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 you need to run it

Minimum card

Tesla C1080

Memory needed

1.1 GB

Fastest

9,035 tok/s

SimCLR reaches a parameter count of 375M. 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 least hardware that works is Tesla C1080, with a memory capacity of 4 GB, running it at a compression of Q8_0 and producing around 98.3 tokens per second.

The fastest we calculate for it is B200, generating roughly 9,035 tokens per second on the strength of a memory bandwidth of 8,000 GB/s.

Where it came from

SimCLR was published by Google Brain, in the country recorded as United States of America, during February 2020. The publishing organisation is categorised as industry.

It works in the domain of Vision, and is recorded as performing the task of image completion.

Published weights mean the model runs on your machine rather than someone else's, which is what makes the hardware question below answerable at all.

Understanding the speeds

The median result is around 253.7 tokens per second. Producing text faster than most people read it: 817 of them.

Being dense, it reads all of itself per token, which is why the ordering by speed below follows the ordering by memory bandwidth so closely.

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.

What went into building it

Training consumed a corpus of around 10,467,704,832 tokens of text.

The reason it appears in this catalogue at all: highly cited.

Step by step

How to choose a GPU for SimCLR

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 SimCLR, needing around 1.1 GB at a compression of Q8_0. That figure, not the headline performance of a card, is what decides whether it runs.

  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 SimCLR.

  3. 03

    Decide how much compression you will accept

    Each card runs the least-compressed copy it can hold, 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

    Compare tokens per second, not specifications

    The speed ordering is effectively an ordering by memory bandwidth, for SimCLR. It will not match a gaming ordering, because generation is bound by memory bandwidth. The card topping the list is B200, at 9,035 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 SimCLR. 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 SimCLR.

Answers

SimCLR — common questions

01

SimCLR— 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.

02

SimCLR— 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.

03

SimCLR— how accurate are these speed estimates?

They are calculated from specifications rather than measured, and each carries a range. One example: 5,421–14,456 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

SimCLR— 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 1.1 GB, and produces roughly 98.3 tokens per second. The number of cards able to run it in total: 818.

05

SimCLR— how fast is it on a GPU?

It depends on the card. The quickest we calculate is B200, at about 9,035 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: 817.

06

SimCLR— how much VRAM does it need?

It needs about 1.1 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.

07

SimCLR— 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 1.1 GB and generating roughly 1,683 tokens per second. The fit is comfortable.

08

SimCLR— 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 1.1 GB and generating roughly 1,030 tokens per second. The fit is comfortable.

09

SimCLR— 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 1.1 GB and generating roughly 1,276 tokens per second. The fit is comfortable.

10

SimCLR— 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 1.1 GB and generating roughly 1,513 tokens per second. The fit is comfortable.

11

SimCLR— 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.

12

SimCLR— how many parameters does it have?

It has a parameter count of 375M. source: https://openai.com/blog/image-gpt/. 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.

13

SimCLR— who created it?

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

14

SimCLR— when was it released?

It was published in February 2020. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

15

SimCLR— what is it used for?

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

16

SimCLR— 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.

17

SimCLR— can I run it if it does not fit in my GPU?

It can be split between the card and system memory, but it generates painfully slowly that way. Every figure here assumes the whole model is resident on the card.
