Testing Some New F@H GPU2 Cores

post #1 of 44
Thread Starter 
Well I found some new cores for both ATI and NVIDIA GPU2 clients and I decided to test them. These are very rough tests and I might be able to do a few more, but this will definatly not be extensive. I do hope this will at the very least give you and idea of what may be coming, good.... or bad.

FIRST OFF - ATI


Since I tried the new core before taking a screen shot you will see it in the first image. I then went back and renamed the new core and let F@H download the old core again to test if what I was seeing was true or not. Seems it was.

With the new core



With the old core




NEXT UP - NVIDIA

Again I tried the new core first and then went back and renamed it and let F@H download the old core again to test my suspicians. The images kinda speak for themselves.

With the new core



With the old core




As you can see there looks to be at least some difference coming down the pipeline for both clients.

If you want to test these new cores I can explain where and how to get them, just let me know.

ROUND 2

Ok I have tested a different WU for both the ATI and NVIDIA clients to see if any changes. Results below.

ATI

Well it looks like the ATI client is virtually unchanged between the new core and the old (current) core with this WU. I am ok with that I suppose

New Core




Old Core




NVIDIA

Well just as before the images speak for themselves.

New Core




Old Core





As you can see overall between the two different WU's I tested it looks half-way bright for the ATI side, on the other hand all you NVIDIA folders (me included), it looks like we are gonna take a beating unless something changes between now and when this core is released. BLEH!!!

Do you have a link to the old core's???

I started a thread on that last time they update3d them but nothing came of it!

YAY ATI!!!!!!!!

I believe the primary difference for the Nvidia client is that it allows for much larger WU's.. which will lower PPD, as the GPU takes longer to process the WU..and ironically less points are awarded [if you look at time/points comparison with other smaller WU's]...yet your tests show, the same WU's running much slower in the new core.

I think it's in responce to all the peops crying about unstable machines errors so they nixed the optimizations.

I hope to test this on one more WU to see if it is WU specific or not, but at least on this particular WU it is definitely going down.

I just let F@H download the old core. By old cores I mean the current ones everyone is running. I do have some older cores stashed on my machine, but I don't know which version(s) or if they will even work with the current WU's.

My goal was to try and capture the same WU with each core to be able to actually tell any difference and it looks like it sucks

Ugh that sucks, I hope we're not forced to use it anytime soon, I havn't had one single problem with the current core ;l

Never any constants are there? Can't go 6 months without completely changing the system.
