2026 estimates · inputs through September 1

NVIDIA’s A100 is the most cited GPU in the index’s 2026 NVIDIA-chip series, with 15,327 citations. H100/H200 follows with 9,823, then RTX 4090 with 6,557.

How to read this finding

The 2026 estimates combine counts through September 1 with projections for the second half of the year. These figures measure mentions of hardware used in papers, not sales, installed GPUs, or which chip performs best.
