Gemma 4 12B (Unified) on the NVIDIA GeForce RTX 5080: VRAM by quantization

Quant	VRAM needed	Fits 16 GB?	Max context
F16	28.6 GB	✗ No	—
Q8_0	17.4 GB	✗ No	—
Q6_K	14.5 GB	✓ Yes	4K
Q5_K_M	13.1 GB	✓ Yes	4K
Q4_K_M	11.9 GB	✓ Yes	8K
Q3_K_M	9.8 GB	✓ Yes	8K
Q2_K	8.6 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 16 GB. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
