Can I run Qwen3 32B on AMD Radeon RX 7900 XTX (24GB)?
Yes. Qwen3 32B runs on AMD Radeon RX 7900 XTX (24GB) at Q4_K_M (~22 GB of ~23 GB usable).
Fits at Q4_K_M (~22 GB of ~23 GB usable) but with little headroom. Close other apps; a smaller context frees a few hundred MB.
That figure is at a 4k context and moves about ±15% as context length changes. AMD Radeon RX 7900 XTX (24GB) leaves ~1 GB of headroom.

- ~24,975M tok
At ~$0.15/kWh and the estimated ~32 tok/s, a million generated tokens costs about $0.46 in electricity. Versus a hosted API at ~$0.5 per million tokens, the ~$999 AMD Radeon RX 7900 XTX (24GB) pays for itself after roughly 24,975 million tokens, so local hardware is mostly a fixed cost, not a per-token one. TDP is the peak draw, so this is an upper bound. Assumptions.

FAQ
Can AMD Radeon RX 7900 XTX (24GB) run Qwen3 32B?
Yes. Qwen3 32B runs on AMD Radeon RX 7900 XTX (24GB) at Q4_K_M (~22 GB of ~23 GB usable).
How much memory does Qwen3 32B need?
It is a tight fit on AMD Radeon RX 7900 XTX (24GB). At Q4_K_M the weights are ~19.8 GB; with KV cache and runtime overhead, budget ~22 GB at a 4k context.
What is the best tool to run Qwen3 32B on Windows?
LM Studio for a simple setup; Ollama (CUDA) for the most speed. AMD GPUs run via Vulkan/ROCm at roughly half CUDA throughput. NVIDIA is the smooth path on Windows.

Weights are measured from GGUF files; KV cache and overhead are computed, so totals can vary ~15% with context and runtime. Any tok/s is a bandwidth estimate. See methodology.
