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 QAT 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 QAT 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 QAT 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.

A B200 is the fastest we calculate for it: about 282 tokens per second, from 8,000 GB/s of memory bandwidth.

Background

Gemma 3 QAT 12B was published by Google DeepMind, in United States of America, in April 2025. The organisation is categorised as 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 Gemma 3 12B, 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.

Reading the throughput figures

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

Every weight participates in every token here, so bandwidth is the whole story: the ranking below is effectively a ranking of memory throughput.

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

Step by step

How to choose a GPU for Gemma 3 QAT 12B

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

01

Read the memory figure first

The table lists every card that can hold Gemma 3 QAT 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

The conversation occupies memory too, and grows as it goes. Set the slider to the length you expect: at long context Gemma 3 QAT 12B can slip off a card that handles short questions easily.
03

Set a quality floor

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

Rank by throughput rather than spec sheet

Sort by speed to see how cards rank for Gemma 3 QAT 12B. It will not match a gaming ordering — generation is bound by memory bandwidth, which is why the B200 tops it at 282 tok/s.
05

Check the fit verdict before buying

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

See what else that card runs

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

Answers

Gemma 3 QAT 12B — common questions

Can I run Gemma 3 QAT 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 QAT 12B open source?

Its weights are published, so Gemma 3 QAT 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 QAT 12B have?

Gemma 3 QAT 12B has 12B parameters. 12B. 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 QAT 12B?

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

When was Gemma 3 QAT 12B released?

Gemma 3 QAT 12B was published in April 2025.

What is Gemma 3 QAT 12B used for?

Gemma 3 QAT 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. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

Where can I download Gemma 3 QAT 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.

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

Only by offloading, which is usually a false economy: the part in system memory drags the whole thing down — the nearest miss we calculate is short by 2.6 GB. Our figures for Gemma 3 QAT 12B assume it is fully resident.

Would two GPUs run Gemma 3 QAT 12B faster?

A second card roughly doubles the memory available but not the generation rate. With 509 cards already able to run Gemma 3 QAT 12B alone, the case for pairing is weak.

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

Each card is shown running the least-compressed copy it can hold, and Gemma 3 QAT 12B appears at 4 different compression levels across the cards that fit it. Bigger cards get the more accurate version.

How accurate are these Gemma 3 QAT 12B speed estimates?

Every figure is derived from memory bandwidth and model size, not benchmarked. That is why each is published as a range such as 240–339 tok/s on the B200 rather than a single number.

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

The smallest card in our catalogue that holds Gemma 3 QAT 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 QAT 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 QAT 12B clear that.

How much VRAM does Gemma 3 QAT 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 QAT 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 QAT 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 QAT 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.
