Highlighted cells indicate the stronger value in that row (higher is better). Scores and model fit are transparent heuristics for relative guidance, not benchmarks.
Bottom line
The NVIDIA H100 (80GB) leads on our computed Local AI Score (91/100 vs the NVIDIA A100 80GB's 72/100), making it the stronger pick for demanding local AI. Its largest comfortably-runnable model is Qwen2.5 72B (Q4_K_M). The NVIDIA A100 80GB remains the leaner, lower-overhead option where its score is enough.
Overall lead by Local AI Score: NVIDIA H100 (80GB).
Pick the NVIDIA A100 80GB if a leaner, lower-cost setup is enough (72/100), you need to run models up to Qwen2.5 72B (Q4_K_M), you want an always-on, on-prem deployment — it suits the Business AI Business OS tier.
Pick the NVIDIA H100 (80GB) if you want the higher Local AI Score (91/100), you need to run models up to Qwen2.5 72B (Q4_K_M), you want an always-on, on-prem deployment — it suits the Enterprise AI Business OS tier.
