Answer: Last year, Google boasted that its TPUs were 15 to 30 times faster than contemporary GPUs and CPUs in inferencing, and delivered a 30–80 times improvement in TOPS/Watt measure. In machine learning training, the Cloud TPU is more powerful in performance (180 vs. ... 16 GB of memory) than Nvidia's best GPU Tesla V100.
