China has reported a massive leap in its domestic artificial intelligence (AI) computing power, with official figures suggesting capacity far beyond what is reflected in global benchmarks, raising questions about a potential “dark pool” of hidden compute.According to China’s ministry of industry and information technology (MIIT), the country has reached 1,882 exaflops — or 1,882 quintillion calculations per second.This figure is more than 6,000 times higher than China’s computing power recorded in the Top500 list, a widely used global ranking of supercomputers, reported South China Morning Post.According to the South China Morning Post, experts note that the two metrics are not directly comparable. The Top500 uses stricter standards for general-purpose computing, while China’s figure is based on AI-focused calculations, which count simpler operations and yield significantly higher performance numbers.When adjusted to Top500 standards, China’s capacity would fall to around 120 to 230 exaflops, still far above publicly known levels.
Different metrics, bigger picture
The development suggests that China’s AI infrastructure may be far more advanced than previously understood.The country has also stopped submitting details of its most powerful systems to global rankings amid rising geopolitical tensions and US export controls, according to an expert cited by the South China Morning Post.MIIT Vice-Minister Zhang Yunming said China is building a nationwide, multilayered computing grid to support its AI industry.The system aims to distribute computing power across national and local centres, making it accessible and affordable, especially for smaller businesses.
US comparison and narrowing gap
In contrast, the United States does not publish a single national figure for AI computing power, as most infrastructure is privately owned.Estimates from the Stanford Institute for Human-Centred Artificial Intelligence suggest the US still holds 50–75% of global AI capacity and leads in the number of advanced data centres.Despite this, the gap between the two countries appears to be narrowing. A recent Stanford report found that Chinese AI models are now competing closely with their US counterparts, signalling rapid progress in capability.Growth projections further underline this trend. A report by International Data Corporation and Inspur estimates China’s AI computing capacity will grow at an annual rate of 46% between 2023 and 2028 — more than double the pace of general computing expansion.
