Gemma 3 12B Instruct on the NVIDIA GeForce RTX 5070: VRAM by quantization

Quant	VRAM needed	Fits 12 GB?	Max context
F16	26.3 GB	✗ No	—
Q8_0	15.1 GB	✗ No	—
Q6_K	12.2 GB	✗ No	—
Q5_K_M	10.8 GB	✓ Yes	4K
Q4_K_M	9.6 GB	✓ Yes	8K
Q3_K_M	7.5 GB	✓ Yes	8K
Q2_K	6.3 GB	✓ Yes	16K

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.
