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.

With 47B parameters, Nemotron-H 47B lands in the range a serious desktop card can handle once the weights are compressed. 93 of the cards we track can run it.

The least hardware that works is a Radeon PRO V710. Its 28 GB is enough at Q3_K_M compression, giving roughly 9.6 tokens per second.

Top of the range is the B200, at roughly 72.1 tokens per second thanks to 8,000 GB/s of bandwidth.

About this model

Nemotron-H 47B was published by NVIDIA, in United States of America, in April 2025. It comes out of industry.

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

Its starting point was Nemotron-H 56B — most models at this scale are adapted from an existing base rather than built from nothing.

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.

How fast it runs, and why

The median result is around 18.2 tokens per second; 72 cards produce text faster than most people read it.

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.

Step by step

How to choose a GPU for Nemotron-H 47B

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

  1. 01

    Read the memory figure first

    Look at what Nemotron-H 47B actually needs — around 23.7 GB at Q3_K_M. No amount of processing power compensates for a card that cannot hold it.

  2. 02

    Set the context length you will work at

    Set the context to what you will actually use. The cache grows with the conversation, and it is the usual reason Nemotron-H 47B stops fitting a card that seemed fine.

  3. 03

    Choose how far you will compress it

    Compression is what makes Nemotron-H 47B 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.

  4. 04

    Compare tokens per second, not specifications

    The speed ordering for Nemotron-H 47B is effectively an ordering by memory bandwidth, which is why the B200 tops it at 72.1 tok/s.

  5. 05

    Look at the headroom, not just the fit

    A tight fit runs Nemotron-H 47B but leaves nothing spare for a longer conversation; comfortable has headroom. If you expect to grow the context, buy for comfortable.

  6. 06

    See what else that card runs

    Every card name links to its own page, which runs the same calculation across the whole model catalogue. Worth a look before buying for Nemotron-H 47B alone — a card is usually bought for more than one model.

Answers

Nemotron-H 47B — common questions

01

Would two GPUs run Nemotron-H 47B faster?

Two cards buy memory rather than speed. That matters for Nemotron-H 47B only if one card cannot hold it — 93 can, so a second adds little.

02

Why does the quantisation differ between cards for Nemotron-H 47B?

Because capacity varies, so does how hard Nemotron-H 47B has to be squeezed — 5 distinct levels appear in the table above. Set a minimum quality to compare at one.

03

How accurate are these Nemotron-H 47B speed estimates?

They are calculated from specifications rather than measured, and each carries a range — 43–115 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.

04

What GPU do I need to run Nemotron-H 47B?

The smallest card in our catalogue that holds Nemotron-H 47B is the Radeon PRO V710, with 28 GB of memory. It runs the model at Q3_K_M using about 23.7 GB, and produces roughly 9.6 tokens per second. 93 cards in total can run it.

05

How fast is Nemotron-H 47B on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 72.1 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 47B clear that.

06

How much VRAM does Nemotron-H 47B need?

About 23.7 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.

07

Is Nemotron-H 47B open source?

Its weights are published, so Nemotron-H 47B 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.

08

How many parameters does Nemotron-H 47B have?

Nemotron-H 47B has 47B parameters. "We use MiniPuzzle to distill Nemotron-H-56B-Base to Nemotron-H-47B-Base, using only 63 billion training tokens and FP8 training". 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.

09

Who created Nemotron-H 47B?

Nemotron-H 47B was published by NVIDIA, based in United States of America, categorised as industry.

10

When was Nemotron-H 47B released?

Nemotron-H 47B was published in April 2025.

11

What is Nemotron-H 47B used for?

Nemotron-H 47B works in Language, and is recorded as handling language modeling/generation, Question answering, Translation, Quantitative reasoning, Code generation, Neural Architecture Search - NAS. These are the areas it was designed around; they describe intent rather than a hard boundary.

12

Where can I download Nemotron-H 47B?

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.

13

Can I run Nemotron-H 47B if it does not fit in my GPU?

It can be split between the card and system memory, but Nemotron-H 47B generates painfully slowly that way — the nearest miss we calculate is short by 7.5 GB. Nothing on this page assumes offloading.
