Are H100 and H200 replacing A100 in AI research?

By Nathan Benaich (Air Street Capital)

2026 estimates · inputs through September 1

H100/H200 citations rise from 4,653 in 2025 to a projected 9,823 in 2026. A100 citations remain higher, at 15,266 and a projected 15,327, respectively.

How to read this finding

Hopper is gaining visibility in published research, but these figures do not establish that researchers have replaced their A100 fleets. The 2026 values include second-half projections; the series also groups H100 and H200 together.
