What LLMs can an RTX 5090 run?

An RTX 5090 gives a model 32 GB of memory and 1,792 GB/s of bandwidth. Of the 40 open models tracked here, 18 fit at Q4_K_M with an 8,192-token context.

Models that fit on one RTX 5090

The most precise weights that still fit with 8K tokens of context and one request, the memory that takes, the longest context at that precision and the writing speed. Bigger models come first.

Too big for one card

How many RTX 5090 cards these need at Q4_K_M in one tensor-parallel group; some need more than 8.

How these numbers are worked out

Memory is the weights at each precision plus the KV cache for 8,192 tokens in FP16 and runtime overhead (0.5 GB plus 10%), computed from each model's files on Hugging Face with the LLM VRAM Calculator. Speed is estimated from memory bandwidth and the parameters read per token with the LLM Speed Calculator. Both tools take any other model from Hugging Face.
