25. TPU vs GPU/CPU
? Google sums up the benefits of its TPU over
contemporary GPUs and CPUs as follows:
? On our production AI workloads that utilize neural network inference, the TPU is
15x to 30x faster than contemporary GPUs and CPUs.
? The TPU also achieves much better energy efficiency than conventional chips,
achieving 30x to 80x improvement in TOPS/Watt measure (tera-operations [trillion
or 1012 operations] of computation per Watt of energy consumed).
? The neural networks powering these applications require a surprisingly small amount
of code: just 100 to 1500 lines. The code is based on TensorFlow, our popular
open-source machine learning framework.
