Qwen 3.5 9B on the NVIDIA GeForce RTX 5070: VRAM by quantization

Quant	VRAM needed	Fits 12 GB?	Max context
F16	21.7 GB	✗ No	—
Q8_0	13.2 GB	✗ No	—
Q6_K	11.1 GB	✓ Yes	4K
Q5_K_M	10.1 GB	✓ Yes	4K
Q4_K_M	9.1 GB	✓ Yes	8K
Q3_K_M	7.5 GB	✓ Yes	8K
Q2_K	6.6 GB	✓ Yes	8K

VRAM needed assumes a 4K-token context with an f16 KV cache; “Max context” is the largest window that still fits in 12 GB. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
