A friend of mine used to work for a GPU database startup as an integration engineer. He got frustrated because GPU drivers ( not just AMD but also Nvidia ) are intrinsically unstable and not designed for long flawless runs. If a few bits have a wrong value in a deep neural network or a pixel is wrong in a game, it does not matter much. In databases ( or file systems for that matter ) it does mean everything! It is hard to believe at first, but his former company now offers solutions without GPU acceleration that simply work, but they also lost their USP.
