How to read the verdicts

Runs great
Fully on the GPU at 20 tok/s or more
Runs well
Fully on the GPU at 8–20 tok/s; MoE experts in system RAM at 20 tok/s or more; or at least 90% on the GPU at 8 tok/s or more
Runs slowly
2–8 tok/s; CPU-only; less than 90% on the GPU; or MoE experts in system RAM below 20 tok/s
Won't run
Does not fit, or under 2 tok/s

Every model on the GeForce RTX 4090

Dense models split between GPU and CPU slow down sharply — the CPU side sets the pace. MoE models that keep only their experts in system RAM degrade far more gently.

Frequently asked questions

What is the largest model that runs entirely on the GeForce RTX 4090?

Qwen3.5 35B-A3B at Q4_K_M (a 22.63 GB file) fits entirely in 24 GB with 8k context, at est. 220.6 tok/s (176.5–264.7, calibrated estimate ±20%).

How many local LLMs run well on the GeForce RTX 4090?

At Q4_K_M with 8k context, out of 29 tracked models: 24 run great, 0 run well, 0 run slowly and 5 won't run.

Can the GeForce RTX 4090 run a 70B model like Llama 3.3 70B?

Runs slowly — Partial offload, IQ4_XS: est. 2.2 tok/s (1.8–2.6, calibrated estimate ±20%).

Speeds are estimates from memory bandwidth, calibrated against public benchmarks, and each one comes with an error band and a confidence label. Real results vary with drivers, backend, context length and thermals.
