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 that run Deephermes 3 Llama 3 8B Preview

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 Deephermes 3 Llama 3 8B Preview

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

Quadro 6000

Memory needed

5.1 GB

Fastest

424 tok/s

Deephermes 3 Llama 3 8B Preview is small enough at 8B parameters that hardware is rarely the obstacle — 582 of the cards we track can run it, including cards several years old.

At the low end, a Quadro 6000 handles it — 6 GB, at Q3_K_M, for about 17.4 tokens per second.

Top of the range is the B200, at roughly 424 tokens per second thanks to 8,000 GB/s of bandwidth.

Where it came from

Deephermes 3 Llama 3 8B Preview was published by Nous Research, in United States of America, in February 2025. industry is the category the publisher falls under.

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

Its starting point was Llama 3.1-8B — most models at this scale are adapted from an existing base rather than built from nothing.

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 NousResearch organisation on Hugging Face.

Understanding the speeds

Half the cards that hold it manage more than 23.8 tokens per second, and 551 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.

Because the architecture is recorded, the memory column is derived rather than estimated.

What went into building it

Around 1,500,000,000 tokens went into training it.

Step by step

How to choose a GPU for Deephermes 3 Llama 3 8B Preview

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

The table lists every card that can hold Deephermes 3 Llama 3 8B Preview — around 5.1 GB at Q3_K_M. That figure, not the card's headline performance, is what decides whether it runs.
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 Deephermes 3 Llama 3 8B Preview.
03

Set a quality floor

Each card runs the least-compressed copy it can hold — Q3_K_M on the smallest card that fits. Setting a floor drops the cards that only manage Deephermes 3 Llama 3 8B Preview by squeezing it further than you would want.
04

Rank by throughput rather than spec sheet

Ranking by tokens per second for Deephermes 3 Llama 3 8B Preview follows memory bandwidth, not core counts, which is why the B200 tops it at 424 tok/s.
05

Check the fit verdict before buying

Tight means Deephermes 3 Llama 3 8B Preview loads and works, with no room to raise the context later. Comfortable means you can. The difference matters more than a few tokens per second.
06

Open the card you have settled on

Following a card through to its own page shows every other model it can hold, which is the question that follows once Deephermes 3 Llama 3 8B Preview is settled.

Answers

Deephermes 3 Llama 3 8B Preview — common questions

How accurate are these Deephermes 3 Llama 3 8B Preview speed estimates?

They are calculated from specifications rather than measured, and each carries a range — 360–508 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 Deephermes 3 Llama 3 8B Preview?

The smallest card in our catalogue that holds Deephermes 3 Llama 3 8B Preview is the Quadro 6000, with 6 GB of memory. It runs the model at Q3_K_M using about 5.1 GB, and produces roughly 17.4 tokens per second. 582 cards in total can run it.

How fast is Deephermes 3 Llama 3 8B Preview on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 424 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 551 of the cards that can run Deephermes 3 Llama 3 8B Preview clear that.

How much VRAM does Deephermes 3 Llama 3 8B Preview need?

About 5.1 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.

Can I run Deephermes 3 Llama 3 8B Preview on a 8 GB GPU?

Yes. A CMP 170HX 8 GB with 8 GB runs it at Q5_K_M, using about 7.0 GB and generating roughly 141 tokens per second — a tight fit.

Can I run Deephermes 3 Llama 3 8B Preview on a 12 GB GPU?

Yes. A GeForce RTX 3080 Ti with 12 GB runs it at Q8_0, using about 9.8 GB and generating roughly 48.3 tokens per second — a tight fit.

Can I run Deephermes 3 Llama 3 8B Preview on a 16 GB GPU?

Yes. A Tesla V100 SXM2 16 GB with 16 GB runs it at Q8_0, using about 9.8 GB and generating roughly 59.8 tokens per second — a comfortable fit.

Can I run Deephermes 3 Llama 3 8B Preview on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q8_0, using about 9.8 GB and generating roughly 70.9 tokens per second — a comfortable fit.

Is Deephermes 3 Llama 3 8B Preview open source?

Its weights are published, so Deephermes 3 Llama 3 8B Preview 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 Deephermes 3 Llama 3 8B Preview have?

Deephermes 3 Llama 3 8B Preview has 8B parameters. 8B. 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 Deephermes 3 Llama 3 8B Preview?

Deephermes 3 Llama 3 8B Preview was published by Nous Research, based in United States of America, categorised as industry.

When was Deephermes 3 Llama 3 8B Preview released?

Deephermes 3 Llama 3 8B Preview was published in February 2025.

What is Deephermes 3 Llama 3 8B Preview used for?

Deephermes 3 Llama 3 8B Preview works in Language, and is recorded as handling mathematical reasoning, Quantitative reasoning, Language modeling/generation, Question answering. These are the areas it was designed around; they describe intent rather than a hard boundary.

Where can I download Deephermes 3 Llama 3 8B Preview?

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

Can I run Deephermes 3 Llama 3 8B Preview if it does not fit in my GPU?

It can be split between the card and system memory, but Deephermes 3 Llama 3 8B Preview generates painfully slowly that way — the nearest miss we calculate is short by 1.5 GB. Nothing on this page assumes offloading.

Would two GPUs run Deephermes 3 Llama 3 8B Preview faster?

Capacity adds across cards; throughput does not. Since 582 of the cards we track already hold Deephermes 3 Llama 3 8B Preview on their own, a second card is rarely the answer here.

Why does the quantisation differ between cards for Deephermes 3 Llama 3 8B Preview?

Because capacity varies, so does how hard Deephermes 3 Llama 3 8B Preview has to be squeezed — 4 distinct levels appear in the table above. Set a minimum quality to compare at one.
