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 1B

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 1B

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

Hardware requirements in practice

Minimum card

Tesla C1080

Memory needed

1.8 GB

Fastest

3,388 tok/s

Gemma 3 QAT 1B reaches a parameter count of 1B. That is small enough that hardware is rarely the obstacle, including on cards several years old. The number of cards we track that can run it: 818.

The entry point is Tesla C1080, with a memory capacity of 4 GB, running it at a compression of Q8_0 and producing around 36.9 tokens per second.

The fastest we calculate for it is B200, generating roughly 3,388 tokens per second on the strength of a memory bandwidth of 8,000 GB/s.

Where it came from

Gemma 3 QAT 1B was published by Google DeepMind, in the country recorded as United States of America, during April 2025. It comes out of an organisation categorised as industry.

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

Rather than being trained from scratch, it is derived from Gemma 3 1B. Most models at this scale are adapted from an existing base rather than built from nothing.

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. On Hugging Face it is published under the organisation google.

Understanding the speeds

Half the cards that hold it manage more than 95.1 tokens per second. Producing text faster than most people read it: 806 of them.

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.

Its attention layout is on file, so the memory figures are computed exactly rather than approximated.

Step by step

How to choose a GPU for Gemma 3 QAT 1B

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 able to hold Gemma 3 QAT 1B, needing around 1.8 GB at a compression of Q8_0. No amount of processing power compensates for a card that cannot hold it.
02

Match the context to your actual use

Set the context to what you will actually use. The cache grows with the conversation, and it is the usual reason a card that seemed fine stops fitting Gemma 3 QAT 1B.
03

Set a quality floor

Compression is what makes a model fit smaller cards, at some cost in accuracy, reaching a compression of Q8_0 on the smallest card that fits. Setting a minimum quality drops the cards that only manage it by squeezing further than you would want, and holds the comparison at one level.
04

Rank by throughput rather than spec sheet

Ranking by tokens per second follows memory bandwidth rather than core counts, for Gemma 3 QAT 1B. It will not match a gaming ordering, because generation is bound by memory bandwidth. The card topping the list is B200, at 3,388 tok/s.
05

Check the fit verdict before buying

Tight means it loads and works with no room to raise the context later, in the case of Gemma 3 QAT 1B. Comfortable means you can grow the context later. That difference matters more than a few tokens per second, so buy for comfortable if you expect to.
06

Open the card you have settled on

Every card name links to its own page, which runs the same calculation across the whole model catalogue. A card is usually bought for more than one model, so it is worth a look before buying for Gemma 3 QAT 1B.

Answers

Gemma 3 QAT 1B — common questions

Gemma 3 QAT 1B— who created it?

It was published by Google DeepMind, based in United States of America, an organisation categorised as industry.

Gemma 3 QAT 1B— when was it released?

It was published in April 2025.

Gemma 3 QAT 1B— what is it used for?

It works in the domain of Language, Vision, Multimodal, and is recorded as handling the task of 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.

Gemma 3 QAT 1B— where can I download it?

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

Gemma 3 QAT 1B— can I run it if it does not fit in my GPU?

It can be split between the card and system memory, but it generates painfully slowly that way. Every figure here assumes the whole model is resident on the card.

Gemma 3 QAT 1B— would two GPUs run it faster?

Two cards buy memory rather than speed, which matters only if one card cannot hold it. The number that can: 818. So a second card is rarely the answer here.

Gemma 3 QAT 1B— why does the quantisation differ between cards?

A larger card holds a more accurate copy. The number of compression levels used across the cards that run it: 1. Bigger cards get the more accurate version, and the quality floor above pins the comparison to one level.

Gemma 3 QAT 1B— how accurate are these speed estimates?

They are calculated from specifications rather than measured, and each carries a range. One example: 2,880–4,066 tok/s on B200. The same model and card vary by thirty to fifty per cent depending on the inference software and its version.

Gemma 3 QAT 1B— what GPU do I need to run it?

The smallest card in our catalogue that holds it is Tesla C1080, with a memory capacity of 4 GB. It runs the model at a compression of Q8_0 using about 1.8 GB, and produces roughly 36.9 tokens per second. The number of cards able to run it in total: 818.

Gemma 3 QAT 1B— how fast is it on a GPU?

It depends on the card. The quickest we calculate is B200, at about 3,388 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and the number of cards clearing that: 806.

Gemma 3 QAT 1B— how much VRAM does it need?

It needs about 1.8 GB at a compression of Q8_0, 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.

Gemma 3 QAT 1B— can I run it on a GPU holding 8 GB?

Yes. The card CMP 170HX 8 GB, holding 8 GB, runs it at a compression of Q8_0, using about 1.8 GB and generating roughly 631 tokens per second. The fit is comfortable.

Gemma 3 QAT 1B— can I run it on a GPU holding 12 GB?

Yes. The card GeForce RTX 3080 Ti, holding 12 GB, runs it at a compression of Q8_0, using about 1.8 GB and generating roughly 386 tokens per second. The fit is comfortable.

Gemma 3 QAT 1B— can I run it on a GPU holding 16 GB?

Yes. The card Tesla V100 SXM2 16 GB, holding 16 GB, runs it at a compression of Q8_0, using about 1.8 GB and generating roughly 479 tokens per second. The fit is comfortable.

Gemma 3 QAT 1B— can I run it on a GPU holding 24 GB?

Yes. The card GeForce RTX 5090 D V2, holding 24 GB, runs it at a compression of Q8_0, using about 1.8 GB and generating roughly 568 tokens per second. The fit is comfortable.

Gemma 3 QAT 1B— is it open source?

Its weights are published, so it 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.

Gemma 3 QAT 1B— how many parameters does it have?

It has a parameter count of 1B. 1B. 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.
