GPU's ATI vs NVIDIA

[Luc Gauthier]

Hi, For the past 5 days , i spend time to try to find out witch one is the best ..
Ati or NVIDIA for running GPU's?
Few questions here:
1=What is the maximum GPU's Boinc could recognize?
2=There is Some NVIDIA card that have around 400 Cuda's, what does it means?
3= And How many Cuda's for running a GPU?
4=Here the situation: I have an ATI Radeon Hd 3200 and Boinc use .05 of my cpu & 1 GPU (i use AMD phenom 4 cores) so my RAC is around 650 wu's.:mad:
But here is my problem there is a data cruncher having same cpu and os, and he use NVIDIA geforce Tx480 and is actual rac = 48,500 wu's:thumbs: , so i am far away to understand it ?
5= How many Wu's i can crunch at the same times using whatever GPU for maximize my RAC.
Thank' for your Help i hope a genious could answer!!!:blush:

Which project are you running this on?
Some of the projects are heavily optimized for particular classes of GPU's. You may be better off moving to a different project. I don't know that particular card but I think it's on the lower end of the GPU's whereas the Nvidia 480 is a very high end CUDA card.

BOINC will recognize most any high end cards, but I think the question is more which of the lower ones it recognizes.

Nice to meet you BOK & Thank's for your quick reply !!! Understood what you said about Compatible Project and Cuda..
So if i use GeForce GTS 450 , per exemple...(192 Cuda cores) and using projects list for NVIDIA, how many wu's (beside my 4 cpu) will run at the same times?

[Bok]

The wu's are usually configured to use all available cores in parallel so it is only 1 wu at a time still on the GPU itself.

[Luc Gauthier]

Ok , so if i use like you mention ''Nvidia GeForce GTX480 ''(480Cuda's Cores)can you estimate roundly how many wu's per day could be done?.
An average will help me alot to decide if i add another pc or go for that card instead???
Thank's again

I and Bigred work milkyway with GPU's
I have 10 Vid cards and Bigred has 15 -+
I have all ATI's and Bigred has a mix you can look at our output here

One ATI radon 5850 will do the work of 15 Quad cores @ 2.5 Ghz

Here you can get one for 219.00 http://www.microcenter.com/single_product_results.phtml?product_id=0320761
Good luck and :welcome:

Hey , Thank's LAURENU2!!! Wow!!! you are at the top!!!, finally i begin to understand...and i will order that type of card. Imagine the saving, instead of buying 15 pC with 4 core, HDD, Pwsupl,,,,,, i will only add cards on my 3 Actual Pc. Wow , Thank's again Laurenu2, Your the best!!!

As was said before, what Project(s) do you want to run? It really makes a big difference.

If you want to run Milkyway (good credit) you will need a double percision card. ATIs produce the most credit but it must be a HD38xx, 48xx or 58xx card. These will work on most of the other GPU projects. A HD 5850 will zoom through a WU in less that 2 minutes. One of my Nvidia GTX260s (216 cores) takes about ten minutes.

If you want to run GPUGrid you will need a Nvidia card. It doesn't suppoer ATI.

[Luc Gauthier]

Thank'S Bigred...
I will run Milkyway on ATI HD 5850
and GPUGrid on a Nvidia card , any suggestion on a great Nvidia Card?

Sharring this , it's Great, that is why you are the Best...
Crunching Project is maybe the key to the futur!!

:smoking: Do you need a Team to join ?
A space just opened up here at Free-DC
:Pokes: If you act fast it could be yours for a song & dance :banana:

[Luc Gauthier]

Yes , Of course
BTW , i speak and write french
Tell me more and how ....to join the ''TEAM ''

Luc it is easy - you just need to go to the various projects you participate in, making sure your logged in. Click on "Teams" search for "Free-DC" that will bring our team up click on the team link and then "join team" as simple as that :)..
You'll then join the team and your stats will show up somewhere in here > http://stats.free-dc.org/stats.php?page=index you can drill down to each project you do and find Team Free-DC to see how your doing or since you are a forum member, you can use the stats tool we've made to add all your project Id's if you know them then you can see them all on a single page like this
http://stats.free-dc.org/stats.php?page=usermain&name=gopher_yarrowzoo < that's mine, there is also a CPID (BOINC) only page which uses your CPID - if you know that any boinc project should show up on that page..
I hope that helps..

Bigred what about the 6800 cards :Pokes:
Like the 6870PE51G Radeon HD 6870 1024MB GDDR5 PCIe 2.1 x16 Video Card

Bigred :blush: is our GPU expert her at Free-DC He got me started with GPU-ing :thumbs:

68xx cards are single percision and will not work for MW. The soon to be released 69xx cards will work though.
