Introduction
- TL;DR: Google unveiled its 7th-generation AI chip Ironwood in November 2025, achieving 4x to 10x performance improvements over previous chips. Ironwood boasts 4,614 FP8 TFLOPS, 192GB HBM3E memory, 9,216-scale pod architecture, and market-leading efficiency. Anthropic secured access to up to one million Google TPUs in a multi-billion dollar deal, intensifying competition and AI infrastructure scale. The announcement marks Google’s ambitious attempt to outpace Nvidia and Microsoft/OpenAI partnerships in next-gen AI computing.
- Ironwood, the latest Google custom silicon for AI, is engineered for next-gen LLMs, multimodal AI, and massive-scale inference, representing a major leap in hardware for cloud and enterprise AI. This strategic move positions Google as a formidable competitor in the AI infrastructure market, directly challenging the dominance of traditional GPU manufacturers.
1. Ironwood: Core Features and Advancements
1.1. Specs & Architecture
Ironwood (TPU v7) delivers 4,614 FP8 TFLOPS per chip, 192GB of HBM3E memory, 7.37TB/s bandwidth, and scales up to 9,216 chips per superpod via 9.6Tb/s ICI, enabling parallel training and ultra-low-latency inference of large-scale models. Its perf/watt is doubled versus Trillium (v6e) and up to 30x more efficient than the original 2018 TPU. Ironwood’s chief target: LLMs (like Claude), complex RL, and AI serving at massive scale.
IDC estimates show enterprises using Google’s AI Hypercomputer (the system integrating Ironwood) report 353% 3-year ROI, 28% lower costs, and 55% operational gains versus legacy setups.
Why it matters:
This magnitude of step-function efficiency and scale is shaping the cost, speed, and capability of Generation AI, with Google directly challenging Nvidia’s long-time lead.

2.1. Deal Details
Anthropic, a leading Claude LLM company, agreed to a multi-year Google Cloud deal for access to up to one million state-of-the-art Ironwood TPUs, running at more than a gigawatt of compute. The deal is valued at tens of billions USD, positioning Google as Anthropic’s primary compute supplier despite Anthropic’s continued use of Amazon Trainium and Nvidia GPUs as well.
All new TPUs integrate into Google’s AI Hypercomputer/Vertex AI platform, streamlining training and serving on open frameworks like PyTorch/XLA, OpenXLA, and reducing dependence on Nvidia’s platform.
Why it matters:
Securing a dedicated pass to cutting-edge hardware ensures Anthropic’s Claude models stay at the AI frontier, and Google’s competitive stance versus Nvidia and Microsoft strengthens.
3. Industrial Impact & Ecosystem: Practical Deployment
3.1. Adoption Context
Ironwood TPUs are being deployed by tech leaders such as Anthropic (for Claude LLMs) and Lightricks (LTX-2 mmModel). Target workloads include trillion-parameter-scale LLMs, real-time multimodal inference, and enterprise AI transformation. Google aims for cloud infrastructure independence by promoting TPU-first architectures and open source AI stacks, further challenging the historic GPU monopoly.
Why it matters:
The next wave of AI will likely be defined by hardware/software platform alliances, and Ironwood’s launch marks a material acceleration of that trend.

(Thread에서 이어서 쓸 수 있는 추가 요약/팩트 포인트)
- Ironwood는 단순 성능뿐 아니라, HBM3E 메모리·네트워킹·쿨링 등 엔드투엔드에서 혁신이 입증된 첫 TPU다.
- Anthropic 사례처럼, AI 스타트업/프로덕트 대기업 모두 클라우드 TPU 활용 본격화 추세.
- 차세대 LLM·멀티모달 모델이 TPU 특화 환경에서 계속 출현할 가능성 높음.
- 이 계약을 계기로 GPU와 TPU의 시장 점유율 경쟁, 대규모 자본투입 전쟁은 더욱 격화될 것.
