It's also rather disingenuous to compare TPU2 to Kepler. Based on when it came online, they should've compared it to Pascal.

However, the more interesting comparison is between the TPU and GP102. The latter claims to achieve 45.5 8-bit TOPS, with a nominal TDP of 250 W. So, the original TPU still has 6.7x better efficiency.

Anyway, I wonder why the TPU2 with 32-bit, while everyone else is trying to do inferencing with 16-bit floats.

Eh, I think by now when someone says "HBM" people should know they are referring to HBM2. The first generation is probably not very useful anymore, and could be out of production altogether.
You can also tell by the capacity being larger than 4GB.
