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, Qwen3.5-27B lands in the range a serious desktop card can handle once the weights are compressed. 241 of the cards we track can run it.

The entry point is the Xeon Phi 7120P: 16 GB of memory, Q3_K_M compression, roughly 9.7 tokens per second.

The quickest result comes from a B200 at around 125 tokens per second — its 8,000 GB/s of bandwidth is what buys that.

What this model is

Qwen3.5-27B was published by Alibaba, in China, in February 2026. industry is the category the publisher falls under.

It works in Language, and is recorded as doing language modeling/generation.

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 Qwen organisation on Hugging Face.

What decides the speed

Half the cards that hold it manage more than 19.0 tokens per second, and 196 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.

Its internal architecture is not on file, so memory is approximated from the parameter count and marked accordingly. Expect the real figure to differ, more so at long context.

Step by step

How to choose a GPU for Qwen3.5-27B

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

  1. 01

    Read the memory figure first

    Look at what Qwen3.5-27B actually needs — around 13.9 GB at Q3_K_M. No amount of processing power compensates for a card that cannot hold it.

  2. 02

    Match the context to your actual use

    Longer conversations cost memory on top of what the weights need. Move the slider to your real working length before trusting any row for Qwen3.5-27B.

  3. 03

    Set a quality floor

    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 Qwen3.5-27B by squeezing it further than you would want.

  4. 04

    Rank by throughput rather than spec sheet

    Ranking by tokens per second for Qwen3.5-27B 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 Qwen3.5-27B 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

    Following a card through to its own page shows every other model it can hold, which is the question that follows once Qwen3.5-27B is settled.

Answers

Qwen3.5-27B — common questions

01

How many parameters does Qwen3.5-27B have?

Qwen3.5-27B has 27B 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.

02

Who created Qwen3.5-27B?

Qwen3.5-27B was published by Alibaba, based in China, categorised as industry.

03

When was Qwen3.5-27B released?

Qwen3.5-27B was published in February 2026.

04

What is Qwen3.5-27B used for?

Qwen3.5-27B works in Language, and is recorded as handling 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.

05

Where can I download Qwen3.5-27B?

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

06

Can I run Qwen3.5-27B 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 — the nearest miss we calculate is short by 6.2 GB. Our figures for Qwen3.5-27B assume it is fully resident.

07

Would two GPUs run Qwen3.5-27B faster?

Capacity adds across cards; throughput does not. Since 241 of the cards we track already hold Qwen3.5-27B on their own, a second card is rarely the answer here.

08

Why does the quantisation differ between cards for Qwen3.5-27B?

Because capacity varies, so does how hard Qwen3.5-27B has to be squeezed — 5 distinct levels appear in the table above. Set a minimum quality to compare at one.

09

How accurate are these Qwen3.5-27B speed estimates?

They are calculated from specifications rather than measured, and each carries a range — 75–201 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.

10

What GPU do I need to run Qwen3.5-27B?

The smallest card in our catalogue that holds Qwen3.5-27B is the Xeon Phi 7120P, with 16 GB of memory. It runs the model at Q3_K_M using about 13.9 GB, and produces roughly 9.7 tokens per second. 241 cards in total can run it.

11

How fast is Qwen3.5-27B 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 Qwen3.5-27B clear that.

12

How much VRAM does Qwen3.5-27B need?

About 13.9 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.

13

Can I run Qwen3.5-27B on a 16 GB GPU?

Yes. A Tesla V100 SXM2 16 GB with 16 GB runs it at Q3_K_M, using about 13.9 GB and generating roughly 47.8 tokens per second — a tight fit.

14

Can I run Qwen3.5-27B on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q5_K_M, using about 20.2 GB and generating roughly 37.5 tokens per second — a tight fit.

15

Is Qwen3.5-27B open source?

Its weights are published, so Qwen3.5-27B 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.
