Epoch AI estimates that the computing capacity of AI chips sold has grown about 3.3 times per year since 2022, doubling roughly every seven months. It converts different accelerators into H100-equivalents, a common unit based on Nvidia's H100, so their output can be added together. Source.
The quantities are inferred from revenue data, financial disclosures and analyst reports, and count chips sold rather than deployed. Epoch says available compute may differ only on the margin, so the series guides hardware scale but does not measure capacity actually running workloads.
