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.

What the numbers mean

Hardware requirements in practice

Minimum card

Tesla C1080

Memory needed

0.8 GB

Fastest

36,433 tok/s

AlphaFold 2 is small enough at 93M 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 396 tokens per second.

Top of the range is the B200, at roughly 36,433 tokens per second thanks to 8,000 GB/s of bandwidth.

Where it came from

AlphaFold 2 was published by DeepMind, in United Kingdom of Great Britain and Northern Ireland, in November 2020. The organisation is categorised as industry.

It works in Biology, and is recorded as doing protein folding prediction, Proteins.

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 1,023.0 tokens per second; 818 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.

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.

Training and provenance

Training it took roughly 3 × 10²¹ FLOP of computation, on Google TPU v3 — a measure of what producing the model cost, not of how fast it answers.

The training set ran to roughly 5,724,000,000 tokens.

Its inclusion criterion is historical significance,Highly cited,SOTA improvement.

Step by step

How to choose a GPU for AlphaFold 2

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

  1. 01

    Start from the memory column

    The table lists every card that can hold AlphaFold 2 — around 0.8 GB at Q8_0. That figure, not the card's headline performance, is what decides whether it runs.

  2. 02

    Match the context to your actual use

    The conversation occupies memory too, and grows as it goes. Set the slider to the length you expect: at long context AlphaFold 2 can slip off a card that handles short questions easily.

  3. 03

    Decide how much compression you will accept

    The quantisation column varies by card, because a bigger card holds a more accurate copy of AlphaFold 2 — Q8_0 on the smallest card that fits. Set a floor to hold the comparison at one level.

  4. 04

    Rank by throughput rather than spec sheet

    Sort by speed to see how cards rank for AlphaFold 2. It will not match a gaming ordering — generation is bound by memory bandwidth, which is why the B200 tops it at 36,433 tok/s.

  5. 05

    Check the fit verdict before buying

    A tight fit runs AlphaFold 2 but leaves nothing spare for a longer conversation; comfortable has headroom. If you expect to grow the context, buy for comfortable.

  6. 06

    See what else that card runs

    Each card page repeats this sweep for every model we hold. It answers what else the hardware is good for, beyond AlphaFold 2.

Answers

AlphaFold 2 — common questions

01

Can I run AlphaFold 2 if it does not fit in my GPU?

Partly. Layers that do not fit sit in system memory and run at a fraction of the speed, so a mostly-offloaded AlphaFold 2 is rarely worth using. Every figure here assumes the whole model is on the card.

02

Would two GPUs run AlphaFold 2 faster?

A second card roughly doubles the memory available but not the generation rate. With 818 cards already able to run AlphaFold 2 alone, the case for pairing is weak.

03

Why does the quantisation differ between cards for AlphaFold 2?

Each card is shown running the least-compressed copy it can hold, and AlphaFold 2 appears at 1 different compression levels across the cards that fit it. Bigger cards get the more accurate version.

04

How accurate are these AlphaFold 2 speed estimates?

These are estimates with real error bars. The fastest result here, 21,860–58,292 tok/s on the B200, could reasonably land anywhere in its published range depending on which runtime you use.

05

What GPU do I need to run AlphaFold 2?

The smallest card in our catalogue that holds AlphaFold 2 is the Tesla C1080, with 4 GB of memory. It runs the model at Q8_0 using about 0.8 GB, and produces roughly 396 tokens per second. 818 cards in total can run it.

06

How fast is AlphaFold 2 on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 36,433 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 818 of the cards that can run AlphaFold 2 clear that.

07

How much VRAM does AlphaFold 2 need?

About 0.8 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.

08

Can I run AlphaFold 2 on a 8 GB GPU?

Yes. A CMP 170HX 8 GB with 8 GB runs it at Q8_0, using about 0.8 GB and generating roughly 6,786 tokens per second — a comfortable fit.

09

Can I run AlphaFold 2 on a 12 GB GPU?

Yes. A GeForce RTX 3080 Ti with 12 GB runs it at Q8_0, using about 0.8 GB and generating roughly 4,155 tokens per second — a comfortable fit.

10

Can I run AlphaFold 2 on a 16 GB GPU?

Yes. A Tesla V100 SXM2 16 GB with 16 GB runs it at Q8_0, using about 0.8 GB and generating roughly 5,146 tokens per second — a comfortable fit.

11

Can I run AlphaFold 2 on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q8_0, using about 0.8 GB and generating roughly 6,102 tokens per second — a comfortable fit.

12

Is AlphaFold 2 open source?

Its weights are published, so AlphaFold 2 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.

13

How many parameters does AlphaFold 2 have?

AlphaFold 2 has 93M parameters. https://arxiv.org/abs/2207.05477 reimplements AlphaFold 2 in a more efficient way, and states there are 93M parameters in the original version (Table 1). 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.

14

Who created AlphaFold 2?

AlphaFold 2 was published by DeepMind, based in United Kingdom of Great Britain and Northern Ireland, categorised as industry.

15

When was AlphaFold 2 released?

AlphaFold 2 was published in November 2020. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

16

What is AlphaFold 2 used for?

AlphaFold 2 works in Biology, and is recorded as handling protein folding prediction, Proteins. A model can carry several of each, so these are the areas it was built for rather than a limit on what it will attempt.

17

Where can I download AlphaFold 2?

The weights for AlphaFold 2 are published, though we do not hold a repository link for it. This site calculates hardware requirements rather than hosting model files.

18

How much compute was used to train AlphaFold 2?

Around 3 × 10²¹ FLOP, on Google TPU v3. 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.
