Speeds are estimates for a single request — one conversation at a time — calculated from memory bandwidth, model size and quantisation. Real throughput varies with the inference runtime and its version. Figures published by hardware vendors measure many simultaneous requests and are much higher.

The extremes

The ten fastest GPUs that run Gemma 3 12B

Ranked by estimated tokens per second, newest card first where speeds tie. Because generation is bound by memory bandwidth, this ordering follows bandwidth rather than any gaming benchmark.

The smallest GPUs that still run Gemma 3 12B

The cheapest route in, by memory capacity. A tight fit runs the model but leaves nothing spare for a longer conversation.

What the numbers mean

The hardware side

Minimum card

Xeon Phi 5110P

Memory needed

6.6 GB

Fastest

282 tok/s

Gemma 3 12B is small enough at 12B parameters that hardware is rarely the obstacle — 509 of the cards we track can run it, including cards several years old.

At the low end, a Xeon Phi 5110P handles it — 8 GB, at Q3_K_M, for about 19.8 tokens per second.

At the other end, a B200 generates roughly 282 tokens per second on it, on the strength of 8,000 GB/s of memory bandwidth.

What this model is

Gemma 3 12B was published by Google DeepMind, in United States of America, in March 2025. It comes out of industry.

It works in Language, Vision, Multimodal, and is recorded as doing language modeling/generation, Question answering, Translation, Chat, Quantitative reasoning, Visual question answering, Code generation.

It builds on SigLIP 400M, which is why it shares that model's general shape and size.

Published weights mean the model runs on your machine rather than someone else's, which is what makes the hardware question below answerable at all. It is published under the google organisation on Hugging Face.

What decides the speed

The median result is around 21.2 tokens per second; 455 cards produce text faster than most people read it.

It is a dense model, so every parameter is read for every token produced. That makes speed track memory bandwidth almost exactly — a card with twice the bandwidth generates roughly twice as fast.

Because the architecture is recorded, the memory column is derived rather than estimated.

How it was trained

Producing it required around 8.6 × 10²³ FLOP of arithmetic, on Google TPU v4, which is a statement about the training budget rather than about inference.

The training set ran to roughly 12,000,000,000,000 tokens.

Step by step

How to choose a GPU for Gemma 3 12B

The table above has already assessed every card we hold specifications for against this model. Getting to your answer takes six steps.

01

Check what it needs before anything else

The table lists every card that can hold Gemma 3 12B — around 6.6 GB at Q3_K_M. That figure, not the card's headline performance, is what decides whether it runs.
02

Decide how long your conversations run

Longer conversations cost memory on top of what the weights need. Move the slider to your real working length before trusting any row for Gemma 3 12B.
03

Decide how much compression you will accept

The quantisation column varies by card, because a bigger card holds a more accurate copy of Gemma 3 12B — Q3_K_M on the smallest card that fits. Set a floor to hold the comparison at one level.
04

Sort by speed

Ranking by tokens per second for Gemma 3 12B follows memory bandwidth, not core counts, which is why the B200 tops it at 282 tok/s.
05

Look at the headroom, not just the fit

The fit column separates cards that just manage Gemma 3 12B from those with room to spare. Buy for the second if the context might grow.
06

Open the card you have settled on

Each card page repeats this sweep for every model we hold. It answers what else the hardware is good for, beyond Gemma 3 12B.

Answers

Gemma 3 12B — common questions

Can I run Gemma 3 12B if it does not fit in my GPU?

It can be split between the card and system memory, but Gemma 3 12B generates painfully slowly that way — the nearest miss we calculate is short by 2.6 GB. Nothing on this page assumes offloading.

Would two GPUs run Gemma 3 12B faster?

Capacity adds across cards; throughput does not. Since 509 of the cards we track already hold Gemma 3 12B on their own, a second card is rarely the answer here.

Why does the quantisation differ between cards for Gemma 3 12B?

A larger card holds a more accurate copy. Across the cards that run Gemma 3 12B, 4 compression levels are used; the floor control above pins it to one.

How accurate are these Gemma 3 12B speed estimates?

They are calculated from specifications rather than measured, and each carries a range — 240–339 tok/s on the B200, for instance. The same model and card vary by thirty to fifty per cent depending on the inference software and its version.

What GPU do I need to run Gemma 3 12B?

The smallest card in our catalogue that holds Gemma 3 12B is the Xeon Phi 5110P, with 8 GB of memory. It runs the model at Q3_K_M using about 6.6 GB, and produces roughly 19.8 tokens per second. 509 cards in total can run it.

How fast is Gemma 3 12B on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 282 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 455 of the cards that can run Gemma 3 12B clear that.

How much VRAM does Gemma 3 12B need?

About 6.6 GB at Q3_K_M compression, which is what the smallest card that runs it uses. Less compression needs more: the figures in the memory column above are recalculated for each card, because each one holds the least-compressed version it can.

Can I run Gemma 3 12B on a 8 GB GPU?

Yes. A CMP 170HX 8 GB with 8 GB runs it at Q3_K_M, using about 6.6 GB and generating roughly 142 tokens per second — a tight fit.

Can I run Gemma 3 12B on a 12 GB GPU?

Yes. A GeForce RTX 3080 Ti with 12 GB runs it at Q5_K_M, using about 9.4 GB and generating roughly 57.5 tokens per second — a tight fit.

Can I run Gemma 3 12B on a 16 GB GPU?

Yes. A Tesla V100 SXM2 16 GB with 16 GB runs it at Q8_0, using about 13.6 GB and generating roughly 39.9 tokens per second — a tight fit.

Can I run Gemma 3 12B on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q8_0, using about 13.6 GB and generating roughly 47.3 tokens per second — a comfortable fit.

Is Gemma 3 12B open source?

Its weights are published, so Gemma 3 12B can be downloaded and run on your own hardware. Note that open weights is not the same as open source in the full sense — it says nothing about the training data, the training code, or the commercial terms attached.

How many parameters does Gemma 3 12B have?

Gemma 3 12B has 12B parameters. Vision Encoder: 417M Embedding Parameters: 1,012M Non-embedding Parameters: 10,759M. That figure is the total, and it is what decides how much memory the model needs — roughly half a gigabyte per billion at the compression most people use.

Who created Gemma 3 12B?

Gemma 3 12B was published by Google DeepMind, based in United States of America, categorised as industry.

When was Gemma 3 12B released?

Gemma 3 12B was published in March 2025.

What is Gemma 3 12B used for?

Gemma 3 12B works in Language, Vision, Multimodal, and is recorded as handling language modeling/generation, Question answering, Translation, Chat, Quantitative reasoning, Visual question answering, Code generation. A model can carry several of each, so these are the areas it was built for rather than a limit on what it will attempt.

Where can I download Gemma 3 12B?

Its weights are published under the google organisation on Hugging Face. We do not host model files — this site calculates what hardware is needed to run them.

How much compute was used to train Gemma 3 12B?

Around 8.6 × 10²³ FLOP, on Google TPU v4. That measures what producing the model cost and says nothing about how quickly it answers once trained — inference speed comes from memory bandwidth, not from the training budget.
