Well this also shows their commitment to Tensorflow if they willing to pay to fab custom chips for it. Then again, in the Google scheme of things that's probably not a huge cost.

They've probably carefully modeled the energy savings over GPU/FPGA and found it to be substantial enough, even taking into account costs of design changes.

If you need enough chips it doesn't take particularly careful modelling to say that you'll beat an FPGA quite substantially in most cases.
