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.

On record

The arithmetic performed to train the model, measured in floating-point operations. It is a measure of what the training run cost, not of how fast the finished model answers you.

How it was established: Operation counting
Plausible range: 3.4 × 10²³ – 1.3 × 10²⁴ FLOP

Availability

Whether you can obtain the model and run it on your own hardware, which is what decides if any of the graphics-card figures on this page apply.

The extremes

The ten fastest GPUs that run Qwen1.5-32B

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 Qwen1.5-32B

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

The hardware side

Minimum card

RTX A4500

Memory needed

16.3 GB

Fastest

106 tok/s

With 32B parameters, Qwen1.5-32B lands in the range a serious desktop card can handle once the weights are compressed. 132 of the cards we track can run it.

At the low end, a RTX A4500 handles it — 20 GB, at Q3_K_M, for about 22.9 tokens per second.

The quickest result comes from a B200 at around 106 tokens per second — its 8,000 GB/s of bandwidth is what buys that.

Background

Qwen1.5-32B was published by Alibaba, in China, in February 2024. It comes out of industry.

It works in Language, and is recorded as doing chat, Language modeling/generation, Quantitative reasoning, Code generation, Translation.

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.

Reading the throughput figures

Half the cards that hold it manage more than 20.7 tokens per second, and 103 exceed reading speed outright.

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.

Its attention layout is on file, so the memory figures are computed exactly rather than approximated.

Step by step

How to choose a GPU for Qwen1.5-32B

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 Qwen1.5-32B actually needs — around 16.3 GB at Q3_K_M. No amount of processing power compensates for a card that cannot hold it.
02

Set the context length you will work at

Longer conversations cost memory on top of what the weights need. Move the slider to your real working length before trusting any row for Qwen1.5-32B.
03

Choose how far you will compress it

The quantisation column varies by card, because a bigger card holds a more accurate copy of Qwen1.5-32B — Q3_K_M on the smallest card that fits. Set a floor to hold the comparison at one level.
04

Compare tokens per second, not specifications

The speed ordering for Qwen1.5-32B is effectively an ordering by memory bandwidth, which is why the B200 tops it at 106 tok/s.
05

Read the fit column last

A tight fit runs Qwen1.5-32B but leaves nothing spare for a longer conversation; comfortable has headroom. If you expect to grow the context, buy for comfortable.
06

Each card page repeats this sweep for every model we hold. It answers what else the hardware is good for, beyond Qwen1.5-32B.

Answers

Qwen1.5-32B — common questions

What is Qwen1.5-32B used for?

Qwen1.5-32B works in Language, and is recorded as handling chat, Language modeling/generation, Quantitative reasoning, Code generation, Translation. These are the areas it was designed around; they describe intent rather than a hard boundary.

Where can I download Qwen1.5-32B?

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.

Can I run Qwen1.5-32B if it does not fit in my GPU?

It can be split between the card and system memory, but Qwen1.5-32B generates painfully slowly that way — the nearest miss we calculate is short by 5.7 GB. Nothing on this page assumes offloading.

Would two GPUs run Qwen1.5-32B faster?

Capacity adds across cards; throughput does not. Since 132 of the cards we track already hold Qwen1.5-32B on their own, a second card is rarely the answer here.

Why does the quantisation differ between cards for Qwen1.5-32B?

A larger card holds a more accurate copy. Across the cards that run Qwen1.5-32B, 5 compression levels are used; the floor control above pins it to one.

How accurate are these Qwen1.5-32B speed estimates?

They are calculated from specifications rather than measured, and each carries a range — 90–127 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 Qwen1.5-32B?

The smallest card in our catalogue that holds Qwen1.5-32B is the RTX A4500, with 20 GB of memory. It runs the model at Q3_K_M using about 16.3 GB, and produces roughly 22.9 tokens per second. 132 cards in total can run it.

How fast is Qwen1.5-32B on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 106 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and 103 of the cards that can run Qwen1.5-32B clear that.

How much VRAM does Qwen1.5-32B need?

About 16.3 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.

Can I run Qwen1.5-32B on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q4_K_M, using about 20.1 GB and generating roughly 40.9 tokens per second — a tight fit.

Is Qwen1.5-32B open source?

Its weights are published, so Qwen1.5-32B 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 Qwen1.5-32B have?

Qwen1.5-32B has 32B parameters. 32B. 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 Qwen1.5-32B?

Qwen1.5-32B was published by Alibaba, based in China, categorised as industry.

When was Qwen1.5-32B released?

Qwen1.5-32B was published in February 2024. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.
