Northwood, Dothan, Prescott?

post #1 of 8
Thread Starter 
Wow, this is a great site! I wish I found it years ago! Anyway, Got two questions regarding 3 chips; I have a P4 2.4 Northwood which I have been playing around with; recently I got a new Mobo which will allow for the 3.4 Prescott chip (Mobo is Asus P4P800 MicroATX for a small case). I'm wondering if I should get the Prescott considering all the good stuff I'm hearing about the Northwood I have. Is this worth the $200 or so bucks to do? The New Mobo has 2 GB 333MHz RAM, and seems to have ample cooling, and of course I want to overclock it as much as possible! On top of that; I have a Dothan 1.8 which I'm considering upgrading to the 2.1 ($400 bucks vs. $200) Now the thing here is, would the Dothan be a better chip then either the Northwood or Prescott? I know it sounds bizarre, however I've been hearing really good things about the Dothan vs. all others. So I guess My choices are:
1). Upgrade Laptop to 2.1 Dothan / Swap out 1.8 Chip to new Mobo giving me: a Laptop with 2.1 Dothan, a Desktop with 1.8 Dothan Overclocked, and a P4 Northwood Overclocked, (along with a Dual Xeon 2.6 Dell, and a P4 2.0 Dell). This would skip the Prescott purchase.
OR: If the Dothan will fit, pop it in the Mobo and by pass the Northwood (store it or sell it) and skip the Prescott Purchase?
and Finally:
the same as above but with the Prescott vs. the Northwood ($400 Dothan, $200 Prescott: worth the performance?)

I'm really looking for the most performance (3D and Video Editing . . . and of course some gaming). Any and all assistance would be really appreciated.

Thanks,

John K

Well the Presscott probably has the best performance of the bunch but it'll also use a ton of power and produce A LOT of heat. The 2.4 Northwood is known to be a great overclocker with people easily hitting 3 Ghz. + speeds. The Dothan has the most efficient architecture and will be the best at gaming but will top out at around 2.5 to 2.6 Ghz. Personally I'd take the Northwood and clock it as far as I could get it. It'll work well with gaming and video editing especially if you hit 3 Ghz. or greater. just remember to run your ram on a divider as you increase your FSB considering that it's 333 Mhz. ram.

Performance: (1-3)
Prescott 3.4 - 1
Northwood 2.4 - 3
Dothan 2.1 - 2

Efficiency: (1-3)
Prescott 3.4 - 3
Northwood 2.4 - 2
Dothan 2.1 - 1

Coolest Operating Temperature: (1-3)
Prescott 3.4 - 3
Northwood 2.4 - 2
Dothan 2.1 - 1

Fastest FSB: (1-3)
Prescott 3.4 - 1
Northwood 2.4 - 1/2
Dothan 2.1 - 2/3

Fastest Cache: (1-3)
Prescott 3.4 - 1
Northwood 2.4 - 2
Dothan 2.1 - 3

1 being the best, 3 being the worst (these are overall, not just in certain cases).

Overall: I would think the Prescott would be the best overall, due to its extra 512KB L2 cache over the Northwood (the Dothan rules in that departement though). It has SSE3 extensions unlike the other two also. As it has the highest operating frequency its wins even though the Dothan's efficency brings it very close to the Prescott, but because it has a weaker FSB speed and slower cache it can not catch up. In some games however it will beat the 3.4 because they will only be after heavy processing power.

Dothan.

This processor is the devil man, with a little OC i had 28,XXX in the SuperPI.
with a Prescott 3.2 640. @ 4.0 i had 35,xxx...

isn't perfect?

Dothan PLEASE.

Ya sure perfect.... if all you wanna do is run superpi instead of actually using your computer . Like themanual says, the prescott is the winner in most cases. The dothan has a good architecture and gets more done per clock cycle. But that's not always what makes a processor rock, although it really helps alot. Depends on what you're doing. The pressy is the best overall though, superpi and other benchmarks aren't the end all be all.

Now if the dothan could match the prescott in fsb and clock speeds etc., and everything the prescott does better, then the dothan would truly rock. Not saying it isn't good, it's way more efficient than the prescott, but they just had to slow it in other ways, bastards . They'll soon release something that has the good fsb's and clock speeds and all that I'm sure, but they gotta milk it you know. They had to make a bunch of people jump on the slow one, so they can make them all buy another faster one soon lol, more $$$ for them. I'm actually looking forward to some upcoming Intel CPU's, bout time they went back to CPU's that actually work efficiently, like they started with the tualatin PIII, then unfortunately blundered with the P4 in comparison of efficiency.

I disagree, the Dothan is a very good contender. Highly overclockable on basic air cooling setups (between 2.6 and 2.8GHz on average). Extremely quick, trumps all the others in gaming performance, overclocked at least (all three overclocked I mean). But the Northwood or Prescott will do better in Video editing and other media creation/editing. So you'll have to base your decision on what you do more.
FSB isn't that big a deal to the Dothan because it isn't starved for memory bandwidth like the Prescott because it uses a very short pipeline and has a large cache. If you do get the Dothan, though, remember, you have to buy the ASUS CT-479 adapter kit as it's a different socket.

Get the Prescott.....you'll need good cooling though
