Message boards : Graphics cards (GPUs) : CUDA 4.0

Just when we thought we might get around to moving to 3.2 the green team announces 4.0! Well.. actually a pre-release version will come soon (4th Mar) and there's been substantial progress. This should definitely make developing easier. Not so sure about backwards compatibility, though. | |

Hello: In Lynux (Ubuntu 10.10) for months that work with CUDA 4.0 without problems. Greetings. | |

Not so sure about backwards compatibility, though. Given their track record, I'm fairly sure what it will be like - here's hoping it supports 400series Fermi's ;p | |

400 series should be fine. There is no chip change as yet. | |

Not good news for CC1.2 cards; they dont fair well with 3.1. | |

Because fermi cards without the latest driver would not work. | |

Fair enough, there are lots of people that don't have the latest driver - perhaps around half would get caught out, and that's a lot of lost potential. | |

is this gonna run closer to 100% gpu utilization folding@home is depressing. | |

At present I am seeing around 70% GPU utilization for the long tasks, but perhaps this will change with tuning. | |

400 series should be fine. There is no chip change as yet. Does this mean it's no longer useful to buy a GT240 instead of a GT440 or GT440-OEM? | |

Given that the 6.12app is to be pulled and the poor performance of the GT240 running the 6.13app, at this stage I would say there would be little point getting a GT240. For those that have one, they will be good right up until we have to use the 6.13app. Cuda 4.0 is still in Beta so it might be a while yet. | |

That appears to leave me with no suitable choices of which graphics board to get when I'm under a power limit of 350 watts total for each computer. | |

I agree. It’s unfortunate that no-one has posted the results of a GT440. As is I would not recommend getting one. So unless your systems could take GTS450 or GTX550 Ti cards (106 and 110 TDP) then I guess you should play the waiting game; these planned changes along with the CC2.1 design issues mean it’s not a good time to buy an entry level crunching GPU for GPUGrid. | |
