I hope AMD turns their attention to machine learning tasks soon not just against Intel but NVIDIA also. The new Titan RTX GPUs with their extra memory and Nvlink allow for some really awesome tricks to speed up training dramatically but they nerfed it by only selling without a blower style fan making it useless for multi-GPU setups. So the only option is to get Titan RTX rebranded as a Quadro RTX 6000 with a blower style fan for $2,000 markup. $2000 for a fan.
The only way to stop things like this will be competition in the space.
