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 Nemotron-H 56B

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 Nemotron-H 56B

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

FirePro S9170

Memory needed

28.1 GB

Fastest

60.5 tok/s

With 56B parameters, Nemotron-H 56B lands in the range a serious desktop card can handle once the weights are compressed. 92 of the cards we track can run it.

At the low end, a FirePro S9170 handles it — 32 GB, at Q3_K_M, for about 5.1 tokens per second.

A B200 is the fastest we calculate for it: about 60.5 tokens per second, from 8,000 GB/s of memory bandwidth.

Background

Nemotron-H 56B was published by NVIDIA, in United States of America, in April 2025. The organisation is categorised as industry.

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

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 nvidia organisation on Hugging Face.

Reading the throughput figures

Half the cards that hold it manage more than 15.4 tokens per second, and 72 exceed reading speed outright.

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

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.

Training and provenance

Producing it required around 6.7 × 10²⁴ FLOP of arithmetic, on NVIDIA H100 SXM5 80GB, which is a statement about the training budget rather than about inference.

Step by step

How to choose a GPU for Nemotron-H 56B

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 Nemotron-H 56B actually needs — around 28.1 GB at Q3_K_M. No amount of processing power compensates for a card that cannot hold it.
02

Decide how long your conversations run

Longer conversations cost memory on top of what the weights need. Move the slider to your real working length before trusting any row for Nemotron-H 56B.
03

Choose how far you will compress it

Compression is what makes Nemotron-H 56B 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

Sort by speed to see how cards rank for Nemotron-H 56B. It will not match a gaming ordering — generation is bound by memory bandwidth, which is why the B200 tops it at 60.5 tok/s.
05

Look at the headroom, not just the fit

A tight fit runs Nemotron-H 56B 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

Each card page repeats this sweep for every model we hold. It answers what else the hardware is good for, beyond Nemotron-H 56B.

Answers

Nemotron-H 56B — common questions

Can I run Nemotron-H 56B if it does not fit in my GPU?

Partly. Layers that do not fit sit in system memory and run at a fraction of the speed, so a mostly-offloaded Nemotron-H 56B is rarely worth using — the nearest miss we calculate is short by 9.4 GB. Every figure here assumes the whole model is on the card.

Would two GPUs run Nemotron-H 56B faster?

Two cards buy memory rather than speed. That matters for Nemotron-H 56B only if one card cannot hold it — 92 can, so a second adds little.

Why does the quantisation differ between cards for Nemotron-H 56B?

Because capacity varies, so does how hard Nemotron-H 56B has to be squeezed — 5 distinct levels appear in the table above. Set a minimum quality to compare at one.

How accurate are these Nemotron-H 56B 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 36–97 tok/s on the B200 rather than a single number.

What GPU do I need to run Nemotron-H 56B?

The smallest card in our catalogue that holds Nemotron-H 56B is the FirePro S9170, with 32 GB of memory. It runs the model at Q3_K_M using about 28.1 GB, and produces roughly 5.1 tokens per second. 92 cards in total can run it.

How fast is Nemotron-H 56B on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 60.5 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 72 of the cards that can run Nemotron-H 56B clear that.

How much VRAM does Nemotron-H 56B need?

About 28.1 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.

Is Nemotron-H 56B open source?

Its weights are published, so Nemotron-H 56B 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 Nemotron-H 56B have?

Nemotron-H 56B has 56B parameters. Model Architecture Architecture Type: Hybrid Mamba-Transformer Network Architecture: Nemotron-H This model has 56B model 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 Nemotron-H 56B?

Nemotron-H 56B was published by NVIDIA, based in United States of America, categorised as industry.

When was Nemotron-H 56B released?

Nemotron-H 56B was published in April 2025.

What is Nemotron-H 56B used for?

Nemotron-H 56B works in Language, and is recorded as handling language modeling/generation, Question answering, Translation, Quantitative reasoning, 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.

Where can I download Nemotron-H 56B?

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

How much compute was used to train Nemotron-H 56B?

Around 6.7 × 10²⁴ 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.
