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 v2

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 v2

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 it takes to run this model

Minimum card

Tesla C1080

Memory needed

2.4 GB

Fastest

2,186 tok/s

Whisper v2 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 smallest card that holds it is the Tesla C1080 with 4 GB, running it at Q8_0 and producing around 23.8 tokens per second.

At the other end, a B200 generates roughly 2,186 tokens per second on it, on the strength of 8,000 GB/s of memory bandwidth.

About this model

Whisper v2 was published by OpenAI, in United States of America, in December 2022. The organisation is categorised as industry.

It works in Speech, and is recorded as doing speech recognition (ASR).

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

How fast it runs, and why

Half the cards that hold it manage more than 61.4 tokens per second, and 796 exceed reading speed outright.

Every weight participates in every token here, so bandwidth is the whole story: the ranking below is effectively a ranking of memory throughput.

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.

What went into building it

Producing it required around 1.1 × 10²³ FLOP of arithmetic, which is a statement about the training budget rather than about inference.

Around 12,403,200,000 tokens went into training it.

Step by step

How to choose a GPU for Whisper v2

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

01

Start from the memory column

Look at what Whisper v2 actually needs — around 2.4 GB at Q8_0. No amount of processing power compensates for a card that cannot hold it.
02

Set the context length you will work at

Set the context to what you will actually use. The cache grows with the conversation, and it is the usual reason Whisper v2 stops fitting a card that seemed fine.
03

Set a quality floor

The quantisation column varies by card, because a bigger card holds a more accurate copy of Whisper v2 — Q8_0 on the smallest card that fits. Set a floor to hold the comparison at one level.
04

Compare tokens per second, not specifications

Ranking by tokens per second for Whisper v2 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

The fit column separates cards that just manage Whisper v2 from those with room to spare. Buy for the second if the context might grow.
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 Whisper v2 alone — a card is usually bought for more than one model.

Answers

Whisper v2 — common questions

Is Whisper v2 open source?

Its weights are published, so Whisper v2 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 v2 have?

Whisper v2 has 1.6B parameters. 1550M. 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 v2?

Whisper v2 was published by OpenAI, based in United States of America, categorised as industry.

When was Whisper v2 released?

Whisper v2 was published in December 2022. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

What is Whisper v2 used for?

Whisper v2 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 v2?

The weights for Whisper v2 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 v2?

Around 1.1 × 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 v2 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 Whisper v2 assume it is fully resident.

Would two GPUs run Whisper v2 faster?

A second card roughly doubles the memory available but not the generation rate. With 818 cards already able to run Whisper v2 alone, the case for pairing is weak.

Why does the quantisation differ between cards for Whisper v2?

Each card is shown running the least-compressed copy it can hold, and Whisper v2 appears at 1 different compression levels across the cards that fit it. Bigger cards get the more accurate version.

How accurate are these Whisper v2 speed estimates?

These are estimates with real error bars. The fastest result here, 1,312–3,498 tok/s on the B200, could reasonably land anywhere in its published range depending on which runtime you use.

What GPU do I need to run Whisper v2?

The smallest card in our catalogue that holds Whisper v2 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 v2 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 v2 clear that.

How much VRAM does Whisper v2 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 v2 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 v2 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 v2 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 v2 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.
