Frequently asked questions

How much GPU memory does Gemma 3 27B need?

The weights take 54.9 GB at the native BF16 precision (54.9 GB at BF16, 27.4 GB at FP8, 15.4 GB at INT4). Each concurrent stream adds 496 KB of KV cache per token: 0.8 GB at 4,096 tokens and 3.1 GB at 32,768 tokens.

What is the bare minimum to run Gemma 3 27B?

1 x Instinct MI350X OAM at BF16 with 4,096 tokens of context and one stream. The cheapest live rental for that footprint is 1 x RTX PRO 6000 Blackwell Max-Q Workstation Edition at $0.50 per hour.

How many H100s do you need to run Gemma 3 27B?

one H100 at BF16 for 4,096 tokens of context and one stream. For 32,768 tokens and 32 concurrent streams the tensor-parallel group is 4 H100s, and 1,000 tokens per second takes 4 H100s across 1 replicas.

How much does Gemma 3 27B cost per million tokens on an H100?

About $1.06 per million output tokens at BF16, 32,768 tokens of context and 32 streams, using the cheapest live on-demand price of $1.79 per GPU-hour. The cheapest part per token is 2 x RTX PRO 6000 Blackwell Max-Q Workstation Edition at $0.53.

What precision does Gemma 3 27B ship in?

The published checkpoint is BF16. FP8 and INT4 figures describe post-training quantisations that halve and quarter the footprint at a small accuracy cost.

All figures are roofline estimates from the model's config.json and each GPU's published memory, bandwidth and tensor-core peak, with fixed efficiency factors. Prices are the cheapest live on-demand listing per GPU when the site has one. They are a planning floor; a tuned serving stack can do better. One layer in six attends globally; the rest use a 1,024-token sliding window. The Google repo is gated; geometry read from the unsloth mirror.
