New Mac Books and CUDA?

[Uli Plank]

Now that the new MacBooks Pro are out: will PPro CS6 support hardware acceleration on these?

Thanks to Apple they are Nvidia again and have up to 1 GB VRAM.

And more importantly: will CUDA acceleration on the GT 650M be of any real use? Is it fast enough? At least on the desktop side the 600 series seems to a step down from the 500 series when it comes to GPU processing.

Whatever it is it'll be a lot better than the crappy 6750 from the old MacBook pro.

Yes, the ATI didn't any good when I tested it with PPro CS6, hardly any gain over software. I switched it off.

It's not all that much better, GT 650M is still very much a mid-range GPU. In terms of compute, the HD 6770M got you 696 GFlops, the GDDR5 version of GT 650M is rated at 653 GFlops. Looking at some OpenGL benchmarks (on Windows) the GT 650M is roughly 10% faster than HD 6770M. That said, the GT 650M will gain thanks to supporting CUDA much more than being a better graphics card. Also, it is much faster for gaming and pretty much on par with a Radeon HD 7750M. The 7750M is much more efficient though; I think Apple went back to Nvidia because of drivers.

That said, the GTX 680M is probably going to be 3-4 times as fast as any of these mid-range graphics cards and is hands down the best choice for CS6.

So, it looks like MBP plus Thunderbolt boxes…

Does CUDA processing work through Thunderbolt?
