The benchmarking posts were about the previous-generation TPUs, which are detailed in an ISCA paper this year: https://drive.google.com/file/d/0Bx4hafXDDq2EMzRNcy1vSUxtcEk/view https://drive.google.com/file/d/0Bx4hafXDDq2EMzRNcy1vSUxtcEk... The previous TPU was aimed at inference. The Cloud TPUs do training. But you're right - I haven't seen any publications about training performance yet. But they'll be available in cloud (currently in alpha), and once they go GA, I'd expect to see a raft of benchmarks by third parties. I can't wait. :)
