Hello everyone, Thanks UnknownPL1337 :) Interesting list. Do you plan to update it regularly and to complete it with missing GPU's? ____________ [CSF] Thomas H.V. Dupont Founder of the team CRUNCHERS SANS FRONTIERES 2.0 www.crunchersansfrontieres | |

Yes i do, there will be over 250 GPUs. Tesla, Quadro more and more. | |

only the Memory interface matters 384/256/192 not the memory clock speed. It should be:"only the memory bandwidth matters, which is interface width (e.g. 384, 256 or 192 bit) times clock speed". Together with a disclaimer that if the app is not limited by memory bandwidth on a certain GPU, memory clock speed increases only increase power draw but not performance. In such cases lower memory clocks can lower the power draw. This is generally not the case at GPU-Grid. The app is not particularly bandwidth hungry, but lower memory clocks don't improve efficiency either, as power and performance drop. Edit: you're talking specifically about Folding@Home. I haven't followed them lately, but I'm sure the GPU architecture also plays a role there. We solved this by including an empirical "flops conversion factor". For example in past times if the theoretical flops from a CC 1.1 GPU (like G94) were x, then a CC 1.3 GPU with the same maximum theoretical flops would crunch as much as if it had 1.4x the raw performance. That's because different architectures generally differ in the efficiency with which they can use their maximum theoretical flops in real programs. AMDs VLIW5 was notorious for providing amazing theoretical flops with limited real world applicability (outside older games). MrS ____________ Scanning for our furry friends since Jan 2002 | |

only the Memory interface matters 384/256/192 not the memory clock speed. Could you quote what you would write instead that what i wrote? example ? "if the app is not limited by memory bandwidth on a certain GPU, memory clock speed increases only increase power draw but not performance. In such cases lower memory clocks can lower the power draw. This is generally not the case at GPU-Grid. The app is not particularly bandwidth hungry, but lower memory clocks don't improve efficiency either, as power and performance drop." I bought a GT630 GK208, i will see how much GFlops i can make with it by Modding it :) Wish me luck hehe ^^ I got the Zotac 1GB Version with GK208. I will run this GPU on my PC because my GTX580 is TOOO HUNGRY :( 250Watt+ for 1750Gflops, about 6Gflops/watt, the GT630 G208 has 27Gflops/watt ;) | |
