What Is the Ironwood AI Chip?
The Ironwood chip is the newest addition to Google’s proprietary Tensor Processing Units (TPUs). It is specifically engineered for inference tasks, which involve generating responses using pre-trained AI models. This means faster, more efficient handling of user prompts, AI assistants, and machine learning applications.
According to Amin Vahdat, Google Vice President, “The relative importance of inference is going up significantly,” highlighting Ironwood’s key role in Google’s long-term AI strategy.
Key Specifications of the Ironwood Chip
- Primary Function: AI inference (real-time output generation)
- Scalability: Operates in clusters of up to 9,216 chips
- Performance: Delivers 2x performance-per-watt over last year’s Trillium chip
- Memory: Increased capacity for more complex AI workloads
- Deployment: Supports Google’s Gemini AI models and is accessible through Google Cloud
Ironwood vs Previous TPU Generations
- Feature Trillium Chip (2024) Ironwood Chip (2025)
- Performance per Watt Baseline 2x higher
- Optimization Mixed (training/inference) Inference-focused
- Chip Cluster Capability Limited Up to 9,216 chips
- Memory Expansion Moderate Significantly larger
- The Ironwood chip unifies the design elements from past TPU lines by combining high efficiency with robust memory and performance capabilities.
Why Ironwood Matters in the AI Race
While Nvidia continues to dominate the AI chip market, Google’s Ironwood offers a rare and competitive alternative. Built over a decade of R&D investment, the chip is exclusively available through Google’s own services, providing the company greater control over its AI infrastructure.
