H100 80GB SXM5 vs V100 16GB PCIe for Local LLMs

The H100 80GB SXM5 has about 272% more memory bandwidth (3,350 vs 900 GB/s). Batch-1 decode tracks bandwidth closely, so a model that fits both cards should decode roughly 272% faster on the H100 80GB SXM5. The H100 80GB SXM5 fits more of the catalog at Q4/8K — 55 vs 25 of 73 models (80 vs 16 GB VRAM). Largest model that fits the H100 80GB SXM5 but not the V100 16GB PCIe: Mistral-Medium-3.5-128B (128.0B). MSRP is $30,000 for the H100 80GB SXM5 vs $8,000 for the V100 16GB PCIe. MSRP is a launch list price, not live retail — Amazon prices move; click through for the current price. Not retail-shoppable: H100 80GB SXM5, V100 16GB PCIe (datacenter-class; cloud rental is the realistic way to use it). In the Q4/8K head-to-head below (49 shared models), the H100 80GB SXM5 posts the higher tok/s in 49 rows vs 0. Methodology.
