I am sofar doing "functional level" testing of offloading with a GTX 1650 which is I think the most affordable thing you can still get. Not sure how future proof this will be though with future support from NVIDIA (you still need CUDA for offloading). I have not yet had success with any consumer AMD graphics product, the gcn backend requires the radeon instinct compute cards. So I suppose any "cheap" nvidia will do, of course performance wise it will suck (esp. when doing FP64 - also watch out if they eventually disable that completely on some consumer card generations) Richard. > Note, I've mostly used FreeBSD over the last 25+ years. > I suspect that pursuing offloading may be easier with > a flavor linux.
