I am a huge AMD supporter and recently bought their stock as well, but in terms of competition to NVIDIA for non-gaming purposes they have lot of ground to cover. NVENC for example is great for video encoding and supported in a lot of video editing programs. I use AMF in ffmpeg but from my understanding, NVENC is faster and with the 3000 series, better quality. Same with CUDA vs ROCm.

It's not just CUDA vs ROCm, ROCm has come a long way and is pretty compelling right now. What they lack is the proper hardware acceleration (e.g tensor cores).

  ROCm has come a long way but still has a long way to go. It still doesn't support the 5700 XT (or at least, not very well) --- only the Radeon Instinct and Vega are supported. You can find salty GitHub threads about this dating to the very start of when Navi was just released: https://github.com/RadeonOpenCompute/ROCm/issues/887#issuecomment-605711172 https://github.com/RadeonOpenCompute/ROCm/issues/887#issueco... And getting ROCm set up is still a buggy experience with tons of fiddling in the deep inner workings of Linux so it is nearly impossible for the average machine learning engineer to use. It is compelling for certain bespoke projects like Europe's shiny new supercomputer, but for the vast majority of machine learning, it is totally unusable. By now in ML world the word "gpu" is synonymous with "nvidia".

    Full disclosure, European here and in our team everyone is found of Linux so not representative of your average MLEngineer. We actually had more issues with nvidia drivers messing up newcomers' machines during updates than with setting up AMD GPUs, but then again n is small (and AMD GPUs were for playing around rather than real work). Still, a Titan Xp has CUDA support and plenty of memory, but it's better, IME, to upgrade to a model with less memory but higher cuda compute and access to tensor cores.

  Does ROCm even support Navi yet? For the amount invested in the hardware development, the amount AMD have been investing in the software side has been shocking.

H265 quality on AMD's encoder is excellent (has been since it appeared back in Polaris), since Navi it can do 4K60. H264 is not as good but totally usable.
