Question 1

Can I run Qwen3 1.7B on a AMD Radeon RX 6600 XT?

Accepted Answer

Yes — AMD Radeon RX 6600 XT runs Qwen3 1.7B fully on GPU at the FP16 quantization. Full GPU inference — 8 GB VRAM meets the 4.4 GB recommendation.

Question 2

What quantization of Qwen3 1.7B should I use on a AMD Radeon RX 6600 XT?

Accepted Answer

For 8 GB VRAM on the AMD Radeon RX 6600 XT, the FP16 variant is the best fit. Estimated ~75.3 tokens/sec on the FP16 quantization.

Question 3

How fast does Qwen3 1.7B run on AMD Radeon RX 6600 XT?

Accepted Answer

Roughly 75.3 tokens/sec for FP16. Real speed depends on context length, backend (Ollama, llama.cpp, LM Studio), and KV cache size.

Question 4

What if AMD Radeon RX 6600 XT is not enough for Qwen3 1.7B?

Accepted Answer

Try a smaller quantization variant or run on CPU + RAM with the trade-off of slower generation.
