We announced the TPU last year and recently followed up with a detailed study of its performance and architecture. In short, we found that the TPU delivered 15–30X higher performance and 30–80X higher performance-per-watt than contemporary CPUs and GPUs. These advantages help many of Google’s services run state-of-the-art neural networks at scale and at an affordable cost. In this post, we’ll take an in-depth look at the technology inside the Google TPU and discuss how it delivers such outstanding performance.
