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.

Athene-70B sits at 70B parameters, which puts it above consumer hardware and into the range where a card is bought for this purpose rather than repurposed for it. 61 of the cards we track can hold it.

The smallest card that holds it is the A100 PCIe 40 GB with 40 GB, running it at Q3_K_M and producing around 25.5 tokens per second.

Top of the range is the B200, at roughly 48.4 tokens per second thanks to 8,000 GB/s of bandwidth.

Background

Athene-70B was published by Nexusflow, in United States of America, in July 2024. It comes out of industry.

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

It is derived from Llama 3-70B rather than trained from scratch, which is the usual way a specialised model is produced.

Because its weights were released, nothing about running it depends on a provider staying available — it is yours once downloaded. It is published under the Nexusflow organisation on Hugging Face.

Reading the throughput figures

The median result is around 17.1 tokens per second; 50 cards produce text faster than most people read it.

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

Its internal architecture is not on file, so memory is approximated from the parameter count and marked accordingly. Expect the real figure to differ, more so at long context.

Step by step

How to choose a GPU for Athene-70B

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

    The table lists every card that can hold Athene-70B — around 34.9 GB at Q3_K_M. That figure, not the card's headline performance, is what decides whether it runs.

  2. 02

    Decide how long your conversations run

    The conversation occupies memory too, and grows as it goes. Set the slider to the length you expect: at long context Athene-70B can slip off a card that handles short questions easily.

  3. 03

    Decide how much compression you will accept

    The quantisation column varies by card, because a bigger card holds a more accurate copy of Athene-70B — Q3_K_M on the smallest card that fits. Set a floor to hold the comparison at one level.

  4. 04

    Compare tokens per second, not specifications

    The speed ordering for Athene-70B is effectively an ordering by memory bandwidth, which is why the B200 tops it at 48.4 tok/s.

  5. 05

    Check the fit verdict before buying

    The fit column separates cards that just manage Athene-70B from those with room to spare. Buy for the second if the context might grow.

  6. 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 Athene-70B.

Answers

Athene-70B — common questions

01

How much VRAM does Athene-70B need?

About 34.9 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.

02

Is Athene-70B open source?

Its weights are published, so Athene-70B 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.

03

How many parameters does Athene-70B have?

Athene-70B has 70B parameters. 70B. 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.

04

Who created Athene-70B?

Athene-70B was published by Nexusflow, based in United States of America, categorised as industry.

05

When was Athene-70B released?

Athene-70B was published in July 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.

06

What is Athene-70B used for?

Athene-70B works in Language, and is recorded as handling language modeling/generation, Question answering. These are the areas it was designed around; they describe intent rather than a hard boundary.

07

Where can I download Athene-70B?

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

08

Can I run Athene-70B 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 Athene-70B is rarely worth using — the nearest miss we calculate is short by 14.2 GB. Every figure here assumes the whole model is on the card.

09

Would two GPUs run Athene-70B faster?

A second card roughly doubles the memory available but not the generation rate. With 61 cards already able to run Athene-70B alone, the case for pairing is weak.

10

Why does the quantisation differ between cards for Athene-70B?

Because capacity varies, so does how hard Athene-70B has to be squeezed — 5 distinct levels appear in the table above. Set a minimum quality to compare at one.

11

How accurate are these Athene-70B speed estimates?

They are calculated from specifications rather than measured, and each carries a range — 29–77 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.

12

What GPU do I need to run Athene-70B?

The smallest card in our catalogue that holds Athene-70B is the A100 PCIe 40 GB, with 40 GB of memory. It runs the model at Q3_K_M using about 34.9 GB, and produces roughly 25.5 tokens per second. 61 cards in total can run it.

13

How fast is Athene-70B on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 48.4 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 50 of the cards that can run Athene-70B clear that.
