What is the best graphics card for folding?

Recommended Posts

Found this article at bit-tech. Worth a read if you are folding.

 

The GTX 460 is apparently the most cost effective card for folding at the moment, 768MB version for folding only or the 1GB version if you like to play the odd game or two.

The GTX 480 is the most energy efficient? |V|YTH0S isn't going to like this

its nice to finaly have some form of test to compare. i'd love to see if they keep it updated every few months when new cards come out.

 

i confused as to why they had such a large range of the nvidia gt 2xx series (including both versions of the gtx260) and a geforce 9600 GSO. the argument for the 4 series ("any of the modern cards we've tested in this article will be faster than a HD 4000-series card") could have been applied to the two cards i mentioned above.

i remember my 4870 getting like 3k PPD, it wasn't worth even testing. thats less than a 9600gso and 3 times the wattage. its really a waste to fold on ATi cards sadly.

 

also a heads up it looks like there is a quadro out with no consumer version yet and its only a single 6pin! i bet its going to be the GTX 450

 

NVIDIA Quadro GPU Quadro 4000

CUDA Cores 256

Form Factor 4.376” H x 9.50” L / Single Slot

GPU Memory Specs:

Total Frame Buffer 2 GB GDDR5

Memory Interface 256-bit

Memory Bandwidth (GB/sec) 89.6 GB/s

Feathers un rustled :P, I'd run two 460s for the same money

I don't run my 480 24/7 due to power consumption concerns (even if it is the most efficient), but here are some quick numbers I have for mine. These are with fan speed ~80%. One downside to the 400 series is the core/shader's can't be unlinked so the core clock must be increased along with the shader clock, producing more heat.

 

700mhz = 73C, 0:37 TPF, 14267 PPD (stock)

775mhz = 74C, 0:34 TPF, 15526 PPD

800mhz = 74C, 0:33 TPF, 15997 PPD

825mhz = unstable, need more voltage

can you undervolt at stock clocks??

I've been spending my time trying to see how far I can push my rig for the 3dmark06 contest so hadn't considered that (just the CPU so far, those GPU numbers were a quick 10 minute experiment). A quick trip to Google showed that it's possible to undervolt at stock clocks and see a significant temperature drop.

 

Thanks for the idea!

My GTX 460 is doing 8600PPD at stock, that's as much as my 2 x 9600GSO's. I will probably try overclocking when I've time and probably throw another one in sometime in the future.

 

I know you can't SLI whilst folding but does the bridge need removing, anyone know?

I wants! But got to save the coins.

 

I dont think the GPU3 client requires SLI to be disabled. Even if it does, the bridge doesn't need to be removed. Are you using GPU3? Your PPD looks a little low. My GTX260 does 7000 at stock and the GTX480s do about 16,000 stock.

As far as I've read, my card is performing as expected. Stock = 700 core, 1400 shader, 1850 memory.

 

From this link, I've found the following numbers, with my results in red:

 

Shader / Memory

1945Mhz / 2230Mhz ------- 19,552.00

1802Mhz / 2002Mhz ------- 18,786.22

1789Mhz / 2124Mhz ------- 18,173.8

1700Mhz / 2110Mhz ------- 17,029.20

1700Mhz / 2000Mhz ------- 17029.16

1644Mhz / 2048Mhz ------- 16,470

1650Mhz / 2100Mhz ------- 16,470

1600Mhz / 1850Mhz ------- 15,997

1550Mhz / 1850Mhz ------- 15,526

1550Mhz / 1960Mhz ------- 15,501.2

1504Mhz / 1932Mhz ------- 15,058.29

1400Mhz / 1850Mhz ------- 14,267

 

However, that being said, if there are any tricks to improve GPU PPD I'd love any tips anybody has. I currently use the GPU3 systray version running in windows 7. Does the console version give any increase? I plan to switch to it once I'm folding on both cards -- which will most likely happen after I try undervolting and am comfortable enough with the temperatures to run them 24/7.
