My last graphics card was a passively cooled ATi and was bought 3 years ago so I'm way off the curve and in need of help in regards to these Nvidia cards. Googling brings up plenty of stuff but I've been out of the game so long I have no idea what half the stuff on gfx cards does (last time I paid attention PCI Express ports didn't exist) so hopefully someone can illuminate a few things for me.
Mathematica and Matlab now allow GPUs to be used to do number crunching, which is of significant interest to me. Nvidia have graphics cards aimed at serious high end computing and clustering, the Tesla and Quadro, but the price of the Teslas is eye watering and clearly not something you put in your home PC. Quadros seem to spread from £100 up to the Tesla price range north of £3000 and Geforces aren't as expensive, but still have their moments.
I'm primarily interested in general number crunching, just masses of "Add these, multiply that, invert matrix there, Fourier transform this", rather than rendering, CAD, etc. Wiki says some Quadros are pretty much just Geforces which are software relabelled. Does anyone know what sort of performance difference there is? Also, I've seen Youtube videos of real time solving of the Navier Stokes equations using a GPU, something a CPU can't hope to presently do, so I'm wondering if there's a list anywhere of what sort of operations the GPUs are good at.
Thanks
