Just wondering, how long does it take for a certain CPU to finish an awerage WU ?
Could be interesting, for someone building a new comp ?

I´m up first..

Athlon XP 2600+ around 3 hours - 3 hours 15 minutes

Keep crunching

Athlon Xp 2200+ 3:29
P4 1.8 xp 5:22
p4 2.0 xp 5:54
p4 2.0 xp HT 4:22

AMD Opteron 242: ~1,5 hours per wu

AMD64 3200+ (orig. @2200MHz but overclocked @2310MHz) XP SP2 ... 2 hours 20 minutes.
P4 Northwood 2.6GHz HT XP SP1 ... 4 hours 30 minutes (2 WU in the same time)
P3 666MHz W2K SP4 ... 10 hours 30 minutes

ALL GLORY TO THE HYPNOTOAD!

My Stats

P4 2.8 (non-overclocked), HT, 800MHz FSB, allowing "always running" and sharing equally with climateprediction.net. Results range from 4 to 5 hours. Variability possibly depends in part on using the computer for other functions.

P4 2.8 HT standard. 2 units in 3 hrs 40 mins. Avg 1 hr 50 mins each.

P4 2.4 Celeron. 2 hrs 20 mins to 3 hrs 20 mins.

Acer Extensa Intel Pentium M 1.5 GHz (2 - 3.15 hours/WU)

Dell XPS Intel Pentium 4 CPU 3.4 GHz HT (2.15 - 3.25 hours/WU ,but twice HT)

They work together-> every hour a WU result is sent -> 24 WU in 24 hours

(Sometimes I let 1 CPU work for CPDN)

I believe there has already been a thread like this - probably a few pages back.

My most impressive performer is my laptop. Pentium-M running at 1.3 GHz takes right around 3 hours - while consuming a mere 30W of power :) That is about the same time as my AMD 1600+ which is probably sucking 80+ watts. I have seen work units go as fast as 2.5 hours on the laptop but that was a few versions ago and I haven't seen this recently. Under seti@home classic it did a work unit in 2 hours flat. Just goes to show that the P3 core was MUCH more efficient than any P4 core out there.

Pentium 3.2 GHz HT Prescott (not overclocked) - 2 WUs every 3 hours (2 CPUs)

AMD XP2400-M Barton oc'd to 2055-2204Mhz (Mobiles run at variable speed depending on processor load) - avg. WU 2:40

Price of CPU $77.00

Pretty good bang for the buck I'd say.

> Just goes to show that the P3 core was MUCH more efficient than any P4 core out there.

I believe that the impressive performance from the Pentium-M in Seti@Home is due to the fact that it has such a large L2 cache. BOINC Seti@Home makes good use of processor cache. The more, the better!

Pentium M 1.8, 512MB PC2100

AMD 2400+ (oc'd to 2.1, 140*15), 512MB PC133
3:40 / WU

About 8hr 20min on a PowerBook 3,5 (867MHz 15"), but since I do all of my work on this machine, it also has to handle compiling, rendering, etc. (If anyone wants to pass an Xserve my way...)

Where can I obtain an SSE optimized verion of SETI? Also, the slowest Prescott is a 2.8 GHz. Is your 2.66 actually a Northwood?

My laptop, also a Pentium-M 1.3, is also my best cruncher at 2-1/2 - 3 hours per work unit.

While it is based on the PIII core, there are many, many other differences in the Pentium M which make it a low power high performance CPU.
The larger cahce actually has less of an impact on the Pentium M (as it does with AMDs current CPUs) than on the P4 because they have much shorter pipelines than the P4.
