Volta. The hardware is good. It's fairly horrendous to program but comparable to other specialised chips and the lowering from XLA / onnx etc worked well enough. The 20x performance lead over Nvidia's Pascal looked great. Volta beating Pascal by 10x did unrecoverable damage to Graphcore's marketing slides. I think they got the later generations running a bit faster but it was never the order of magnitude over nvidia they started from. I'm not sure what they're doing these days. The exit to softbank valued the employee shares at $0 so the engineers that had already left got burned. Most of the engineers I knew there have left but there still seems to be a large headcount.
