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.

Hardware requirements in practice

Minimum card

Tesla C1080

Memory needed

Fastest

2,259 tok/s

Hymba reaches a parameter count of 1.5B. That is small enough that hardware is rarely the obstacle, including on cards several years old. The number of cards we track that can run it: 818.

The entry point is Tesla C1080, with a memory capacity of 4 GB, running it at a compression of Q8_0 and producing around 24.6 tokens per second.

The fastest we calculate for it is B200, generating roughly 2,259 tokens per second on the strength of a memory bandwidth of 8,000 GB/s.

Background

Hymba was published by NVIDIA, in the country recorded as United States of America, during November 2024. The publishing organisation is categorised as industry.

It works in the domain of Language, and is recorded as performing the task of language modeling/generation, Question answering.

The weights being open is what puts this page in the calculator rather than only in the catalogue: it is a model you can actually hold. On Hugging Face it is published under the organisation nvidia.

Reading the throughput figures

The median result is around 63.4 tokens per second. Exceeding reading speed outright: 796 of them.

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.

How it was trained

Training it took a computation budget of roughly 1.4 × 10²² FLOP, on hardware recorded as NVIDIA A100. That figure measures what producing the model cost, and has no bearing on how fast it answers.

It was trained on a corpus of about 1,500,000,000,000 tokens of text.

Step by step

How to choose a GPU for Hymba

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

  1. 01

    Start from the memory column

    Every card here has been checked against Hymba, needing around 2.3 GB at a compression of Q8_0. No amount of processing power compensates for a card that cannot hold it.

  2. 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, because at long context a card that handles short questions easily can be dropped by Hymba.

  3. 03

    Set a quality floor

    Each card runs the least-compressed copy it can hold, reaching a compression of Q8_0 on the smallest card that fits. Setting a minimum quality drops the cards that only manage it by squeezing further than you would want, and holds the comparison at one level.

  4. 04

    Rank by throughput rather than spec sheet

    The speed ordering is effectively an ordering by memory bandwidth, for Hymba. It will not match a gaming ordering, because generation is bound by memory bandwidth. The card topping the list is B200, at 2,259 tok/s.

  5. 05

    Read the fit column last

    A tight fit runs, but leaves nothing spare for a longer conversation, in the case of Hymba. Comfortable means you can grow the context later. That difference matters more than a few tokens per second, so buy for comfortable if you expect to.

  6. 06

    Check the card from the other side

    Every card name links to its own page, which runs the same calculation across the whole model catalogue. A card is usually bought for more than one model, so it is worth a look before buying for Hymba.

Answers

Hymba — common questions

01

Hymba— can I run it on a GPU holding 8 GB?

Yes. The card CMP 170HX 8 GB, holding 8 GB, runs it at a compression of Q8_0, using about 2.3 GB and generating roughly 421 tokens per second. The fit is comfortable.

02

Hymba— can I run it on a GPU holding 12 GB?

Yes. The card GeForce RTX 3080 Ti, holding 12 GB, runs it at a compression of Q8_0, using about 2.3 GB and generating roughly 258 tokens per second. The fit is comfortable.

03

Hymba— can I run it on a GPU holding 16 GB?

Yes. The card Tesla V100 SXM2 16 GB, holding 16 GB, runs it at a compression of Q8_0, using about 2.3 GB and generating roughly 319 tokens per second. The fit is comfortable.

04

Hymba— can I run it on a GPU holding 24 GB?

Yes. The card GeForce RTX 5090 D V2, holding 24 GB, runs it at a compression of Q8_0, using about 2.3 GB and generating roughly 378 tokens per second. The fit is comfortable.

05

Hymba— is it open source?

Its weights are published, so it 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.

06

Hymba— how many parameters does it have?

It has a parameter count of 1.5B. 1.5B. 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.

07

Hymba— who created it?

It was published by NVIDIA, based in United States of America, an organisation categorised as industry.

08

Hymba— when was it released?

It was published in November 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.

09

Hymba— what is it used for?

It works in the domain of Language, and is recorded as handling the task of language modeling/generation, Question answering. These are the areas it was designed around; they describe intent rather than a hard boundary.

10

Hymba— where can I download it?

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

11

Hymba— how much compute was used to train it?

Training consumed around 1.4 × 10²² FLOP, on hardware recorded as NVIDIA A100. 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.

12

Hymba— can I run it if it does not fit in my GPU?

Only by offloading, which is usually a false economy: the part held in system memory drags the whole thing down. Every figure here assumes the whole model is resident on the card.

13

Hymba— would two GPUs run it faster?

A second card roughly doubles the memory available but not the generation rate. The number already able to run it alone: 818. So a second card is rarely the answer here.

14

Hymba— why does the quantisation differ between cards?

Each card is shown running the least-compressed copy it can hold. The number of distinct compression levels across the cards that fit it: 1. Bigger cards get the more accurate version, and the quality floor above pins the comparison to one level.

15

Hymba— how accurate are these speed estimates?

These are estimates with real error bars, and any of them could reasonably land anywhere in its published range depending on which runtime you use. The fastest result here: 1,355–3,614 tok/s on B200. The same model and card vary by thirty to fifty per cent depending on the inference software and its version.

16

Hymba— what GPU do I need to run it?

The smallest card in our catalogue that holds it is Tesla C1080, with a memory capacity of 4 GB. It runs the model at a compression of Q8_0 using about 2.3 GB, and produces roughly 24.6 tokens per second. The number of cards able to run it in total: 818.

17

Hymba— how fast is it on a GPU?

It depends on the card. The quickest we calculate is B200, at about 2,259 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and the number of cards clearing that: 796.

18

Hymba— how much VRAM does it need?

It needs about 2.3 GB at a compression of Q8_0, 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.
