GPUs for running LLMs: specs compared

Memory, bandwidth, dense Tensor throughput and board power of every GPU in the dataset, from the vendor's own datasheet or whitepaper, each with the day it was read. Open a GPU for the open models that fit on it.

Two figures decide most of what a GPU can do with a language model: its memory, which bounds the model and the context it can hold, and its memory bandwidth, which bounds how fast it generates tokens. Tensor throughput matters when many requests are served at once.

The table lists only GPUs with an official vendor source. Tensor figures are dense, without sparsity, so GPUs from different datasheets can be compared; each GPU's page says how its published figures were turned into these.

Every GPU in the dataset

Ordered by memory. A figure read more than 180 days ago is marked stale. Each GPU links to its page.

Reading the table

An H100 SXM and an H200 SXM have the same Tensor throughput, but the H200 SXM has 141 GB at 4,800 GB/s against 80 GB at 3,350 GB/s: it holds larger models and generates faster on the same model.

Limits

  • Datasheet figures, not measurements: real throughput depends on the engine, the kernels and the workload.
  • NVIDIA GPUs only, as the dataset holds them today; a GPU without an official source has no page.
  • No price, availability or offer is part of these pages.
