Best GPU for maximum memory i/o for TDP of 90 watts.
I appreciated you trying to help me Paul, you helped me back in 2004 with a
motherboard However the graphics cards from nvidia are unable to play dx11 games at 1920x1200 which is my monitor resolution so they will be useless on the long run... so it's better to wait for me if I want to game... (wow another monitor flash...) I'm gonna try downloading and installing paralle insight on my computer if that don't work maybe I will change my mind and spent a lousy 50 bucks for gt 520... but I won't like it if I can't play my games which I used to play... but maybe it's for better then I focus more on programming instead of gaming Apperently parallel insight 2.0 needs a gpu and drivers, and it doesn't say if gt 520 is supported. I am quite sick of it... but I will buy the damned graphics card anyway... just this once... to give nvidia's cuda a try... sigh damn you nvidia you better support this card or I won't be happy ! =D Bye, Skybuck.

Anyway I will assume the 90 watts. I am interested in replacing this graphics card with a CUDA enabled graphics card. I want to use it for maximum memory input and output this means maximum ammount of reads and writes to the graphics card's memory, also the more memory the better. Calculations are not that important. There are many different graphics cards designs with different memory chips which might or might not influence the maximum memory i/o. Which NVIDIA graphics cards would be best for maximum memory i/o at TDP around 90 watts ?!? I am interested in a single slot and dual slot card. So you may choose two ?!? Bye, Skybuck. 7900 GTX is 84.2 watts (measured). http://www.xbitlabs.com/articles/gra...x_6.html#sect0 The GTX 580 uses 26.5W when idle, and 264.1W when running a game. Memory bandwidth is on the order of 192GB/sec compared to 51GB/sec for your old card. So a high end card has close to four times the bandwidth. If you move down to a lower end card, then chances are the memory bandwidth will be smaller. http://www.xbitlabs.com/articles/gra...0_5.html#sect0 The GTX 550 Ti uses 10.7W idle and 91.1W in a 3D game. Memory bandwidth is 98GB/sec compared to your old card at 51GB/sec. http://www.xbitlabs.com/articles/gra...c_3.html#sect0 You can get a GTX 580 with 3GB of memory on board. http://www.newegg.com/Product/Produc...82E16814130655 The GTX 550 Ti is available with 2GB of memory. http://www.newegg.com/Product/Produc...82E16814130652 The GTX 580 is a fairly long card, so it would be a good idea to check the clearance available inside your computer case. The GTX 550 Ti is a bit shorter, and likely to fit in more cases. Check the motherboard, to make sure the SATA connectors are not underneath the tail end of the video card. Some motherboards have right-angle SATA connector columns, to avoid interference from the video card. HTH, Paul |

However, there is an even more interesting problem : is there a graphics card which would prevent you from spamming 5 newsgroups with 17 messages (each ; with no followup) about your personal shopping list ? You're complaining to/about Skybuck Flying. It's no use, he won't change his attitude, BTDT -- several times. I think the only sustainable solution to this problem is so radical that it's probably illegal in most civilized countries. Cheers Wolfgang |
