Optimal CPU - GPU comparison table [moderate to larger WUs]

Postby bruce » Thu May 08, 2008 6:14 am

This is a continuation of the previous discussion except that everything changed when larger WUs started to be available. For comparisons, the previous discussion was here.

What clients are you running on your Q6600 besides the GPU2 and what's the PPD?

my Fahmon say 3000PPD but i think it's a bug cause i run two client on one GPU and the first is always at 1500.

I'm running 2 3870's.
I was getting 50sec/frame for p4707. Now that is out to 1min 45sec/frame. The activity meter has dropped from 99% to 40%.
p4711 FahMon is reporting 1961ppd at 3min 45sec/frame. Activity meter reads 99%

My cpu usage has dropped. It was ~50% (quadcore) for 2x 4707.
It is now ~35% for 1x 4707 + 1x 4711.

Change the calculation method to last 3 frames.

Athlon64 X2 6400+ BE 3.2GhZ+Radeon HD 3870 X2 - Project 4711 4 mins 3 seconds/1% - just over 1700PPD - was hitting around 97% of utilization of both my CPU cores, forgot to check GPU utilization :/

C2D E6420 @ Default + Radeon HD3850 256MB and I'm getting 1681PPD (L3F), or 4:20 per percent on p4711.
CPU utilization is 50% all the time, while GPU utilization is 99.99% most of the time. But from time to time GPU utilization drops to 0, as you can see below. Is this kind of behavior considered normal?

Yes of course, dropping to 0 shows the time checkpoints are written to disk, you can configure it by >configure >advanced by selecting 3-30 minutes.

CPU @ 50% shows your dualcore-CPU is only loaded for GPU2-client, you could optional install another CPU-client for FAH, right ?

@Kingcarcas
No other clients for FAH, just one BOINC-client with 3 cores active. For details view my first posting in thread before.

q6600@3.0 GHz - 2600 Pro (600/700) = 99% GPU Activity, 640 PPD (4712 project) (win xp pro sp2, Catalyst 8.3, gpu folding 6.11beta3, 512 mb hypermemory on videocard)

(just to add: 1% on 2600 Pro is 13m17s)

Got my 1st p4713.
FahMon is reporting 2307ppd. 3min 43sec/frame GPU utilisation is 99% CPU utilisation is 90-98% on one core.
I'm having the same problem with it slowing p4707
P4707 is FahMon 814ppd. 1min 44sec/frame GPU utilisation is 39-43% CPU utilisation is 30-40% on one core.

I would like to know why my performance is dropping on p4707 when a large WU is assigned to the 2nd GPU. If both GPU's are assigned p4707 it's 50sec/frame with 99% GPU utilisation and 90-98% CPU utilisation.
I haven't had 2 4711-4713 WU's yet to compare.

Two Wus have EUE'd with my HD2600XT clocked @ (924/700) so I dropped the clocks down for the current WU that is running (Project: 4711 (Run 29, Clone 2, Gen 0) down to (857/700) to see if they still EUE. If they still EUE 857/700 I'll try default clocks (800/700).

Other than that FAHMon calulated the following:
4713 - ~975.91 ppd (HD2600XT @ 924/700)
4711 - ~773.46 ppd (HD2600XT @ 857/700)

I suggest you get an aftermarket cooler. The card wont last long running 90C temps 24/7.
