These are the first real benchmarks of the GeForce GTX 780. I know, this is far from gaming experience, but it should give you a small insight about the computing performance of the card.
The OpenCL Environment tab confirms all the specs we were talking about. What I discovered there is that NVIDIA is preparing a new driver for the GeForce GTX 780 launch — GeForce 320.18 — with a full support for the new product.
I will just leave you with the charts, so that you can draw your own conclusions (don’t be surprised with the Radeon computing performance though).
First the top list, then some comparisons.
