Question 1

Can I run StarCoder2 15B on a AMD Radeon RX 6950 XT?

Accepted Answer

Yes — AMD Radeon RX 6950 XT runs StarCoder2 15B fully on GPU at the Q4_K_M quantization. Full GPU inference — 16 GB VRAM meets the 12 GB recommendation.

Question 2

What quantization of StarCoder2 15B should I use on a AMD Radeon RX 6950 XT?

Accepted Answer

For 16 GB VRAM on the AMD Radeon RX 6950 XT, the Q4_K_M variant is the best fit. Estimated ~51.2 tokens/sec on the Q4_K_M quantization.

Question 3

How fast does StarCoder2 15B run on AMD Radeon RX 6950 XT?

Accepted Answer

Roughly 51.2 tokens/sec for Q4_K_M. Real speed depends on context length, backend (Ollama, llama.cpp, LM Studio), and KV cache size.

Question 4

What if AMD Radeon RX 6950 XT is not enough for StarCoder2 15B?

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_MBest fit	9 GB	10.5 GB	12 GB	4K / 16K	Full GPU	~51.2
