Can the Radeon RX 7900 XTX run Qwen3 32B?
Just. Qwen3 32B at Q4_K_M needs about 20.8 GB of the Radeon RX 7900 XTX's 24 GB, running at an estimated 29 tok/s. Keep context short and close other GPU apps.

| Quant | Weights | Needs | Fit | Est. speed |
|---|---|---|---|---|
| Q4_K_M | 19 GB | 20.8 GB | Tight | ~29 tok/s |
| Q5_K_M | 23 GB | 24.8 GB | Too big | - |
| Q8_0 | 34 GB | 35.8 GB | Too big | - |

Estimates. Needs = weights + 1.8 GB for KV cache and runtime at modest context. Speed is single-stream decode scaled from the Radeon RX 7900 XTX's 960 GB/s bandwidth (Estimated from memory bandwidth (llama.cpp decode)). Long contexts need more memory and run slower.

Frequently asked
Quick answers
Can the AMD Radeon RX 7900 XTX run Qwen3 32B?
Just. Qwen3 32B at Q4_K_M needs about 20.8 GB of the Radeon RX 7900 XTX's 24 GB, running at an estimated 29 tok/s. Keep context short and close other GPU apps.
How much VRAM does Qwen3 32B need?
About 19 GB of weights at Q4_K_M, 34 GB at Q8_0 and 64 GB at FP16. Add roughly 1.8 GB for the KV cache and runtime at modest context lengths.
How fast is Qwen3 32B on the Radeon RX 7900 XTX?
Roughly 29 tokens per second at Q4_K_M (single user, llama.cpp-style decode). This is an estimate from the Radeon RX 7900 XTX's 960 GB/s memory bandwidth.
