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

1.2 GB

Fastest

7,701 tok/s

EMDR is small enough at 440M parameters that hardware is rarely the obstacle — 818 of the cards we track can run it, including cards several years old.

The least hardware that works is a Tesla C1080. Its 4 GB is enough at Q8_0 compression, giving roughly 83.8 tokens per second.

The quickest result comes from a B200 at around 7,701 tokens per second — its 8,000 GB/s of bandwidth is what buys that.

Where it came from

EMDR was published by Mila - Quebec AI (originally Montreal Institute for Learning Algorithms),McGill University,DeepMind, in Canada, in June 2021. The organisation is categorised as academia,Academia,Industry.

It works in Language, and is recorded as doing question answering.

Because its weights were released, nothing about running it depends on a provider staying available — it is yours once downloaded.

Understanding the speeds

The median result is around 216.2 tokens per second; 817 cards produce text faster than most people read it.

It is a dense model, so every parameter is read for every token produced. That makes speed track memory bandwidth almost exactly — a card with twice the bandwidth generates roughly twice as fast.

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.

Training and provenance

Producing it required around 1.9 × 10²¹ FLOP of arithmetic, on NVIDIA A100, which is a statement about the training budget rather than about inference.

The training set ran to roughly 171,600,000,000 tokens.

The reason it appears in this catalogue at all is sOTA improvement.

Step by step

How to choose a GPU for EMDR

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

  1. 01

    Read the memory figure first

    Look at what EMDR actually needs — around 1.2 GB at Q8_0. No amount of processing power compensates for a card that cannot hold it.

  2. 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 EMDR.

  3. 03

    Set a quality floor

    The quantisation column varies by card, because a bigger card holds a more accurate copy of EMDR — Q8_0 on the smallest card that fits. Set a floor to hold the comparison at one level.

  4. 04

    Sort by speed

    The speed ordering for EMDR is effectively an ordering by memory bandwidth, which is why the B200 tops it at 7,701 tok/s.

  5. 05

    Read the fit column last

    The fit column separates cards that just manage EMDR from those with room to spare. Buy for the second if the context might grow.

  6. 06

    See what else that card runs

    Every card name links to its own page, which runs the same calculation across the whole model catalogue. Worth a look before buying for EMDR alone — a card is usually bought for more than one model.

Answers

EMDR — common questions

01

How much VRAM does EMDR need?

About 1.2 GB at Q8_0 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.

02

Can I run EMDR on a 8 GB GPU?

Yes. A CMP 170HX 8 GB with 8 GB runs it at Q8_0, using about 1.2 GB and generating roughly 1,434 tokens per second — a comfortable fit.

03

Can I run EMDR on a 12 GB GPU?

Yes. A GeForce RTX 3080 Ti with 12 GB runs it at Q8_0, using about 1.2 GB and generating roughly 878 tokens per second — a comfortable fit.

04

Can I run EMDR on a 16 GB GPU?

Yes. A Tesla V100 SXM2 16 GB with 16 GB runs it at Q8_0, using about 1.2 GB and generating roughly 1,088 tokens per second — a comfortable fit.

05

Can I run EMDR on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q8_0, using about 1.2 GB and generating roughly 1,290 tokens per second — a comfortable fit.

06

Is EMDR open source?

Its weights are published, so EMDR 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.

07

How many parameters does EMDR have?

EMDR has 440M parameters. Table 2. 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.

08

Who created EMDR?

EMDR was published by Mila - Quebec AI (originally Montreal Institute for Learning Algorithms),McGill University,DeepMind, based in Canada, categorised as academia,Academia,Industry.

09

When was EMDR released?

EMDR was published in June 2021. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

10

What is EMDR used for?

EMDR works in Language, and is recorded as handling question answering. These are the areas it was designed around; they describe intent rather than a hard boundary.

11

Where can I download EMDR?

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

12

How much compute was used to train EMDR?

Around 1.9 × 10²¹ FLOP, on NVIDIA A100. 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.

13

Can I run EMDR if it does not fit in my GPU?

Only by offloading, which is usually a false economy: the part in system memory drags the whole thing down. Our figures for EMDR assume it is fully resident.

14

Would two GPUs run EMDR faster?

A second card roughly doubles the memory available but not the generation rate. With 818 cards already able to run EMDR alone, the case for pairing is weak.

15

Why does the quantisation differ between cards for EMDR?

Because capacity varies, so does how hard EMDR has to be squeezed — 1 distinct levels appear in the table above. Set a minimum quality to compare at one.

16

How accurate are these EMDR speed estimates?

They are calculated from specifications rather than measured, and each carries a range — 4,620–12,321 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.

17

What GPU do I need to run EMDR?

The smallest card in our catalogue that holds EMDR is the Tesla C1080, with 4 GB of memory. It runs the model at Q8_0 using about 1.2 GB, and produces roughly 83.8 tokens per second. 818 cards in total can run it.

18

How fast is EMDR on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 7,701 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 817 of the cards that can run EMDR clear that.
