Can the RTX 5090 Run Qwen3 32B at Q6_K?

Runs

Yes. Qwen3 32B at Q6_K is a 26.9 GB download (Hugging Face file listing for unsloth/Qwen3-32B-GGUF), and the RTX 5090 has 32 GB of VRAM, leaving about 5.1 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 32B need?

The Q6_K file is 26.9 GB. Add roughly 1.5 GB for the runtime and an ~8K-token context, so about 28.4 GB of VRAM holds it comfortably. Longer contexts grow the KV cache and need more.

What speed does Qwen3 32B reach on the RTX 5090?

No published run of Qwen3 32B on the RTX 5090 has been cited yet. Generation reads every weight once per token, so the RTX 5090's 1792 GB/s of memory bandwidth divided by the 26.88 GB file puts the theoretical ceiling near 67 tokens per second. That is an upper bound, not a speed estimate: kernel, launch and compute overhead keep real runs below it.

How the checks work

The fit is the Q6_K 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 (memory bandwidth ÷ GB read per token: the whole file for a dense model, only the active experts' weights for a mixture-of-experts model such as gpt-oss-20b or Qwen3 30B-A3B, which is why those can post figures above bandwidth ÷ file size), it is not slower than the same card on a model twice its size, a single run is not slower than the same card on a larger dense model, and it is not one figure pasted across many cards.
