Brain vs H100 physical ledger: 80B transistors against 86B neurons
yaroslavvb · x · 2026-09-24
Yaroslav Bulatov compiled a "numbers you should know" comparison between the human brain and an H100 GPU: roughly 80B transistors on the chip versus 86B neurons in the brain, with the number of transistor flips being on the same order as synaptic arrivals. He published the ledger as an AI-agent-readable spacesheep page, offering a concrete physical anchor for debates on how far compute is from the brain.
