Google Unveils Ironwood: A Game-Changer in AI Processing

In a significant leap forward for artificial intelligence, Google has introduced its seventh-generation Tensor Processing Unit (TPU), named Ironwood, at the Cloud Next 2025 conference.

This new chip is designed to revolutionize AI applications by focusing on inference tasks—the process of running trained AI models to generate real-time responses.

Unprecedented Performance

Ironwood stands out with its remarkable computational capabilities. When deployed in clusters of up to 9,216 chips, it delivers an astounding 42.5 exaflops of AI compute power, making it over 24 times more powerful than the world’s fastest supercomputer, El Capitan.

Each chip offers 4,614 teraflops of performance, coupled with 192GB of high-bandwidth memory and a bandwidth of 7.2 terabits per second, significantly surpassing its predecessor, Trillium.

Efficiency and Scalability

Beyond raw power, Ironwood excels in energy efficiency, delivering twice the performance per watt compared to Trillium.

Its enhanced Inter-Chip Interconnect allows for seamless communication between chips, facilitating large-scale deployments.

This design is particularly beneficial for running complex AI models like Google’s Gemini, which require substantial computational resources.

Strategic Implications

The launch of Ironwood signifies Google’s strategic shift towards optimizing AI inference, a critical component as AI applications become more prevalent in daily life.

By developing proprietary hardware tailored for specific AI tasks, Google aims to reduce reliance on third-party suppliers and enhance the performance of its AI services.

Ironwood will be available to Google Cloud customers later this year, offering configurations suitable for various scales of AI workloads.

This development positions Google as a formidable competitor in the AI hardware arena, challenging established players like Nvidia.
