: This NVIDIA vs Google TPU – The biggest AI hardware war of 2026

· Google's self-made TPU chips are emerging as a strong competitor to NVIDIA's GPUs. This is due to their lower potential cost and better energy efficiency, which can reduce their total cost of ownership (TCO).

· Investors' sentiment has shifted rapidly. Companies associated with the TPU supply chain, such as Broadcom, Celestica, and TTM Technologies, are performing much better compared to companies that are more reliant on NVIDIA. This is due to the expectations of widespread deployment of TPUs.

· In the future of AI hardware, controlling energy usage and the cost per token are critical factors that can give companies a competitive edge.

· TPUs, being chips designed for specific tasks, save more energy compared to NVIDIA's more general hardware and are potentially cheaper. This could lead to a significant shift, especially as Google considers selling TPUs to external buyers like Meta. This internal device could turn into a major commercial business.
