So correct me if I am wrong but when Google created their TPU the only advantage was inference with high power efficiency . NVIDIAs response on making their own took a year because Xeons are nearly everywhere and can do inference but less efficiently. I imagine since a TPU is a specialized hardware it makes more sense in mobile and then a data center looking at how slow AWS deploys hardware .
