I’m hoping that CUDA throttling is less than the opengl, and a post on another forum for a 460 CUDA being much faster than a 260 CUDA gives me some hope, but ... the 580 CUDA could actually end up slower than the GTX-285, I just don’t know. I’ve search for CUDA benchmarks, but don’t really see any.
The real-world CUDA use in Premiere shown here seems to indicate that CUDA performance hasn’t changed - and certainly hasn’t gotten better.
nVidia can do anything they want, but to advertise the product as if it is faster without telling a customer the real story is in quite poor form. I can’t spend days trying to become a video card ‘expert’. I just want valid info so that I can make a decision based on the facts.
I no longer trust nVidia at all - which is a shame as I’d been very happy with the GTX-285, and always praised vVidia products.
** EDIT *** this benchmark seems to indicate CUDA is getting faster in newer GTX cards!
