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 Llama-3-70B-Synthia-v3.5

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 Llama-3-70B-Synthia-v3.5

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

What you need to run it

Minimum card

A100 PCIe 40 GB

Memory needed

33.0 GB

Fastest

48.4 tok/s

Llama-3-70B-Synthia-v3.5 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 least hardware that works is a A100 PCIe 40 GB. Its 40 GB is enough at Q3_K_M compression, giving roughly 25.5 tokens per second.

A B200 is the fastest we calculate for it: about 48.4 tokens per second, from 8,000 GB/s of memory bandwidth.

Background

Llama-3-70B-Synthia-v3.5 was published by its authors, in May 2024.

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

It builds on Llama 3-70B, which is why it shares that model's general shape and size.

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. It is published under the migtissera organisation on Hugging Face.

Reading the throughput figures

Half the cards that hold it manage more than 17.1 tokens per second, and 49 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.

Step by step

How to choose a GPU for Llama-3-70B-Synthia-v3.5

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

01

Start from the memory column

The table lists every card that can hold Llama-3-70B-Synthia-v3.5 — around 33.0 GB at Q3_K_M. That figure, not the card's headline performance, is what decides whether it runs.
02

Match the context to your actual use

Set the context to what you will actually use. The cache grows with the conversation, and it is the usual reason Llama-3-70B-Synthia-v3.5 stops fitting a card that seemed fine.
03

Set a quality floor

Compression is what makes Llama-3-70B-Synthia-v3.5 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 Llama-3-70B-Synthia-v3.5. It will not match a gaming ordering — generation is bound by memory bandwidth, which is why the B200 tops it at 48.4 tok/s.
05

Read the fit column last

The fit column separates cards that just manage Llama-3-70B-Synthia-v3.5 from those with room to spare. Buy for the second if the context might grow.
06

Check the card from the other side

Each card page repeats this sweep for every model we hold. It answers what else the hardware is good for, beyond Llama-3-70B-Synthia-v3.5.

Answers

Llama-3-70B-Synthia-v3.5 — common questions

How many parameters does Llama-3-70B-Synthia-v3.5 have?

Llama-3-70B-Synthia-v3.5 has 70B 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.

When was Llama-3-70B-Synthia-v3.5 released?

Llama-3-70B-Synthia-v3.5 was published in May 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.

What is Llama-3-70B-Synthia-v3.5 used for?

Llama-3-70B-Synthia-v3.5 works in Language, and is recorded as handling language modeling/generation, Question answering. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

Where can I download Llama-3-70B-Synthia-v3.5?

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

Can I run Llama-3-70B-Synthia-v3.5 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 Llama-3-70B-Synthia-v3.5 is rarely worth using — the nearest miss we calculate is short by 12.4 GB. Every figure here assumes the whole model is on the card.

Would two GPUs run Llama-3-70B-Synthia-v3.5 faster?

A second card roughly doubles the memory available but not the generation rate. With 61 cards already able to run Llama-3-70B-Synthia-v3.5 alone, the case for pairing is weak.

Why does the quantisation differ between cards for Llama-3-70B-Synthia-v3.5?

A larger card holds a more accurate copy. Across the cards that run Llama-3-70B-Synthia-v3.5, 4 compression levels are used; the floor control above pins it to one.

How accurate are these Llama-3-70B-Synthia-v3.5 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 41–58 tok/s on the B200 rather than a single number.

What GPU do I need to run Llama-3-70B-Synthia-v3.5?

The smallest card in our catalogue that holds Llama-3-70B-Synthia-v3.5 is the A100 PCIe 40 GB, with 40 GB of memory. It runs the model at Q3_K_M using about 33.0 GB, and produces roughly 25.5 tokens per second. 61 cards in total can run it.

How fast is Llama-3-70B-Synthia-v3.5 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 49 of the cards that can run Llama-3-70B-Synthia-v3.5 clear that.

How much VRAM does Llama-3-70B-Synthia-v3.5 need?

About 33.0 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 Llama-3-70B-Synthia-v3.5 open source?

Its weights are published, so Llama-3-70B-Synthia-v3.5 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.
