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.

With 27B parameters, TxGemma 27B lands in the range a serious desktop card can handle once the weights are compressed. 241 of the cards we track can run it.

At the low end, a Xeon Phi 7120P handles it — 16 GB, at Q3_K_M, for about 9.7 tokens per second.

At the other end, a B200 generates roughly 125 tokens per second on it, on the strength of 8,000 GB/s of memory bandwidth.

Background

TxGemma 27B was published by Google DeepMind,Google Research, in United States of America, in April 2025. It comes out of industry,Industry.

It works in Language, Biology, and is recorded as doing protein or nucleotide language model (pLM/nLM), Protein property prediction, Small molecule property prediction, Chat, Question answering, Protein question answering, Protein function prediction, Language modeling/generation.

Its starting point was Gemma 2 27B — most models at this scale are adapted from an existing base rather than built from nothing.

The weights are published, so it can be downloaded and run on your own hardware indefinitely, offline, with no account attached. It is published under the google organisation on Hugging Face.

Reading the throughput figures

Across every card that can run it, the middle of the range is about 19.0 tokens per second, and 196 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.

Because the architecture is recorded, the memory column is derived rather than estimated.

How it was trained

Training it took roughly 2.1 × 10²⁴ FLOP of computation, on Google TPU v4 — a measure of what producing the model cost, not of how fast it answers.

Step by step

How to choose a GPU for TxGemma 27B

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

    Look at what TxGemma 27B actually needs — around 14.4 GB at Q3_K_M. No amount of processing power compensates for a card that cannot hold it.

  2. 02

    Decide how long your conversations run

    The conversation occupies memory too, and grows as it goes. Set the slider to the length you expect: at long context TxGemma 27B can slip off a card that handles short questions easily.

  3. 03

    Decide how much compression you will accept

    Each card runs the least-compressed copy it can hold — Q3_K_M on the smallest card that fits. Setting a floor drops the cards that only manage TxGemma 27B by squeezing it further than you would want.

  4. 04

    Compare tokens per second, not specifications

    Ranking by tokens per second for TxGemma 27B follows memory bandwidth, not core counts, which is why the B200 tops it at 125 tok/s.

  5. 05

    Look at the headroom, not just the fit

    A tight fit runs TxGemma 27B but leaves nothing spare for a longer conversation; comfortable has headroom. If you expect to grow the context, buy for comfortable.

  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 TxGemma 27B.

Answers

TxGemma 27B — common questions

01

What GPU do I need to run TxGemma 27B?

The smallest card in our catalogue that holds TxGemma 27B is the Xeon Phi 7120P, with 16 GB of memory. It runs the model at Q3_K_M using about 14.4 GB, and produces roughly 9.7 tokens per second. 241 cards in total can run it.

02

How fast is TxGemma 27B on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 125 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 196 of the cards that can run TxGemma 27B clear that.

03

How much VRAM does TxGemma 27B need?

About 14.4 GB at Q3_K_M 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.

04

Can I run TxGemma 27B on a 16 GB GPU?

Yes. A Tesla V100 SXM2 16 GB with 16 GB runs it at Q3_K_M, using about 14.4 GB and generating roughly 47.8 tokens per second — a tight fit.

05

Can I run TxGemma 27B on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q5_K_M, using about 20.6 GB and generating roughly 37.5 tokens per second — a tight fit.

06

Is TxGemma 27B open source?

Its weights are published, so TxGemma 27B 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.

07

How many parameters does TxGemma 27B have?

TxGemma 27B has 27B parameters. 27B. 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.

08

Who created TxGemma 27B?

TxGemma 27B was published by Google DeepMind,Google Research, based in United States of America, categorised as industry,Industry.

09

When was TxGemma 27B released?

TxGemma 27B was published in April 2025.

10

What is TxGemma 27B used for?

TxGemma 27B works in Language, Biology, and is recorded as handling protein or nucleotide language model (pLM/nLM), Protein property prediction, Small molecule property prediction, Chat, Question answering, Protein question answering, Protein function prediction, Language modeling/generation. 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.

11

Where can I download TxGemma 27B?

Its weights are published under the google organisation on Hugging Face. We do not host model files — this site calculates what hardware is needed to run them.

12

How much compute was used to train TxGemma 27B?

Around 2.1 × 10²⁴ FLOP, on Google TPU v4. 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.

13

Can I run TxGemma 27B 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 TxGemma 27B is rarely worth using — the nearest miss we calculate is short by 6.7 GB. Every figure here assumes the whole model is on the card.

14

Would two GPUs run TxGemma 27B faster?

Capacity adds across cards; throughput does not. Since 241 of the cards we track already hold TxGemma 27B on their own, a second card is rarely the answer here.

15

Why does the quantisation differ between cards for TxGemma 27B?

A larger card holds a more accurate copy. Across the cards that run TxGemma 27B, 5 compression levels are used; the floor control above pins it to one.

16

How accurate are these TxGemma 27B speed estimates?

They are calculated from specifications rather than measured, and each carries a range — 107–151 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.
