What Are Google Tensor Processing Units (TPUs)?

Before diving into startup use cases, it’s important to understand what TPUs are and why they matter.

The Origin and Evolution of TPUs

Google introduced TPUs in 2016 as custom application-specific integrated circuits (ASICs) specifically designed to accelerate machine learning workloads. Unlike general-purpose CPUs or even highly parallel GPUs, TPUs are purpose-built for the types of computations common in neural network training and inference—namely, large-scale matrix multiplies and vector operations.

Since their inception, Google has released several generations of TPUs (v1 through v5 as of 2024), each iteration improving performance, scalability, and efficiency. While Google uses TPUs in-house for search, translation, Photos, and more, the company also offers Cloud TPUs as a rentable resource to startups and enterprises via GCP.
