What is TPU (Tensor Processing Unit)?
Google's custom AI accelerator chip designed specifically for tensor operations in machine learning workloads.
Definition
A Tensor Processing Unit (TPU) is a custom application-specific integrated circuit (ASIC) developed by Google specifically for accelerating machine learning workloads. Unlike general-purpose GPUs, TPUs are designed from the ground up for the matrix operations that dominate neural network training and inference. TPUs use a systolic array architecture optimized for large matrix multiplications and are interconnected in pods that enable efficient distributed training. Google uses TPUs extensively for training its Gemini models and offers them to developers through Google Cloud. TPU v5p pods can deliver over 100 exaFLOPS of compute.
