Frequently asked questions about NVIDIA A100 PCIe 80GB
Answered from the entry's own figures: memory, which models fit, bandwidth, power and the card's class.
NVIDIA A100 PCIe 80GB has 80 GB of HBM2e at 1,935 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 A100 PCIe 80GB 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.
1,935 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 30 times a second on one card, before batching and framework efficiency.
NVIDIA A100 PCIe 80GB has a TDP of 300 W, with a maximum of 300 W, in the PCIe form factor. Budget the TDP per card plus host overhead when sizing a server's power and cooling.
NVIDIA A100 PCIe 80GB is a datacenter accelerator, meant for servers and multi-GPU serving, built on the Ampere architecture and released in 2021. It supports a multi-GPU interconnect at 600 GB/s, so a model larger than one card can be split across several.
