[VC] NVIDIA GeForce GTX 780 OpenCL Performance Unveiled

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.

Nice to see some drivers ready for the action

Is it me or does that look a little on the low side? Maybe drivers not optimized yet?

No. GCN is great on compute.

OpenCL is AMD's territory. Nvidia is focused on CUDA. Is it so damn hard for nvidia to sit down and optimize theur drivers for OpenCL? I guess they just dont care!

Yep, until Nivida gets off their arse and implements OpenCL 1.2 in the drivers, non CUDA performance will suck.

not surprised, nvidia sucks at compute.

Seems farther below Titan than you'd expect.  Titan is 16% more SMX but 40% higher performance.  Wonder if that is bad drivers, or if Nvidia is limiting compute?

CUDA is a proprietary system that is slowly phased out - or should be - in favor of openCL.
Adobe already switched to openCL and the results are promising. I wish all companies did the same.

Unfortunately opencl appears to be - or portrayed to - not as well documented as CUDA. Many devs find it frustrating to switch - either because they don't want to put the time into it before making their money back for investing in CUDA the 1st place, or simply because they don't see the need to as long as CUDA works "good enough".

Ofc nVidia, despite being part of the OpenCL "Kronos" consortium and aiding its development, has every reason not to push away from its proprietary tech for as long as possible. The more supercomputers or everyday apps are invested in CUDA, the better for them - especially when their best chips cannot compete with 2yo GCN chips by AMD.

nVidia said before Kepler and GTX 6 series even launched that Kepler is a "gamers' card".
I remember the fat little guy saying it... LOL..
