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

What the numbers mean

What it takes to run this model

Minimum card

Tesla C1080

Memory needed

0.7 GB

Fastest

260,633 tok/s

LSTM (2018) reaches a parameter count of 13M. 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 smallest card that holds it is Tesla C1080, with a memory capacity of 4 GB, running it at a compression of Q8_0 and producing around 2,836 tokens per second.

The fastest we calculate for it is B200, generating roughly 260,633 tokens per second on the strength of a memory bandwidth of 8,000 GB/s.

Background

LSTM (2018) was published by Intel Labs,Carnegie Mellon University (CMU), in the country recorded as United States of America, during March 2018. The publishing organisation is categorised as industry,Academia.

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

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.

Reading the throughput figures

Half the cards that hold it manage more than 7,318.6 tokens per second. Clearing the ten tokens per second that roughly matches reading speed: 818 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.

Without the attention layout on record, the memory column is an approximation. It is close enough to choose hardware by, and least reliable at long context.

How it was trained

The training set ran to roughly 103,000,000 tokens of text.

Step by step

How to choose a GPU for LSTM (2018)

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 able to hold LSTM (2018), needing around 0.7 GB at a compression of Q8_0. No amount of processing power compensates for a card that cannot hold it.

  2. 02

    Set the context length you will work at

    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 LSTM (2018).

  3. 03

    Set a quality floor

    The quantisation column varies by card, because a bigger card holds a more accurate copy, 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

    Sort by speed

    The speed ordering is effectively an ordering by memory bandwidth, for LSTM (2018). It will not match a gaming ordering, because generation is bound by memory bandwidth. The card topping the list is B200, at 260,633 tok/s.

  5. 05

    Check the fit verdict before buying

    A tight fit runs, but leaves nothing spare for a longer conversation, in the case of LSTM (2018). 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

    See what else that card runs

    Following a card through to its own page shows every other model it can hold, which is the question that follows once you have settled on LSTM (2018).

Answers

LSTM (2018) — common questions

01

LSTM (2018)— 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 0.7 GB and generating roughly 29,725 tokens per second. The fit is comfortable.

02

LSTM (2018)— 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 0.7 GB and generating roughly 36,814 tokens per second. The fit is comfortable.

03

LSTM (2018)— 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 0.7 GB and generating roughly 43,656 tokens per second. The fit is comfortable.

04

LSTM (2018)— 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.

05

LSTM (2018)— how many parameters does it have?

It has a parameter count of 13M. 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.

06

LSTM (2018)— who created it?

It was published by Intel Labs,Carnegie Mellon University (CMU), based in United States of America, an organisation categorised as industry,Academia.

07

LSTM (2018)— when was it released?

It was published in March 2018. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

08

LSTM (2018)— what is it used for?

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

09

LSTM (2018)— where can I download it?

The weights are published, though we do not hold a repository link for it. This site calculates hardware requirements rather than hosting model files.

10

LSTM (2018)— can I run it 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 model is rarely worth using. Every figure here assumes the whole model is resident on the card.

11

LSTM (2018)— would two GPUs run it faster?

Capacity adds across cards; throughput does not. The number of cards already holding it on their own: 818. So a second card is rarely the answer here.

12

LSTM (2018)— why does the quantisation differ between cards?

Because capacity varies, so does how hard it has to be squeezed. The number of distinct levels in the table above: 1. Bigger cards get the more accurate version, and the quality floor above pins the comparison to one level.

13

LSTM (2018)— how accurate are these speed estimates?

They are calculated from specifications rather than measured, and each carries a range. One example: 156,380–417,014 tok/s on B200. The same model and card vary by thirty to fifty per cent depending on the inference software and its version.

14

LSTM (2018)— 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 0.7 GB, and produces roughly 2,836 tokens per second. The number of cards able to run it in total: 818.

15

LSTM (2018)— how fast is it on a GPU?

It depends on the card. The quickest we calculate is B200, at about 260,633 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: 818.

16

LSTM (2018)— how much VRAM does it need?

It needs about 0.7 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.

17

LSTM (2018)— 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 0.7 GB and generating roughly 48,543 tokens per second. The fit is comfortable.
