Prettyscott Vs. Northywood

Which one is faster clock for clock?

if Prettyscott is faster, how much faster Northywood will match up to it?



also, i heard that the Prettyscott is harder to oc... the northy is easier... in general. Is this correct?


what's the default multiplier for say... P4 3.2ghz? 200fsb x quad pumped for the 800fsb chip aight?



PLEASE ANSWER ALL QUESTIONS IF POSSIBLE thanx... :p

:eek:
 
I believe they both overclock well, it all depends what speed you get and it will still vary from cpu to cpu

Northwood is just a bit faster at most things, especially at lower clocks, but prescott is faster in games and has more instructions(though not currently used)

Multipliers would be the speed divided by the bus, so it would be 3200/200, which would mean a P4 3.2(both cores) would have a multiplier of 16.
 
Northwood is still the way to go, unless you have a 9xx chipset. Northwoods overclock great, and run cooler than the preschott.

thanx..

if i could oc the prescott just as good as the northywood then i wanna get me a prescott..

i wanna stick with the lovely 875p :D i heard lots of good things about it..

is Prettyscott hard to oc? i heard that before and it bothers me... in making decision :(

Its not hard to oc, but it runs hot at stable temps. OCed its hot as hell, and can heat the rest of your system up if you dont have great cooling. The extra cache is a plus, but the northwoods still pull ahead in most situations.

ok thanx.. im gonna get me a northywood. :D
 
What's the usual top clock with a P4 northy 3.2ghz with good air cooled?

i got a phase change waits to be utilized.... :D
 
uh

Check out my Sig, prescotts are easy to overclock

with stock cooling my 2.8 did 3244mhz obviously with better cooling it will go higher


stop dissing the prescott, they may run hot but Farcry and Doom 3 love em

nah.. im not dissing prescotts... as a matter of fact i was hoping that chip to clock well so i can get one... but i heard that it's still harder to clock than the northywood.. due to heat like people say..

but by looking at your sig yours isnt' clocked that well... 2.8 to 3.24 is well below my expectation... that looks like it will clock much less than the northwood.....
 
im hoping to get mid 4.5ghz.... looks like prescott ain't gonna do that with the phase change....
 
I didnt know you had phase change :D Either one would be great in your case, the Prescott may pull ahead at higher speeds. (God I need phase change cooling bad, anyone wanna donate?)
 
hey will the P4 perfom the best at ratio 1:1? or clock it higher and run the memory 25% higher clock? would that be better?

What kind of ram are you using? 1:1 is always the best, provided you have good ram.

yea i got one.. :) liquid temp at -30C. Do you guys think that's gonna be beefy enough to push the Prescott at 3.9 or 4.0? I want it stable... for gaming.

yea i got two sticks of CorsairXMS PC3500 winbond bh-5. they run stable at 241fsb with my AMD.. so do you think this will do good with the P4? i donno much about p4 systems... :eek:

:D
 
It may run good when overclocked, but if you have phase change and a P4, you really need PC4000 or above to make use of the full potential of your system. You should be able to reach PC4000 speeds with the BH5 if you in increase the voltage. You may need some active ram cooling though :p. I am running Corsair PC4000Pro (500mhz DDR) at 480mhz right now (3.0@3.6 northwood).
 
if i go with the prescott 3.2, I really really hope I could run 16x241 DC... that's gonna give me 3856mhz... i wonder if my phase change will get me to that. I want to use max out of my ram and use 1:1 ratio you recommended.... thanx for all the help.

yea.. you're rite. my ram is gonna struggle coz they can't do more than 250 reliably... and my ram are naked.. no heatspreader.. i need to add some more cooling lol

what motherboard are you running? what vmem voltage does yours go upto?

I use a Abit IC7-G, max DDR voltage is 2.8V.
 
with phase change a prescott would probably be your best bet for the highest oc.
 
It has been proven time and again that Prescott is faster than Northwood at higher mhz. With the cooling you have, I'd say a 3.4 Prescott should make 4.5 easy. Post pics!

cool..

i was thinking of getting me a Asus P4C800..

I saw the benchmark on the Gigabyte 8Ksomething blah blah(i forgot the exact model but it's a 875 platform) and beats all other 875p boards! costs way over 200 bucks but why is it so damn expensive? me don't get it... :confused:

@##$$%%!!...? 4.5... you gotta be kiddin'... aight?

would a 3.2 prescott do upto 4ghz okay you think? if so i consider buying prescott....

Do the prescotts scale better than the northwoods?

I plan on keeping my socket 478 for awhile, and i see it maxes @ 3.4ghz i was wondering if they're coming out with anything higher than 3.4 (478) or should i just grab a 3.4 Prescott and OC and use that till i have to upgrade to 775?

Prescotts scale better than Northwood due to their larger cache, and other architectural tweaks..

The larger cache, while a liability at lower speeds, comes into it's own at higher clocks because the faster the processor is, the more it will have to access memory for data. So, if the processor has a larger cache, it will be better fed with data at high clock speeds compared to a processor with smaller cache..

Just look at the tbred compared to a barton. At higher clockspeeds, the barton rapes the tbred because of it's larger L2 cache..

If you're thinking of going Prescott, go with S775 because they run cooler and are more future proof..
 
good look getting many coolers for a 775 though, Im getting one soon and ive been trying to find a waterblock for it, everywhere i go doesnt have anything or has something listed but its not shipping :(

btw check your pm

my pressys @ 3.4 not 3.2
600mhz OC with quiet air cooling with a pressy is good enough for me :)

no 775 for me anytime soon, i've spent quite a bit on this 478 system and i'll be staying with it for quite awhile. Besides if it maxes out at 3.4ghz i'm sure 3.4ghz and AGP will hold me over for quite some time.
