Memory: RTX 3060 12GB has 12 GB. Gemma 4 12B weights are about 7.3 GB at Q4_K_M (11.91B params × 4.89 bits ÷ 8, before context/KV cache). Arithmetic, not a measurement; long contexts need more. Check other quants in the VRAM calculator.
Speeds are decode (generation) tokens/sec as reported by each source; quant, engine and context differ, so small gaps are noise.
