are any of these GPU's really that much faster than a single Intel or AMD core at these math functions?
Most definitely. Check out GPGPU and see how GPUs are being used to make 'supercomputers'. GPUs are very specialized to their function, and that specialization means that they've vastly more efficient at a certain kind of processing. Someone else can give an accurate account of the performance boost, but pages I'm brining up are suggesting that one GPU is roughly 10x faster than a GPU at the same task, when the algorithm is adapted properly.
If you design a custom board to do this kid of 3D, it's always going to be a generation behind the top of the line, and it's going to be more expensive to produce because of the niche popularity. Less power for more money is never a good way to do anything.
Our GPU will be generations behind the other GPUs but still faster than CPUs at graphics. That being said, I'm encouraging some of the others on the list to design a CPU or DSP-based graphics card, at least as an academic exercise. Please note that this discussion of using a CPU core for graphics is a really old one and has been brought up and torn down many times. You should have a look at the archives. -- Timothy Normand Miller http://www.cse.ohio-state.edu/~millerti Open Graphics Project _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
