Message 1026335 - Posted: 19 Aug 2010, 11:33:15 UTC

I have some experience with some cards, and my average RAC with them, considering the period of like one year, are:

9600GT: 4/4.5k
GTS 250: 7/8k
GTX 260-core192: 11/12k
GTX 260-core216: 13/14k
GTX 460: ?? dunno yet, two are cooking atm
GTX 295: 22/25k

All of them are a bit overclocked, air cooled, nothing extreme. The performance, as a rule, is very proportional to the cost of the cards (not cnsidering energy of course, where some of them exceed).

Thanks Firehawk.

So I was thinking, the calc methodology I proposed won't work on the 400 series where people are running multiple units. You'd have to multiply the result of that answer by the number of units....and then it would be close. Less accurate but close.

It locks out edit after an hour....I assumed I could do that to, but it appears I can't.

I might have to host the list somewhere and link to it.

http://www.rjsharkey.com/SETI/GPU.htm

Try that for now. I'm at work and MS word is the only quick html editor...I'll do better from home.

Couldn't you get mods to add this link to the first post, that way it's easier for all? :)

I'm the Mod in the forum of my team, I can only move/hide messages. Not edit.
I guess the Mods here in the forum can do also only the same.

I meant the private/hidden team forum here at SETI@home.
There I'm the founder, admin, mod and member and can't edit messages.

I hope the ATI cards will figure when SETI can run on these GPUs?


Anyone hear anything promising about this? I'd rather look for E.T. with my 5870 than map out where he lives doing MW! :)

Also, anyone know if Knights Corner will be an upgrade possability for crunching WUs? I guess it would need to have an app made for it.

I'm not sure who the mods are, but if any are watching maybe they could do that. Add the link to the first post in the thread.

Cthulhu: I agree, it'd be nice to use Radeons. I'd probably drop Nvidiva completely if I could use ATI on this project...It's the entire reason I have Nvidia cards.

Message 1026810 - Posted: 20 Aug 2010, 20:41:59 UTC

BTW. Like I mentioned already in this thread.
I don't think that the new Cr.-system is finished balanced.

My OCed GTX260-216 make an AR 0.44x WU in ~ 500 secs. In past this WU got ~ 82 Cr.
This would mean a RAC of ~ 14,200 .

Currently I see much values out of range.

So maybe the currently made calculations of RACs could be wrong.

Maybe someone with knowledge about the new Cr.-system could jump in here?

I was hoping we could get some recent results with the modified credit system where possible. Until that happens historical data will have to do...again precision is not likely, but +/- 15% would be great.

As for getting the link moved...is NEW THREAD the only option???? Can I embed a webpage into the forum, not just the link?

Embedding a website is frowned up, if I recall correctly it is to heavy of a load on the server, a link is ok so.

This is what I got for my Gainward GT240, 512MB GDDR5, with
- GPU: 600
- Shaders: 1750
- Memory: 1800
- TDP: 70W

Based on the last 25 results my RAC is 8541 (14931 seconds for 1476 points).

cool, will add to list

I've done another run on the 460, got just under 15,000 this time...tried it with a different set of units, got 12,000 again. Inconsistent so far.

I'm mentioned on the upper mentioned site.. X-D

Maybe, you should mention OC also in the table.
A stock GTX260-216 have - ~ 2,000 RAC (~ 12,000 RAC), I would guess.

What's with the 8,245? If I calculate with the old 82 Cr./500 secs. I get ~ 14,200 RAC.

Also I let run the stock/original MB 6.09 CUDA23 on my system. No optimized app.. ;-)
It's the fastest on my systems. Why? Small look in my profile the mentioned test in the 'quick instruction'.. :-)

@Sutaru, that 8245 for the 260-216 was a result from Tim Norton...It seems fairly low. Perhaps he hit a chunk of VHARs or something.

@VW Bobier, are you getting similar speeds to Frizz with the 240?

Ahh.. O.K. .


Small example what I meant with the new Cr.-system isn't finished balanced:

Same AR WUs: 0.421379
http://setiathome.berkeley.edu/result.php?resultid=1682714441 - 137.38 Cr.
http://setiathome.berkeley.edu/result.php?resultid=1682714470 - 103.31 Cr.

I don't know, maybe currently isn't a well time for to make RAC calculation..?
Or the new Cr.-system could give different Cr./same AR WU?

How is 648MHz(gpus)/1397MHz(Shaders) on the GTX295 sound and yes this is on air with the fan @ 100% with a desk fan aimed at the case. I can complete a cuda WU in about 14-15 minutes and I'm using the 258.96 Nvidia XP x64 drivers.

Oh and the ram is @ 1008MHz and is stock for this EVGA CO-OP card.
