Google TPU: From “Internal Secret Weapon” To An AI Weapon That Can Shake NVDA? Google TPU is a dedicated accelerator that Google built in‑house for AI. It started out being used only for internal services, and has now become both a cloud product and an independent AI chip business, changing the rules of the entire AI infrastructure game. In this process, TPUs both help Google lower the cost of its own AI, and at the same time move toward external sales and cloud supply, posing a substantial long‑term threat to Nvidia, which almost monopolizes AI chips today, and potentially making future AI products “cheaper, more power‑efficient, and more everywhere.” What Is A TPU, And Why Does Google Need Its Own Chip? A TPU (Tensor Processing Unit) is not a general‑purpose GPU. It is an ASIC chip designed for deep‑learning core workloads such as matrix multiplication and vector operations, and is especially friendly to today’s Transformer‑based models like Llama a...
