AlphaGoZero runs on 4 TPUs not GPUs. And that is only for inference, not for training. For training it uses 64 GPUs. More importantly, AlphaGoZero is the final evolution. To reach this stage one needs to experiment a lot, and most of the experiments are failures. To do any meaningful research requires a budget of several times or dozens of times the amount of computing power, and this is only for one project. The computation resources at universities are definitely not sufficient.
