           | Yes and no. AMD uses different architectures for their
           | consumer grade hardware and their HPC stuff as well (i.e.
           | RDNA vs. CDNA).
           | 
           | CUDA support (or rather lack thereof, which isn't AMD's
           | fault) plays a major role w.r.t. software support, but AMD's
           | compute architecture isn't DL-focused either.
           | 
           | The MI250X compute part for example has a FP16 to FP32 ratio
           | of 8:1 and a FP32 to FP64 ratio of 1:1; in other words it's
           | an absolute beast at GPGPU compute.
           | 
           | The 6900XT on the other hand has a FP16 to FP32 ratio of just
           | 2:1 and a FP32 to FP64 ratio of 1:16 (i.e. it's severely
           | restricted at high precision workloads and OK at half-
           | precision).
           | 
           | Comparing this to the specs of NVIDIA cards, they're still
           | _vastly_ superior on paper. The consumer versions of Ampere
           | only get 1:1 (FP16:FP32) and 1:64(!!! FP32:FP64)
           | respectively. But then again, NVIDIA cards feature dedicated
           | "tensor cores", which have no equivalent on AMD consumer
           | grade hardware.
           | 
           | The main selling point for NVIDIA, however, is software
           | support and mindshare. They started to buy themselves into
           | academia in the late 2000s by sponsoring labs and providing a
           | vast ecosystem of software libraries for deep learning and
           | GPGPU support in general. This not only helped kickstarting
           | the deep learning revolution but also tied their hardware and
           | brand name to GPGPU, which basically became synonymous with
           | CUDA at that point.

           | Of course miners can't do that because mining gear (i.e.
           | GPUs, ASICs, FPGAs, whatever) is hard to purchase and
           | electricity isn't infinite.
           | 
           | But that doesn't stop miners from trying. I know people that

           | the Internet, they buy whole systems that have GPUs, rip out
           | the GPU and sell the system, they've signed up for every GPU
           | manufacturer's wait list, they stalk Microcenter, whatever
