Can the Radeon RX 7900 XTX Run Llama 3.2 3B?

Runs

Yes. Llama 3.2 3B at Q4_K_M is a 2 GB download (Hugging Face file listing for bartowski/Llama-3.2-3B-Instruct-GGUF), and the Radeon RX 7900 XTX has 24 GB of VRAM, leaving about 22 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 Llama 3.2 3B need?

The Q4_K_M file is 2 GB. Add roughly 1.5 GB for the runtime and an ~8K-token context, so about 3.5 GB of VRAM holds it comfortably. Longer contexts grow the KV cache and need more.

What is the fastest Llama 3.2 3B can generate on the Radeon RX 7900 XTX?

Generation reads every weight once per token, so the Radeon RX 7900 XTX's 960 GB/s of memory bandwidth divided by the 2 GB file sets a ceiling near 475 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.
