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 Cambrian-1-34B

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 Cambrian-1-34B

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

RTX A4500

Memory needed

17.3 GB

Fastest

99.7 tok/s

With 34B parameters, Cambrian-1-34B lands in the range a serious desktop card can handle once the weights are compressed. 132 of the cards we track can run it.

The smallest card that holds it is the RTX A4500 with 20 GB, running it at Q3_K_M and producing around 21.5 tokens per second.

At the other end, a B200 generates roughly 99.7 tokens per second on it, on the strength of 8,000 GB/s of memory bandwidth.

About this model

Cambrian-1-34B was published by New York University (NYU), in United States of America, in June 2024. The organisation is categorised as academia.

It works in Multimodal, Vision, Language, and is recorded as doing image captioning, Visual question answering, Character recognition (OCR).

It builds on Yi-34B, 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 nyu-visionx organisation on Hugging Face.

How fast it runs, and why

Across every card that can run it, the middle of the range is about 21.2 tokens per second, and 103 of them clear the ten tokens per second that roughly matches reading speed.

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.

Memory here is estimated from size rather than computed from the architecture, which is not recorded for this model — the numbers are indicative rather than exact.

What went into building it

Its inclusion criterion is sOTA improvement.

Step by step

How to choose a GPU for Cambrian-1-34B

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

Every card here has been checked against Cambrian-1-34B — around 17.3 GB at Q3_K_M. Capacity is the gate — a card either holds it or it does not.
02

Match the context to your actual use

Longer conversations cost memory on top of what the weights need. Move the slider to your real working length before trusting any row for Cambrian-1-34B.
03

Decide how much compression you will accept

Compression is what makes Cambrian-1-34B fit smaller cards, at some cost in accuracy — Q3_K_M on the smallest card that fits. A minimum quality removes the ones that go too far.
04

Compare tokens per second, not specifications

Ranking by tokens per second for Cambrian-1-34B follows memory bandwidth, not core counts, which is why the B200 tops it at 99.7 tok/s.
05

Read the fit column last

The fit column separates cards that just manage Cambrian-1-34B 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 Cambrian-1-34B.

Answers

Cambrian-1-34B — common questions

Is Cambrian-1-34B open source?

Its weights are published, so Cambrian-1-34B 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 Cambrian-1-34B have?

Cambrian-1-34B has 34B parameters. 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 Cambrian-1-34B?

Cambrian-1-34B was published by New York University (NYU), based in United States of America, categorised as academia.

When was Cambrian-1-34B released?

Cambrian-1-34B was published in June 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 Cambrian-1-34B used for?

Cambrian-1-34B works in Multimodal, Vision, Language, and is recorded as handling image captioning, Visual question answering, Character recognition (OCR). These are the areas it was designed around; they describe intent rather than a hard boundary.

Where can I download Cambrian-1-34B?

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

Can I run Cambrian-1-34B if it does not fit in my GPU?

It can be split between the card and system memory, but Cambrian-1-34B generates painfully slowly that way — the nearest miss we calculate is short by 6.9 GB. Nothing on this page assumes offloading.

Would two GPUs run Cambrian-1-34B faster?

Two cards buy memory rather than speed. That matters for Cambrian-1-34B only if one card cannot hold it — 132 can, so a second adds little.

Why does the quantisation differ between cards for Cambrian-1-34B?

Each card is shown running the least-compressed copy it can hold, and Cambrian-1-34B appears at 5 different compression levels across the cards that fit it. Bigger cards get the more accurate version.

How accurate are these Cambrian-1-34B speed estimates?

They are calculated from specifications rather than measured, and each carries a range — 60–159 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 Cambrian-1-34B?

The smallest card in our catalogue that holds Cambrian-1-34B is the RTX A4500, with 20 GB of memory. It runs the model at Q3_K_M using about 17.3 GB, and produces roughly 21.5 tokens per second. 132 cards in total can run it.

How fast is Cambrian-1-34B on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 99.7 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 103 of the cards that can run Cambrian-1-34B clear that.

How much VRAM does Cambrian-1-34B need?

About 17.3 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 Cambrian-1-34B on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q4_K_M, using about 21.3 GB and generating roughly 38.5 tokens per second — a tight fit.
