Can the RTX 3090 Run Qwen3 30B-A3B?
Runs
Yes. Qwen3 30B-A3B at Q4_K_M is a 18.6 GB download (Hugging Face file listing for unsloth/Qwen3-30B-A3B-GGUF), and the RTX 3090 has 24 GB of VRAM, leaving about 5.4 GB for the KV cache and runtime. No published speed measurement for this pair passes SpecPicks' sanity checks yet, so no tokens-per-second figure is quoted.

More about this pair
How much VRAM does Qwen3 30B-A3B need?
The Q4_K_M file is 18.6 GB. Add roughly 1.5 GB for the runtime and an ~8K-token context, so about 20.1 GB of VRAM holds it comfortably. Longer contexts grow the KV cache and need more.
What is the fastest Qwen3 30B-A3B can generate on the RTX 3090?
Qwen3 30B-A3B is a mixture-of-experts model that reads about 2 GB of active weights per token. At the RTX 3090's 936 GB/s of memory bandwidth, that sets a ceiling near 466 tokens per second. Real runs land below it.

How the checks work
The fit is the Q4_K_M file size against the card's VRAM, with 1.5 GB kept for the runtime and an ~8K context. A published run counts only if the pair fits, the run is Q4-class, its source does not call it an estimate, it is under the bandwidth ceiling above, and it is not one figure pasted across many cards. The whole matrix is downloadable as a CSV under CC BY 4.0.
