Frequently asked questions about NVIDIA H100 PCIe
Answered from the entry's own figures: memory, which models fit, bandwidth, power and the card's class.
NVIDIA H100 PCIe has 80 GB of HBM3 at 2,000 GB/s. At INT8 a model's weights take about one byte per parameter, so the card holds roughly a 64B-parameter model with room for context; larger models need several cards or a lower precision.
From the catalog's estimates at INT8, Kimi Linear 48B A3B Base, Llama 3_3 Nemotron Super 49B V1, Gemma 4 31B IT and Llama Nemotron Embed Vl 1B V2 fit on a single NVIDIA H100 PCIe with their default context. The list on this page shows the estimated memory each takes; the capacity planner sizes any model against this card for your own context length, batch size and request rate.
2,000 GB/s. Bandwidth bounds how fast a model generates tokens, because every token reads the whole set of weights and the KV cache from memory; at this rate a 64B model at INT8 could be read on the order of 31 times a second on one card, before batching and framework efficiency.
NVIDIA H100 PCIe has a TDP of 350 W, with a maximum of 350 W, in the PCIe form factor. Budget the TDP per card plus host overhead when sizing a server's power and cooling.
NVIDIA H100 PCIe is a datacenter accelerator, meant for servers and multi-GPU serving, built on the Hopper architecture and released in 2022. It supports a multi-GPU interconnect at 600 GB/s, so a model larger than one card can be split across several.
