Can the RTX 4090 Run Qwen2.5 32B?
Runs
Yes. Qwen2.5 32B at Q4_K_M is a 19.9 GB download (Hugging Face file listing for bartowski/Qwen2.5-32B-Instruct-GGUF), and the RTX 4090 has 24 GB of VRAM, leaving about 4.1 GB for the KV cache and runtime. Published runs put generation at a median of 34.4 tokens per second across 1 cited measurement. Fastest cited run: DatabaseMart.

More about this pair
How much VRAM does Qwen2.5 32B need?
The Q4_K_M file is 19.9 GB. Add roughly 1.5 GB for the runtime and an ~8K-token context, so about 21.4 GB of VRAM holds it comfortably. Longer contexts grow the KV cache and need more.
What is the fastest Qwen2.5 32B can generate on the RTX 4090?
Generation reads every weight once per token, so the RTX 4090's 1008 GB/s of memory bandwidth divided by the 19.9 GB file sets a ceiling near 51 tokens per second. Real runs land below it; SpecPicks rejects any published figure above 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.
