More than likely they are testing it on specific server setups with a dedicated GPU handling compute workloads. Think supercomputers and maybe cloud provider setups. That'd make sense if someone in AMD ranked the opportunities by $ value and started working down the list fixing bugs. My anecdotal evidence with an AMD GPU is there are serious problems trying to use a graphics card to run graphics and throwing a few compute tasks at it - because X11 will reliably crash and the kernel graphics driver enters some sort of corrupt state. I think that is a use case that was beyond their design considerations to start with. There is a hint that servers are targeted because they supported linux first with ROCm, and had a very tight support matrix of what OS they expected people to use. Unfortunately, this strategy generates a lot of bad publicity and I'd guess has trouble gaining traction because people can't experiment cheaply with AMD hardware. They're progressing though and even with a dose of cynicism about their wherewithal there is a lot in the pipe that has the potential to take on CUDA. Even APUs are promising.
