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.

Hardware requirements in practice

Minimum card

Tesla C1080

Memory needed

1.3 GB

Fastest

6,072 tok/s

TrOCR is small enough at 558M parameters that hardware is rarely the obstacle — 818 of the cards we track can run it, including cards several years old.

The entry point is the Tesla C1080: 4 GB of memory, Q8_0 compression, roughly 66.1 tokens per second.

At the other end, a B200 generates roughly 6,072 tokens per second on it, on the strength of 8,000 GB/s of memory bandwidth.

Where it came from

TrOCR was published by Beihang University,Microsoft Research Asia, in China, in September 2021. It comes out of academia,Industry.

It works in Vision, and is recorded as doing character recognition (OCR).

The weights are published, so it can be downloaded and run on your own hardware indefinitely, offline, with no account attached.

Understanding the speeds

Half the cards that hold it manage more than 170.5 tokens per second, and 809 exceed reading speed outright.

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.

Memory here is estimated from size rather than computed from the architecture, which is not recorded for this model — the numbers are indicative rather than exact.

How it was trained

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

Step by step

How to choose a GPU for TrOCR

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

    Every card here has been checked against TrOCR — around 1.3 GB at Q8_0. Capacity is the gate — a card either holds it or it does not.

  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 TrOCR.

  3. 03

    Choose how far you will compress it

    Each card runs the least-compressed copy it can hold — Q8_0 on the smallest card that fits. Setting a floor drops the cards that only manage TrOCR by squeezing it further than you would want.

  4. 04

    Rank by throughput rather than spec sheet

    Ranking by tokens per second for TrOCR follows memory bandwidth, not core counts, which is why the B200 tops it at 6,072 tok/s.

  5. 05

    Check the fit verdict before buying

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

  6. 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 TrOCR.

Answers

TrOCR — common questions

01

How many parameters does TrOCR have?

TrOCR has 558M parameters. 558M table 5. 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.

02

Who created TrOCR?

TrOCR was published by Beihang University,Microsoft Research Asia, based in China, categorised as academia,Industry.

03

When was TrOCR released?

TrOCR was published in September 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.

04

What is TrOCR used for?

TrOCR works in Vision, and is recorded as handling character recognition (OCR). Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.

05

Where can I download TrOCR?

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

06

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

It can be split between the card and system memory, but TrOCR generates painfully slowly that way. Nothing on this page assumes offloading.

07

Would two GPUs run TrOCR faster?

Two cards buy memory rather than speed. That matters for TrOCR only if one card cannot hold it — 818 can, so a second adds little.

08

Why does the quantisation differ between cards for TrOCR?

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

09

How accurate are these TrOCR speed estimates?

These are estimates with real error bars. The fastest result here, 3,643–9,715 tok/s on the B200, could reasonably land anywhere in its published range depending on which runtime you use.

10

What GPU do I need to run TrOCR?

The smallest card in our catalogue that holds TrOCR is the Tesla C1080, with 4 GB of memory. It runs the model at Q8_0 using about 1.3 GB, and produces roughly 66.1 tokens per second. 818 cards in total can run it.

11

How fast is TrOCR on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 6,072 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 809 of the cards that can run TrOCR clear that.

12

How much VRAM does TrOCR need?

About 1.3 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.

13

Can I run TrOCR on a 8 GB GPU?

Yes. A CMP 170HX 8 GB with 8 GB runs it at Q8_0, using about 1.3 GB and generating roughly 1,131 tokens per second — a comfortable fit.

14

Can I run TrOCR on a 12 GB GPU?

Yes. A GeForce RTX 3080 Ti with 12 GB runs it at Q8_0, using about 1.3 GB and generating roughly 693 tokens per second — a comfortable fit.

15

Can I run TrOCR on a 16 GB GPU?

Yes. A Tesla V100 SXM2 16 GB with 16 GB runs it at Q8_0, using about 1.3 GB and generating roughly 858 tokens per second — a comfortable fit.

16

Can I run TrOCR on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q8_0, using about 1.3 GB and generating roughly 1,017 tokens per second — a comfortable fit.

17

Is TrOCR open source?

Its weights are published, so TrOCR 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.
