Re: [AMBER] laptop GPU support

Amber supports all GPUs with CUDA 'compute' capability higher than 1.3
(which is the first revision with double precision support in hardware).

A (wikipedia) reference that has a good list of GPUs and their compute
capabilities is here: --
and the 640M and 650M have compute capability 3.0. They are not yet
supported, I don't think, but they will be not too long in the future. The
630M is not on the list, but I think it's in the same family as the other

I'm not sure what performance you should expect, as the number of compute
cores in mobile cards is typically lower than the corresponding desktop
graphics card. I've also not seen any reports about GPU performance in
laptops... (and don't forget that the GPU will also be rendering the
screen, so it won't be fully dedicated to Amber calculations, which may or
may not work in the first place).
