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

The ten fastest GPUs that run Whisper v3

Ranked by estimated tokens per second, newest card first where speeds tie. Because generation is bound by memory bandwidth, this ordering follows bandwidth rather than any gaming benchmark.

The smallest GPUs that still run Whisper v3

The cheapest route in, by memory capacity. A tight fit runs the model but leaves nothing spare for a longer conversation.

What the numbers mean

What you need to run it

Minimum card

Tesla C1080

Memory needed

2.4 GB

Fastest

2,186 tok/s

Whisper v3 is small enough at 1.6B 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 23.8 tokens per second.

A B200 is the fastest we calculate for it: about 2,186 tokens per second, from 8,000 GB/s of memory bandwidth.

About this model

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

It works in Speech, and is recorded as doing 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 is about 61.4 tokens per second, and 796 of them clear the ten tokens per second that roughly matches reading speed.

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 roughly 2.7 × 10²³ FLOP of computation — a measure of what producing the model cost, not of how fast it answers.

Around 80,000,000,000 tokens went into training it.

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.

01

Check what it needs before anything else

The table lists every card that can hold Whisper v3 — around 2.4 GB at Q8_0. That figure, not the card's headline performance, is what decides whether it runs.
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 Whisper v3 stops fitting a card that seemed fine.
03

Decide how much compression you will accept

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 Whisper v3 by squeezing it further than you would want.
04

Rank by throughput rather than spec sheet

Ranking by tokens per second for Whisper v3 follows memory bandwidth, not core counts, which is why the B200 tops it at 2,186 tok/s.
05

Look at the headroom, not just the fit

Tight means Whisper v3 loads and works, with no room to raise the context later. Comfortable means you can. The difference matters more than a few tokens per second.
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. Worth a look before buying for Whisper v3 alone — a card is usually bought for more than one model.

Answers

Whisper v3 — common questions

What is Whisper v3 used for?

Whisper v3 works in Speech, and is recorded as handling speech recognition (ASR). These are the areas it was designed around; they describe intent rather than a hard boundary.

Where can I download Whisper v3?

The weights for Whisper v3 are published, though we do not hold a repository link for it. This site calculates hardware requirements rather than hosting model files.

How much compute was used to train Whisper v3?

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.

Can I run Whisper v3 if it does not fit in my GPU?

It can be split between the card and system memory, but Whisper v3 generates painfully slowly that way. Nothing on this page assumes offloading.

Would two GPUs run Whisper v3 faster?

Capacity adds across cards; throughput does not. Since 818 of the cards we track already hold Whisper v3 on their own, a second card is rarely the answer here.

Why does the quantisation differ between cards for Whisper v3?

A larger card holds a more accurate copy. Across the cards that run Whisper v3, 1 compression levels are used; the floor control above pins it to one.

How accurate are these Whisper v3 speed estimates?

They are calculated from specifications rather than measured, and each carries a range — 1,312–3,498 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.

What GPU do I need to run Whisper v3?

The smallest card in our catalogue that holds Whisper v3 is the Tesla C1080, with 4 GB of memory. It runs the model at Q8_0 using about 2.4 GB, and produces roughly 23.8 tokens per second. 818 cards in total can run it.

How fast is Whisper v3 on a GPU?

It depends on the card. The quickest we calculate is a 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 796 of the cards that can run Whisper v3 clear that.

How much VRAM does Whisper v3 need?

About 2.4 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.

Can I run Whisper v3 on a 8 GB GPU?

Yes. A CMP 170HX 8 GB with 8 GB runs it at Q8_0, using about 2.4 GB and generating roughly 407 tokens per second — a comfortable fit.

Can I run Whisper v3 on a 12 GB GPU?

Yes. A GeForce RTX 3080 Ti with 12 GB runs it at Q8_0, using about 2.4 GB and generating roughly 249 tokens per second — a comfortable fit.

Can I run Whisper v3 on a 16 GB GPU?

Yes. A Tesla V100 SXM2 16 GB with 16 GB runs it at Q8_0, using about 2.4 GB and generating roughly 309 tokens per second — a comfortable fit.

Can I run Whisper v3 on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q8_0, using about 2.4 GB and generating roughly 366 tokens per second — a comfortable fit.

Is Whisper v3 open source?

Its weights are published, so Whisper v3 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.

How many parameters does Whisper v3 have?

Whisper v3 has 1.6B parameters. 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.

Who created Whisper v3?

Whisper v3 was published by OpenAI, based in United States of America, categorised as industry.

When was Whisper v3 released?

Whisper v3 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.
