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 Llama 3.2 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 Llama 3.2 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 you need to run it

Minimum card

Tesla C1080

Memory needed

2.2 GB

Fastest

2,755 tok/s

Llama 3.2 1B is small enough at 1.2B parameters that hardware is rarely the obstacle — 818 of the cards we track can run it, including cards several years old.

The least hardware that works is a Tesla C1080. Its 4 GB is enough at Q8_0 compression, giving roughly 30.0 tokens per second.

At the other end, a B200 generates roughly 2,755 tokens per second on it, on the strength of 8,000 GB/s of memory bandwidth.

Where it came from

Llama 3.2 1B was published by Meta AI, in United States of America, in September 2024. It comes out of industry.

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

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.

Understanding the speeds

Half the cards that hold it manage more than 77.4 tokens per second, and 799 exceed reading speed outright.

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.

Training and provenance

Training it took roughly 6.6 × 10²² FLOP of computation, on NVIDIA H100 SXM5 80GB — a measure of what producing the model cost, not of how fast it answers.

It was trained on about 9,000,000,000,000 tokens of text.

Step by step

How to choose a GPU for Llama 3.2 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

Look at what Llama 3.2 1B actually needs — around 2.2 GB at Q8_0. No amount of processing power compensates for a card that cannot hold it.
02

Match the context to your actual use

The conversation occupies memory too, and grows as it goes. Set the slider to the length you expect: at long context Llama 3.2 1B can slip off a card that handles short questions easily.
03

Set a quality floor

Compression is what makes Llama 3.2 1B fit smaller cards, at some cost in accuracy — Q8_0 on the smallest card that fits. A minimum quality removes the ones that go too far.
04

Rank by throughput rather than spec sheet

Sort by speed to see how cards rank for Llama 3.2 1B. It will not match a gaming ordering — generation is bound by memory bandwidth, which is why the B200 tops it at 2,755 tok/s.
05

Check the fit verdict before buying

A tight fit runs Llama 3.2 1B but leaves nothing spare for a longer conversation; comfortable has headroom. If you expect to grow the context, buy for comfortable.
06

Open the card you have settled on

Following a card through to its own page shows every other model it can hold, which is the question that follows once Llama 3.2 1B is settled.

Answers

Llama 3.2 1B — common questions

Who created Llama 3.2 1B?

Llama 3.2 1B was published by Meta AI, based in United States of America, categorised as industry.

When was Llama 3.2 1B released?

Llama 3.2 1B was published in September 2024. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

What is Llama 3.2 1B used for?

Llama 3.2 1B works in Language, and is recorded as handling language modeling/generation, Text summarization, Question answering, Quantitative reasoning, Translation. 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 Llama 3.2 1B?

The weights for Llama 3.2 1B are published, though we do not hold a repository link for it. This site calculates hardware requirements rather than hosting model files.

How much compute was used to train Llama 3.2 1B?

Around 6.6 × 10²² FLOP, on NVIDIA H100 SXM5 80GB. 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 Llama 3.2 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 Llama 3.2 1B assume it is fully resident.

Would two GPUs run Llama 3.2 1B faster?

Capacity adds across cards; throughput does not. Since 818 of the cards we track already hold Llama 3.2 1B on their own, a second card is rarely the answer here.

Why does the quantisation differ between cards for Llama 3.2 1B?

Because capacity varies, so does how hard Llama 3.2 1B has to be squeezed — 1 distinct levels appear in the table above. Set a minimum quality to compare at one.

How accurate are these Llama 3.2 1B 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 2,341–3,306 tok/s on the B200 rather than a single number.

What GPU do I need to run Llama 3.2 1B?

The smallest card in our catalogue that holds Llama 3.2 1B is the Tesla C1080, with 4 GB of memory. It runs the model at Q8_0 using about 2.2 GB, and produces roughly 30.0 tokens per second. 818 cards in total can run it.

How fast is Llama 3.2 1B on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 2,755 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 799 of the cards that can run Llama 3.2 1B clear that.

How much VRAM does Llama 3.2 1B need?

About 2.2 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 Llama 3.2 1B on a 8 GB GPU?

Yes. A CMP 170HX 8 GB with 8 GB runs it at Q8_0, using about 2.2 GB and generating roughly 513 tokens per second — a comfortable fit.

Can I run Llama 3.2 1B on a 12 GB GPU?

Yes. A GeForce RTX 3080 Ti with 12 GB runs it at Q8_0, using about 2.2 GB and generating roughly 314 tokens per second — a comfortable fit.

Can I run Llama 3.2 1B on a 16 GB GPU?

Yes. A Tesla V100 SXM2 16 GB with 16 GB runs it at Q8_0, using about 2.2 GB and generating roughly 389 tokens per second — a comfortable fit.

Can I run Llama 3.2 1B on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q8_0, using about 2.2 GB and generating roughly 461 tokens per second — a comfortable fit.

Is Llama 3.2 1B open source?

Its weights are published, so Llama 3.2 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 Llama 3.2 1B have?

Llama 3.2 1B has 1.2B parameters. https://huggingface.co/meta-llama/Llama-3.2-1B. 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.
