I’m in the process trying to decide what cards to grab for a bunch of new machines to run as a test bed for our new CUDA based engines.
I have a bank of GTX-8800’s (G80) and was looking into maybe getting a number of the newer GTS-8800’s (G92) and wanted to know if anyone has any specifications for comparing the cards in CUDA apps?
I’m also aware that in the next quarter (it’s the 6th of Feb, 2008 when I’m posting this, for posterity) but we need some cards right now - we will upgrade later if they are sufficiently faster.
According to the nVidia wiki page, the on-card bandwidth is 84.6 (G80) to 62.7 (G92) but the shader rate/GFlops is listed as 518 (G80) and 624 (G92) - so I’m thinking that maybe that with the PCI-Express v2.0 might give enough of a boost to make it worthwhile?
Anyone? I’m trying to work out the whole “2x GTS” vs “1x Ultra” and such to determine the best “bang for buck” we can get for the $$$.
