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 for Gemma 3 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 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

What it takes to run this model

Minimum card

Tesla C1080

Memory needed

1.8 GB

Fastest

3,388 tok/s

Gemma 3 1B is small enough at 1B parameters that hardware is rarely the obstacle — 818 of the cards we track can run it, including cards several years old.

The smallest card that holds it is the Tesla C1080 with 4 GB, running it at Q8_0 and producing around 36.9 tokens per second.

The quickest result comes from a B200 at around 3,388 tokens per second — its 8,000 GB/s of bandwidth is what buys that.

Background

Gemma 3 1B was published by Google DeepMind, in United States of America, in March 2025. industry is the category the publisher falls under.

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

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

The weights are published, so it can be downloaded and run on your own hardware indefinitely, offline, with no account attached. It is published under the google organisation on Hugging Face.

Reading the throughput figures

Across every card that can run it, the middle of the range is about 95.1 tokens per second, and 806 of them clear the ten tokens per second that roughly matches reading speed.

Being dense, it reads all of itself per token, which is why the ordering by speed below follows the ordering by memory bandwidth so closely.

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

What went into building it

Producing it required around 1.2 × 10²² FLOP of arithmetic, on Google TPU v5e, which is a statement about the training budget rather than about inference.

Around 2,000,000,000,000 tokens went into training it.

Step by step

How to choose a GPU for Gemma 3 1B

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

01

Start from the memory column

Every card here has been checked against Gemma 3 1B — around 1.8 GB at Q8_0. Capacity is the gate — a card either holds it or it does not.
02

Set the context length you will work at

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 1B.
03

Choose how far you will compress it

The quantisation column varies by card, because a bigger card holds a more accurate copy of Gemma 3 1B — Q8_0 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 1B follows memory bandwidth, not core counts, which is why the B200 tops it at 3,388 tok/s.
05

Check the fit verdict before buying

The fit column separates cards that just manage Gemma 3 1B from those with room to spare. Buy for the second if the context might grow.
06

Check the card from the other side

Each card page repeats this sweep for every model we hold. It answers what else the hardware is good for, beyond Gemma 3 1B.

Answers

Gemma 3 1B — common questions

How much compute was used to train Gemma 3 1B?

Around 1.2 × 10²² FLOP, on Google TPU v5e. 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.

Can I run Gemma 3 1B 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. Our figures for Gemma 3 1B assume it is fully resident.

Would two GPUs run Gemma 3 1B faster?

A second card roughly doubles the memory available but not the generation rate. With 818 cards already able to run Gemma 3 1B alone, the case for pairing is weak.

Why does the quantisation differ between cards for Gemma 3 1B?

Each card is shown running the least-compressed copy it can hold, and Gemma 3 1B appears at 1 different compression levels across the cards that fit it. Bigger cards get the more accurate version.

How accurate are these Gemma 3 1B speed estimates?

These are estimates with real error bars. The fastest result here, 2,880–4,066 tok/s on the B200, could reasonably land anywhere in its published range depending on which runtime you use.

What GPU do I need to run Gemma 3 1B?

The smallest card in our catalogue that holds Gemma 3 1B is the Tesla C1080, with 4 GB of memory. It runs the model at Q8_0 using about 1.8 GB, and produces roughly 36.9 tokens per second. 818 cards in total can run it.

How fast is Gemma 3 1B on a GPU?

It depends on the card. The quickest we calculate is a 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 806 of the cards that can run Gemma 3 1B clear that.

How much VRAM does Gemma 3 1B need?

About 1.8 GB at Q8_0 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 1B on a 8 GB GPU?

Yes. A CMP 170HX 8 GB with 8 GB runs it at Q8_0, using about 1.8 GB and generating roughly 631 tokens per second — a comfortable fit.

Can I run Gemma 3 1B on a 12 GB GPU?

Yes. A GeForce RTX 3080 Ti with 12 GB runs it at Q8_0, using about 1.8 GB and generating roughly 386 tokens per second — a comfortable fit.

Can I run Gemma 3 1B on a 16 GB GPU?

Yes. A Tesla V100 SXM2 16 GB with 16 GB runs it at Q8_0, using about 1.8 GB and generating roughly 479 tokens per second — a comfortable fit.

Can I run Gemma 3 1B on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q8_0, using about 1.8 GB and generating roughly 568 tokens per second — a comfortable fit.

Is Gemma 3 1B open source?

Its weights are published, so Gemma 3 1B 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 1B have?

Gemma 3 1B has 1B parameters. Embedding Parameters: 302M Non-embedding Parameters: 698M. 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 1B?

Gemma 3 1B was published by Google DeepMind, based in United States of America, categorised as industry.

When was Gemma 3 1B released?

Gemma 3 1B was published in March 2025.

What is Gemma 3 1B used for?

Gemma 3 1B works in Language, and is recorded as handling language modeling/generation, Question answering, Translation, Chat, Quantitative reasoning, Code generation, Mathematical reasoning. These are the areas it was designed around; they describe intent rather than a hard boundary.

Where can I download Gemma 3 1B?

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.
