Basically it means that AMD is now a possible contender for the rather large market of basically scientific researchers and private industry who have CUDA based/oriented software to do ‘AI’ driven development or research on huge banks of GPUs.

Probably this initial implementation still has some kinks to iron out, but it could eventually result in Nvidia not having a functional monopoly in that market.

Also its neat from a hobbyist perspective if youre looking to do some kind of small version of CUDA based stuff along the same lines.
