Nextbigfuture talked to an attendee of 2017 Google IO and he reported that Google will be putting mini versions of the second generation TPU (tensor processing unit) into all new google cellphones.
The TPU is optimized for artificial intelligence and deep learning. The new TPU has 180 teraflops of processing power.
It was not revealed how powerful the mini versions would be but they would need to use less power and no cooling.
The server versions use about 80 watts of power and have cooling units that were very tall.
