Instead of imposing the choose your side statement Movieman, just note the developers (researchers) of the overwhelming power already seen and possibly even break it down by what GPU's were observed. Some scientists may find one brand more to their liking. One example is GPUGrid.net using primarily nVidia for their research. There is a reason they sometimes choose a side. Right now GPU processing has 3 basic sides. CUDA, CAL, or OpenCL. My point is I don't care which they pick, just pick one so that we know which way to go. CUDA=nVidia purchase OpenCL= AMD purchase  |

Personally, if they get to a position for only card supported, I hope they choose AMD. Nvidia has Folding@home, POEM@home, GPUGRID, and various other BOINC projects, where AMD has like 5, and besides this and POEM at home, there aren't any Health related BONIC projects for AMD.

CUDA=nVidia purchase OpenCL= AMD purchase I'd go a step further and say pick OpenCL since it runs on both. It maybe doesn't run as well on nVidia cards, but at least it runs. CUDA will only run on nVidia cards. |

For the numbers listed, it seems like the "AMD Radeon HD 7700 series (Cape Verde)" is a hit. They are relatively cheap ($100-$150 depending on the model) and "fourth-best" in knreed's list.  The 7770 has 1.280 GFlops and the 7750 has 819 GFlops. For those who has to pay the electricity bill their selves: 110 secs AMD Radeon HD 7970 (Tahiti) 250W Thank you for always providing solid data, Crystal Pellet! I have an AMD 7750, but it's in a Linux machine so I can't report anything about HCC GPU WUs. It runs POEM WUs in about 52 minutes, and is a only 50W max card. It is double-precision capable, although that isn't needed for POEM or WCG HCC. I was looking for an energy-efficient, cool-running GPU that could handle any BOINC WUs available for AMD cards, and it is that.  |

Does anyone know why there is a discrepancy in the relative performance? For example the Radeon 7970 should be about 3 times faster than a 7770 and the 5870 should be twice as fast as the 5770. You also have to take into account the high end 7970 can run 4 tasks at a time for an average run time of 30 seconds per task while the 7770 can run no more than a single task. That makes the 7970 more than 4x faster than a 7770.

CUDA=nVidia purchase OpenCL= AMD purchase IMHO OpenCl is the only logical choice because both ATI and Nvidia can run on that platform. Doesn't make sense to exclude one or the other.

I've updated the list at the top of this thread. From the updated list, on 5th. place is the Nvidia-card GeForce 8800 GT. Since GeForce 8800 GT is one of the many cards https://secure.worldcommunitygrid.org/help/viewTopic.do?shortName=GPU#610 not capable of running HCC, it's very strange it's listed at all, and even if it had worked it's unrealistic it's so fast. So, would recommend to filter-out clearly bogus info, since otherwise users gets the false impression their GeForce 8800 GT does work with HCC and will try getting it to work.  "I make so many mistakes. But then just think of all the mistakes I don't make, although I might." |
