What the gemma-3-12b-it numbers mean

The fastest verified result on our board is 39.4 output tok/s on an RTX 3060 x2 at Q4_K_M with a 512-token context. That is about 25.4 ms per generated token — 500 tokens takes roughly 12.7 seconds. Prompt processing on the same record runs at 1275.9 tok/s, so a 2,000-token prompt is read in about 1.6 seconds. Peak VRAM was measured at 8.5 GB.

How much VRAM does gemma-3-12b-it need?

gemma-3-12b-it has 12.0B parameters. These estimates use the same formula as the VRAM calculator: weights, plus about 15% for a moderate-context KV cache and runtime overhead, plus a small engine floor.

Q4_K_M (4-bit)8.6 GB12 GB
Q8_0 (8-bit)15.5 GB24 GB
FP16 (16-bit)28.4 GB48 GB

Long contexts and large batches raise the real number — read the smallest card as "possible with a reduced context". Measured throughput is on the benchmark board.
