Question 1

Can I run Llama 3.2 3B on a AMD Radeon RX 7800 XT?

Accepted Answer

Yes — AMD Radeon RX 7800 XT runs Llama 3.2 3B fully on GPU at the FP16 quantization. Full GPU inference — 16 GB VRAM meets the 10 GB recommendation.

Question 2

What quantization of Llama 3.2 3B should I use on a AMD Radeon RX 7800 XT?

Accepted Answer

For 16 GB VRAM on the AMD Radeon RX 7800 XT, the FP16 variant is the best fit. Estimated ~97.5 tokens/sec on the FP16 quantization.

Question 3

How fast does Llama 3.2 3B run on AMD Radeon RX 7800 XT?

Accepted Answer

Roughly 97.5 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 7800 XT is not enough for Llama 3.2 3B?

Accepted Answer

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

Quantization	File Size	Min VRAM	Rec VRAM	Context	Verdict	Estimated tok/s
Q4_K_M	2 GB	3 GB	4 GB	8K / 128K	Full GPU	~249.6
Q8_0	3.4 GB	4.5 GB	6 GB	8K / 128K	Full GPU	~174.8
FP16Best fit	6.4 GB	7.5 GB	10 GB	8K / 128K	Full GPU	~97.5
