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.

Could derive this in terms of Whisper v1, which according to the paper was trained for 680k hours for between 2-3 epochs. Whisper v3 was trained on 5 million hours for 2 epochs, or ~5-7x as much data, and has the same architecture. We have an estimate of 4.65e22 for Whisper 1. Assume Whisper v1 was trained on 2.5 epochs, or 2.5*680k = 1.7M hours. Whisper v3 was trained on 10M hours. 10/1.7 * 4.65e22 ~= 2.7e23

Fastest

2,186 tok/s

Whisper v3 reaches a parameter count of 1.6B. 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 23.8 tokens per second.

The fastest we calculate for it is B200, generating roughly 2,186 tokens per second on the strength of a memory bandwidth of 8,000 GB/s.

About this model

Whisper v3 was published by OpenAI, in the country recorded as United States of America, during November 2023. The category the publisher falls under is industry.

It works in the domain of Speech, and is recorded as performing the task of speech recognition (ASR).

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

How fast it runs, and why

Across every card that can run it, the middle of the range sits at 61.4 tokens per second. Producing text faster than most people read it: 796 of them.

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.

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.

What went into building it

Training it took a computation budget of roughly 2.7 × 10²³ FLOP. That figure measures what producing the model cost, and has no bearing on how fast it answers.

Training consumed a corpus of around 80,000,000,000 tokens of text.

Step by step

How to choose a GPU for Whisper v3

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

    The table lists every card able to hold Whisper v3, needing around 2.4 GB at a compression of Q8_0. That figure, not the headline performance of a card, is what decides whether it runs.

  2. 02

    Match the context to your actual use

    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 Whisper v3.

  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

    Rank by throughput rather than spec sheet

    Ranking by tokens per second follows memory bandwidth rather than core counts, for Whisper v3. It will not match a gaming ordering, because generation is bound by memory bandwidth. The card topping the list is B200, at 2,186 tok/s.

  5. 05

    Look at the headroom, not just the fit

    Tight means it loads and works with no room to raise the context later, in the case of Whisper v3. 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

    Check the card from the other side

    Every card name links to its own page, which runs the same calculation across the whole model catalogue. A card is usually bought for more than one model, so it is worth a look before buying for Whisper v3.

Answers

Whisper v3 — common questions

01

Whisper v3— what is it used for?

It works in the domain of Speech, and is recorded as handling the task of speech recognition (ASR). These are the areas it was designed around; they describe intent rather than a hard boundary.

02

Whisper v3— 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.

03

Whisper v3— how much compute was used to train it?

Training consumed around 2.7 × 10²³ FLOP. 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.

04

Whisper v3— 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.

05

Whisper v3— 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.

06

Whisper v3— why does the quantisation differ between cards?

A larger card holds a more accurate copy. The number of compression levels used across the cards that run it: 1. Bigger cards get the more accurate version, and the quality floor above pins the comparison to one level.

07

Whisper v3— how accurate are these speed estimates?

They are calculated from specifications rather than measured, and each carries a range. One example: 1,312–3,498 tok/s on B200. The same model and card vary by thirty to fifty per cent depending on the inference software and its version.

08

Whisper v3— 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 2.4 GB, and produces roughly 23.8 tokens per second. The number of cards able to run it in total: 818.

09

Whisper v3— how fast is it on a GPU?

It depends on the card. The quickest we calculate is B200, at about 2,186 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: 796.

10

Whisper v3— how much VRAM does it need?

It needs about 2.4 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.

11

Whisper v3— 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 2.4 GB and generating roughly 407 tokens per second. The fit is comfortable.

12

Whisper v3— 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 2.4 GB and generating roughly 249 tokens per second. The fit is comfortable.

13

Whisper v3— 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 2.4 GB and generating roughly 309 tokens per second. The fit is comfortable.

14

Whisper v3— 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 2.4 GB and generating roughly 366 tokens per second. The fit is comfortable.

15

Whisper v3— 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.

16

Whisper v3— how many parameters does it have?

It has a parameter count of 1.6B. 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.

17

Whisper v3— who created it?

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

18

Whisper v3— when was it released?

It was published in November 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.
