Google's Custom Silicon Advantage: How TPU v7 Creates Cost Gravity Across the Entire Stack
This analysis is part of Google's AI Full-Stack Domination , a deep dive by The Business Engineer.
Key Components
TPU v7 Ironwood
Ironwood is approaching general availability. Validation is extraordinary: Anthropic is committed to access up to 1 million TPUs , and 9 of the top 10 AI labs now choose Google…
The 78% Number
Gemini serving costs dropped 78% in 2025 , driven by model optimizations running on proprietary hardware.
The Compounding Loop
Invest in custom silicon → 78% cost reduction compounds → every product gets cheaper → more revenue → more chips → repeat.

Key Insight
Gemini serving costs dropped 78% in 2025 , driven by model optimizations running on proprietary hardware. That single number explains more about Alphabet's strategic position than any revenue figure.
Everything in Google’s AI stack starts with chips. Google designed TPUs specifically for its own AI workloads, giving it a 2-3 year design iteration advantage over companies dependent on NVIDIA’s allocation cycles.
TPU v7 Ironwood
Ironwood is approaching general availability. Validation is extraordinary: Anthropic is committed to access up to 1 million TPUs, and 9 of the top 10 AI labs now choose Google Cloud infrastructure — as explored in the economics of AI compute infrastructure — . This is not a commodity chip business—it’s a vertically integrated compute layer where hardware is co-optimized with JAX and TensorFlow.
The 78% Number
Gemini serving costs dropped78% in 2025, driven by model optimizations running on proprietary hardware. That single number explains more about Alphabet’s strategic position than any revenue figure. When your foundation gets 78% cheaper in one year while competitors pay market rates for GPU access, every product built on top carries a structural margin advantage.
The Compounding Loop
Invest in custom silicon → 78% cost reduction compounds → every product gets cheaper → more revenue → more chips → repeat. CapEx going from $91B (2025) to $175B+ (2026) isn’t excessive spending. It’s scaling the foundation that makes everything above it cheaper.
The silicon layer creates the cost gravity that pulls margins upward across the entire stack.
