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.

Training compute

The arithmetic performed to train the model, measured in floating-point operations. It is a measure of what the training run cost, not of how fast the finished model answers you.

Training compute

"Pretraining utilized a cumulative 3.3M GPU hours of computation on hardware of type A100-80GB" of which 1720320 GPU hours were used to train the 70B model. 311.84 BF16 TFLOP/s * 1720320 hours * 0.40 utilization = 7.725e+23 FLOP. Alternatively: the model was trained for 1 epoch on 2 trillion tokens and has 70B parameters. C = 6ND = 6*70B*2T = 8.4e+23 FLOP.

Model was trained from January 2023 to July 2023, which is six months. However, the training run duration did not take up this whole period. According to a Meta employee interviewed by Epoch, Llama 2 34B and 70B were trained on different clusters, with overlapping training periods. Based on an estimate of 1000 GPUs, it would have taken 72 days.

48.4 tok/s

Llama 2-70B reaches a parameter count of 70B. That puts it above consumer hardware, into the range where a card is bought for this purpose rather than repurposed for it. The number of cards we track that can hold it: 61.

At the low end it is handled by A100 PCIe 40 GB, with a memory capacity of 40 GB, running it at a compression of IQ4_XS and producing around 23.2 tokens per second.

Top of the range is B200, generating roughly 48.4 tokens per second on the strength of a memory bandwidth of 8,000 GB/s.

Background

Llama 2-70B was published by Meta AI, in the country recorded as United States of America, during July 2023. The publishing organisation is categorised as industry.

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

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

Reading the throughput figures

Across every card that can run it, the middle of the range sits at 17.1 tokens per second. Exceeding reading speed outright: 49 of them.

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

Its attention layout is on file, so the memory figures are computed exactly rather than approximated.

What went into building it

Producing it required arithmetic totalling around 8.1 × 10²³ FLOP, on hardware recorded as NVIDIA A100 SXM4 80 GB. 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 2,000,000,000,000 tokens of text.

It is tracked in the underlying dataset for one reason in particular: historical significance,Significant use,Highly cited,Training cost.

Step by step

How to choose a GPU for Llama 2-70B

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

  1. 01

    Check what it needs before anything else

    Start from what it actually needs, which is the requirement of Llama 2-70B, needing around 35.8 GB at a compression of IQ4_XS. Capacity is the gate — a card either holds it or it does not.

  2. 02

    Decide how long your conversations run

    Set the context to what you will actually use. The cache grows with the conversation, and it is the usual reason a card that seemed fine stops fitting Llama 2-70B.

  3. 03

    Set a quality floor

    Compression is what makes a model fit smaller cards, at some cost in accuracy, reaching a compression of IQ4_XS 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

    Compare tokens per second, not specifications

    Ranking by tokens per second follows memory bandwidth rather than core counts, for Llama 2-70B. It will not match a gaming ordering, because generation is bound by memory bandwidth. The card topping the list is B200, at 48.4 tok/s.

  5. 05

    Look at the headroom, not just the fit

    The fit column separates cards that just manage it from those with room to spare, in the case of Llama 2-70B. 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

    Open the card you have settled on

    Each card page repeats this sweep for every model we hold, answering what else the hardware is good for beyond Llama 2-70B.

Answers

Llama 2-70B — common questions

01

Llama 2-70B— would two GPUs run it faster?

Capacity adds across cards; throughput does not. The number of cards already holding it on their own: 61. So a second card is rarely the answer here.

02

Llama 2-70B— 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: 4. Bigger cards get the more accurate version, and the quality floor above pins the comparison to one level.

03

Llama 2-70B— how accurate are these speed estimates?

They are calculated from specifications rather than measured, and each carries a range. One example: 41–58 tok/s on B200. The same model and card vary by thirty to fifty per cent depending on the inference software and its version.

04

Llama 2-70B— what GPU do I need to run it?

The smallest card in our catalogue that holds it is A100 PCIe 40 GB, with a memory capacity of 40 GB. It runs the model at a compression of IQ4_XS using about 35.8 GB, and produces roughly 23.2 tokens per second. The number of cards able to run it in total: 61.

05

Llama 2-70B— how fast is it on a GPU?

It depends on the card. The quickest we calculate is 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 the number of cards clearing that: 49.

06

Llama 2-70B— how much VRAM does it need?

It needs about 35.8 GB at a compression of IQ4_XS, 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

Llama 2-70B— 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.

08

Llama 2-70B— how many parameters does it have?

It has a parameter count of 70B. Llama has been released in 7B, 13B, 34B, and 70B variants. 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

Llama 2-70B— who created it?

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

10

Llama 2-70B— when was it released?

It was published in July 2023. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

11

Llama 2-70B— what is it used for?

It works in the domain of Language, and is recorded as handling the task of language modeling, Language modeling/generation, Question answering. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

12

Llama 2-70B— where can I download it?

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

13

Llama 2-70B— how much compute was used to train it?

Training consumed around 8.1 × 10²³ FLOP, on hardware recorded as NVIDIA A100 SXM4 80 GB. 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.

14

Llama 2-70B— 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. The nearest miss we calculate falls short by 11.1 GB. Every figure here assumes the whole model is resident on the card.
