China has ~12% of global AI-relevant compute
China has managed to maintain about 12% of the world's AI-relevant compute.
What AI 2027 Predicted
The scenario states that by mid-2026, China has “managed to maintain about 12% of the world’s AI-relevant compute” despite US chip export controls. This is presented in the context of China partially offsetting export restrictions through domestic chip production (Huawei Ascend), stockpiling, and smuggling, while still falling significantly behind the US in aggregate compute capacity.
How We Track This
We monitor:
- Epoch AI’s GPU cluster and AI supercomputer datasets
- CSET (Georgetown) estimates of Chinese AI compute capacity
- SemiAnalysis reports on global GPU deployment
- Huawei Ascend production volume estimates
- Industry analysts tracking chip smuggling and stockpile estimates
Current Evidence
Epoch AI Data: Epoch AI’s AI Supercomputers dataset (covering roughly 10–20% of total global AI computing capacity) shows the US hosting the majority of GPU cluster performance, followed by China. While this dataset undersamples the full picture, it provides the best available comparative baseline.
GeoCoded Report: A 2025 analysis synthesizing Epoch AI data estimated China at approximately 14.1% of global AI supercomputer performance, with the US at 74.5%. This is modestly above the 12% figure in the AI 2027 scenario, though the methodology captures only publicly known clusters.
Chinese Domestic Compute Goals: China aims to reach 300 EFLOPS of aggregate computing power by 2025, with AI comprising roughly 35%. Domestic alternatives like Huawei’s Ascend chips are being actively deployed, though production volumes remain limited.
Private Sector Dominance: Epoch AI notes that industry’s share of global AI compute surged from 40% in 2019 to 80% in 2025. Since US hyperscalers dominate the private sector, this trend may further concentrate compute in the US.
Counterevidence & Limitations
- Available data captures only a fraction of global AI compute. Chinese military and classified compute is almost certainly underrepresented.
- The ~14% figure from GeoCoded is based on publicly tracked clusters and may overcount or undercount depending on reporting biases.
- China’s actual compute is hard to measure due to: stockpiled pre-ban chips (estimated in the hundreds of thousands of A100/H100-equivalents), smuggled chips, domestic alternatives, and classified military systems.
- The rapid pace of US datacenter construction (Stargate, etc.) may be diluting China’s share even as China’s absolute compute grows.
- “AI-relevant compute” is not precisely defined — different measures (FP32 vs. FP16 vs. INT8; training vs. inference) give different pictures.
What Would Change Our Assessment
- Upgrade to “on-track”: Updated Epoch AI or CSET estimates placing China at 10–15% of global AI compute by mid-2026
- Upgrade to “confirmed”: Multiple independent estimates converging on ~12% for China’s share at the predicted timeframe
- Downgrade to “behind”: Evidence that US compute buildout is growing much faster than Chinese, pushing China’s share below 10%
- Complicate assessment: Evidence of large hidden Chinese compute (military, classified) that would push the share significantly above 12%
