I don't get it. A GPU is just a vector co-processor that can run any compatible software application.
Different architectures perforrm differently for different applications, just like a CPU. Mining is not
an singular application but a group of applications (kernels), each with their own performance
profile.

So what is a mining GPU? Does it have more cores to improve compute-bound applications, or a faster
memory interface to improve I/O bound applications? It depends on the algo.

So what features could their be that define a GPU as a mining GPU? Just removing the video ports won't
reduce the cost enough to draw miners, or anyone. to buy it instead of a regular GPU.

I suspect it's just going to be a marketing campaign to miners. They may brand a card as mining vs gaming
but it will only be cosmetic.
