AMD chips have almost always had a lead over Nvidia from a per-flops perspective, and AMD's architecture is definitely ahead of Nvidia as far as supporting integer operations and bitwise ops efficiently(see their dominance of cryptocurrency mining). However, Nvidia's software tooling has always been superb, and they basically own the GPGPU-for-HPC space because of it. On top of that, one of the biggest growth areas of consumers of GPGPU in recent years has been "deep learning", for which Nvidia has embraced and has great tooling and software for their hardware. AMD has potential to compete with Nvidia in this area, but they don't seem to have the resources to develop optimized Neural Network software to run on their GPUs like Nvidia does, so they are way behind. Basically, GFLOPS per Watt is nice and all, but if nothing you care about runs on the hardware, you won't buy it. AMD seems to have been stuck in this position for HPC, and it doesn't seem to be changing sadly.
