oooo interesting....

Biffa · 31 Jan 2011 at 12:52

I know, looks like the 58xx range are the sweet spot.

k3v · 31 Jan 2011 at 13:04

i wonder how it will compare to nvidia cards?

Biffa · 31 Jan 2011 at 13:12

Thats what should be interesting! So now you can run Multibeam and Astropulse on Ati

Just been trying this out on my 5970. It seems to use a full core on the CPU for each WU and only using 80-90% on the GPU cores. Is this normal for SETI?

You are our guineapig so you tell us

Still no use whatsoever for my HD38xx GPU. I hereby go to sulk in the corner. :'(

Phil any news on how the 5970's are getting on with seti?

I think im down another one, was getting random but increasing crashes in milkyway on the card not connected to a monitor,tried it in another box and have screen artifacts :mad:

Do we know what kind of performance ATI can acheive yet?

my 5850 and amd 940 get 12500 with a very large pending list.

I would assume you'd be able to run 4-6 mb on a 6950 and 6970 thats going to at least double output and since its clocked a whole lot higher it will complete the work faster. I would hazard a guess at around 25k or more including the cpu work.

I've been comparing my GPU on other projects and have found that its not quite as fast as a NV 275. However on Seti and running multiple WU's at a time it seems more like a fermi 460 with its ability to run multiple WU's
the one advantage ATI cards have is we can run AP WU's on our GPU's. I finish a non blanked WU in 90 minutes. That is I can finish 2 AP unblanked in 90 minutes because I can run 2 at a time.

I suspect the NV 5XX series and ATI 6XXX series will be quite comparable on seti.

As stated before, the OPENCl for the ati cards is just getting started.

Thank you Mr Biffa

Well then, it looks like I shall be sticking with nvidia for the time being (as and when I can get replacements for the cards I just sold) - as I really don't like the drivers (and interface) for ati.

Just a personal preference - with nothing else to justify my choice.

I didn't run it for very long but it was doing a WU in about 28 minutes. I was only getting an average of 39% load on the second GPU core for some reason :confused:

I wasn't really happy with it using two full CPU cores so I have gone back to MW. At least I didn't get any BSOD while it was running which is a bonus. I'm Getting about half a dozen a day now :mad:
