I'm looking to build a PC for deep learning will tensoflow work on amd GPU with the same speed as on nvidia ones as amd doesn't have tensorcore or cuda cores but it will have 16gb of hbm vram his much do the tensor cores impact training
It is difficult to make a broad statement about which hardware acceleration product has the best performance for deep learning until some comparative metrics using the same algorithms and data sets are published, which requires the availability of both products. It's anyone's guess from the below spec comparison. The information on the net is and could only be conjecture at this point.
