Prescott information?

[Dough1397]

Hi i have been reading u alot lately on processors and the one thing that ocnfuses me is that they say the prescott completely sucks becuase of long pipelines and everyone says they suck, but isnt this good for multitasking and more like office type use? I know AMD 64 is recommened for games and what not but what.

Ok so if i was buyign a new computer what would you gusy recommend a northwood or a prescott

and just for some clarification a prescott is anything with 1mb cahce right? (i would be looking at lga775 and 90nm)
and the northwood are the ones with the C marking eg 3.0C? right? always s478 and 130nm?


thanks for your help

please dont keep tellign me amd is better... i just wanna be informed on the topic at hand

thanks

PS: my first post here after reaidng for a week or so .... so hi to everyone

A "C" is a Northwood and "E" is a Prescott. And all Prescotts have a 1MB cache because they are slower clock for clock this makes up for the difference. But be aware the Prescott runs hotter than a Northwood so if heat is a big issue in your case be careful

And welcome to the forums.

prescott CPUs belong to 90nm manufacturing technology... i work in a manufacturing/engineering firm, prescotts have its sets of pros and cons(read the reviews or google it)... the main reason i believe intel shifted to this technology is marketing(i.e. manufacturing cost...)...90nm manufacturing technology enables manufacturers to put more transistors to be integrated in a much more smaller die size and in the manufacturing side, more chips can be made out of a single wafer...that generally explains why prescotts are a bit more cheaper than northwood and also a bit more hotter than northwood...

just wait till lakewood or glenwood and the 925xe mobo maybe even a mobo that will be sli compatible but if u gotta buy now buy a 925 mobo and a p4 3.4 lga 775 its 280 bucks at new egg just get a thermaltake jungle 512 fan to cool it

"E" are prescott and come in s478 and lga775 all have 1mb cache but some are 130nm and some are 90nm? or are all "E" 90nm (even the s478?)

thanks for your help spunducky(nice name ) i am not planning on buying soon but i was recommending to a cousin who was interested in buying a new computer

more transisitors working per sq inch say = more heat right? so i guess that makes sense
the benchmarks dont show real life situations, so i would like to know if the prescott outperforms the northwood in multitasking i think it does as i did read in a few places that the deeper pipeline helps multitasking (preferably someone who has owned both?)

Thanks again for all your help!

Prescott processors are still Pentium 4 parts. You will get similar performance at the same clock speeds between a Northwood core and a Prescott core. The only way that you'll notice a difference between the two is with benchmarks, and even then the differences are mostly insignificant. Since the two perform so similarly, you can let price be your judge.

I think a lot of the bad vibes about Prescott have to do with the fact that it didn't meet our original expectations. The Prescott was going to be the core that took us past the 4.0GHz mark. Power consumption and thermal issues have kept the Prescott family from operating at the clock speeds that it was really designed for, though.

that's the logic behind it but not exactly in inches, way much smaller than that... just imagine, 100 people with 37 degrees body temps fitted in a very small room, surely the temp inside the room will rise up way above than if 100 people be fitted in a much bigger room

and about multitasking in the real world apps, IMO its kinda really hard to tell which is which between northwood and prescott(considering all parameters to be the same i.e. processor speed/HT enabled)...

All the prescotts are 90nm, even s478 Prescotts. Also, another advantage of Prescott over Northwood is SSE3. SSE3 supported software, for example Doom3, performs better for Prescott.

About multitasking, yes, Prescott is supposed to do better. But many people cannot realize the mutitask performance difference even between non-HT and HT, which I think huge, btw.. And for sure, the difference between Northwood and Prescott is way smaller than those between non-T and HT. So, I guess it's ok to assume both would do just the same about the matter.
