Which local LLMs can the GeForce RTX 4090 run?

Assumes 32 GB of DDR5-5600 system RAM, Windows with this GPU driving the display, 8k context and an f16 KV cache.

What to expect from the GeForce RTX 4090

The RTX 4090 has the same 24GB as the GeForce RTX 3090, so the same models fit; what it adds is speed, with 1,008 GB/s of memory bandwidth and much more compute. Qwen3 32B shows the difference. It stays fully on the GPU at Q4_K_M on both cards, but it thinks before answering, so CanRun holds it to a stricter speed bar, and it runs great here but only well on that card. Mixture-of-experts models such as Qwen3 30B-A3B fit completely and run great; our page for Qwen3 30B-A3B (2507) on the GeForce RTX 4090 has the details. Nemotron 3.5 Lightning 30B-A3B just misses 24GB, though, and keeps some experts in system RAM.

The limits are the same as on any 24GB card. Llama 3.3 70B at Q4_K_M needs 45.2 GB and is too slow when split with system RAM. gpt-oss-120b needs 64GB of system RAM to load, and then runs slowly with its experts in RAM, a theoretical estimate (±30%).

The GeForce RTX 4090 Laptop is a different card with 16 GB of VRAM, so it lands in the 16GB tier: Gemma 4 31B runs great on this card but only slowly on the laptop.

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.

Models with a thinking mode spend extra tokens thinking, so their speed thresholds are 1.5× stricter (30 / 12 / 3 tok/s). With thinking turned off, a model may do one grade better.

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. 155.9 tok/s (124.7–187.1, calibrated estimate ±20%).

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

At Q4_K_M with 8k context, out of 59 tracked models: 47 run great, 2 run well, 0 run slowly and 10 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.
