 2.4 Cel D overclocked to 3.6GHZ with stock cooling and rock stable when playing games.

Vcore was set at default and ran at 55' C - with side case cover removed :D and ambient temp at around 28'C.

Still in relation to the second article - "New Cel to have 512 L2 cashe", I think they could improve a little more (not so much of a performance drop from the top of the line intel CPU's) to compete with AMD.

True, and they've yet to release the Celeron with 512K L2 cache. Maybe they will consider a 1Mb L2 cache to really give AMD something to think about. They will have to make that package a LOT more attractive now that you can buy the PD 805 for only $135. Makes it hard to justify buying a single core Celeron, eh?

Albatron 6600GT 128mb AGP - it used to overheat cause of the crappy stock cooling.

Actually the 2.6GHz Northwood can be 400, 533, or 800 bus. Really. I even own a 2.6C.

wasnt there an EE with FSB1066 on 130nm?

and how fars your 2.6C overclock? mine tops out just over 3ghz at 1.6525v, stock cooling.

There are adventages and disadventages for the Prescott Celeron.
The advantages are the SSE3 and on some of them the EMT64, the 90nm production process instead of 130nm, 12mOPS L1 instead of 8mOPS on the Northwood and the greater memory bandwidth that can be achieved trought the nordbridge of the LGA775 mainboards and the DDR2.
The disadventages are the more pipeline stages built in Prescott core compared to those on Northwood which perform in less opreations/clock and the less L2 cache.
I think that system with Celeron D(keep in mind the better chipsets and DDR2 that give additional performances to the system) will perform better in most apps especialy in the multimedia concerned.

3.15GHz at 1.60v, 3.25GHz at 1.675v IF, and only IF I could keep the voltage fluctuation between 1.625v and 1.725v. Otherwise it would reset or hang. And I had the misfortune of owning an Asus P4C800-E Deluxe, with its droop issue developing over the first month of use.
