what cpu is the best for seti???

[Idoxash]

dudes for the last 2 mths i been thinking of building my self a faster pc ( my current pc is a amd 1.2 athlon ) I just found this seti thing and now that i been running it.....i want to know for my next pc that will replace my current one what cpu would be best at seti ( amd athlon/xp intel p4 ) if i go amd i will buy an athlonxp 1600 if i go with intel prob a 2ghz i know the 2 ghz in its self prob kick the 1600 xp but let say at lower speeds are the p4 much more faster????....thanks..

um, im pretty sure that the xp would "kick" the p4... i'll look for data.. but for eccp-109... the p4 gets demolished at any speed...

The Athlon XP owns pretty much all DC projects, SETI included.

Those CPUs really aren't in the same class. A P4 2.0 GHz is going to be way more expensive than an AthlonXP PR1600+. I wouldn't spend the money on the P4. If you want to spend a lot on a new CPU, go for an AthlonXP 1800+ (the 1900+ is hardly any faster at SETI). Anyway, I would think the AthlonXP 1600+ would be pretty close in performance to a P4 2.0 GHz in the first place.

btw, the xp1600 is the best bang for yer buck.. but if u got enough to buy a p4.. go ahead and get a bigger xp

BTW- You'll be happer with the XP

I'd go for a 1800+ or 1900+ Athlon XP. They would kick the P4 at pretty much anything.

My XP1800+ is cranking out WUs every 3:20 or so. I think the P4's are struggling just to come in under 4 hours per WU. AMD, all the way...Plus, the DDR ram is cheaper.

I don't know what you're talking about MrFluffy.

 

[Idoxash]

crazed then i was hoping that the axp would be kick ass just wanted to know haha besides i have always use amd cpus but my first pc ( cyrix ) thanks thoe....

 

[ElFenix]

damn... cyrix... jeez... i remember those things...

i also remember the nx586. a friend of mine was big on them. and i was big on the k5 (it was a good processor... no really! it was faster than a k6 at the same clock... problem was it couldn't get near the k6 in clock... or the pentium, for that matter)

wonder if he ever bought an nx586? i'd like to have one for my collection

oh, and if you don't want that old system i'd be happy to give it a loving home

Umm, actually P4s are pretty damned good at SETi. A top end P4 and XP will pretty much run neck and neck, come January and Northwood at 2.2Ghz then I think the P4 would 'generally' be the fastest desktop Seti cruncher.

My P4 @ 2 Ghz generally does 8 wus a day if I leave it alone, ie just surfing the net etc (usually doing a Wu in just under 3 hours) . While i'm sure there are XPs that can do this faster- i certainly don't think P4s get 'owned' when it comes to Seti. It isn't a DC project just reliant on FPU power like some others

looking at lambchops benchmakrs you can see that the P4s and Athlons are pretty mixed up in terms of results. Notably most of the Athlons are heavily O/C on the FSB. I believe that Seti benefits significantly from memory bandwidth. At defalut clocks even a medium speed P4 (1.7Ghz ) stacks up pretty well vs mid to high end Athlons

Bringing cost into it is another matter, but then WTH would anyone make a processor purchasing decision just on running a SETI client?

Clock-cycle for clock-cycle, the XP's own the P4's. My XP1700 (about 1500MHz) is averaging around 3:35/WU. I would like to see the 2.0GHz P4 keep up with that.

Even if the cost was the same, I would still go with the AMD XP's.

Clock for clock is irrelevant for comparing these 2 processors. The AMD processors don't need the extra MHz and it is a poor reference point anyway. If you averaging 3:35/WU then that is probably slower than a 2Ghz P4 unless you have the FSB pumped up really high.
