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 Qwen2.5-Coder (1.5B)

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 Qwen2.5-Coder (1.5B)

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

2.3 GB

Fastest

2,200 tok/s

Qwen2.5-Coder (1.5B) is small enough at 1.5B 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 23.9 tokens per second.

At the other end, a B200 generates roughly 2,200 tokens per second on it, on the strength of 8,000 GB/s of memory bandwidth.

About this model

Qwen2.5-Coder (1.5B) was published by Alibaba, in China, in September 2024. It comes out of industry.

It works in Language, and is recorded as doing code generation, Code autocompletion, Quantitative reasoning, Question answering, 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.

How fast it runs, and why

Across every card that can run it, the middle of the range is about 61.8 tokens per second, and 796 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.

Without the attention layout on record, the memory column is an approximation. It is close enough to choose hardware by, and least reliable at long context.

Training and provenance

The training run consumed about 5.1 × 10²² FLOP. That figure describes the cost of creating it and has no bearing on how quickly it generates text.

Step by step

How to choose a GPU for Qwen2.5-Coder (1.5B)

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

Every card here has been checked against Qwen2.5-Coder (1.5B) — around 2.3 GB at Q8_0. Capacity is the gate — a card either holds it or it does not.
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 Qwen2.5-Coder (1.5B) can slip off a card that handles short questions easily.
03

Decide how much compression you will accept

The quantisation column varies by card, because a bigger card holds a more accurate copy of Qwen2.5-Coder (1.5B) — Q8_0 on the smallest card that fits. Set a floor to hold the comparison at one level.
04

Sort by speed

Sort by speed to see how cards rank for Qwen2.5-Coder (1.5B). It will not match a gaming ordering — generation is bound by memory bandwidth, which is why the B200 tops it at 2,200 tok/s.
05

Look at the headroom, not just the fit

A tight fit runs Qwen2.5-Coder (1.5B) but leaves nothing spare for a longer conversation; comfortable has headroom. If you expect to grow the context, buy for comfortable.
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 Qwen2.5-Coder (1.5B).

Answers

Qwen2.5-Coder (1.5B) — common questions

Can I run Qwen2.5-Coder (1.5B) on a 24 GB GPU?

Yes. A GeForce RTX 5090 D V2 with 24 GB runs it at Q8_0, using about 2.3 GB and generating roughly 369 tokens per second — a comfortable fit.

Is Qwen2.5-Coder (1.5B) open source?

Its weights are published, so Qwen2.5-Coder (1.5B) 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 Qwen2.5-Coder (1.5B) have?

Qwen2.5-Coder (1.5B) has 1.5B parameters. Number of Parameters: 1.54B. 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 Qwen2.5-Coder (1.5B)?

Qwen2.5-Coder (1.5B) was published by Alibaba, based in China, categorised as industry.

When was Qwen2.5-Coder (1.5B) released?

Qwen2.5-Coder (1.5B) was published in September 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.

What is Qwen2.5-Coder (1.5B) used for?

Qwen2.5-Coder (1.5B) works in Language, and is recorded as handling code generation, Code autocompletion, Quantitative reasoning, Question answering, 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.

Where can I download Qwen2.5-Coder (1.5B)?

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.

How much compute was used to train Qwen2.5-Coder (1.5B)?

Around 5.1 × 10²² 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 Qwen2.5-Coder (1.5B) 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 Qwen2.5-Coder (1.5B) is rarely worth using. Every figure here assumes the whole model is on the card.

Would two GPUs run Qwen2.5-Coder (1.5B) faster?

Two cards buy memory rather than speed. That matters for Qwen2.5-Coder (1.5B) only if one card cannot hold it — 818 can, so a second adds little.

Why does the quantisation differ between cards for Qwen2.5-Coder (1.5B)?

Each card is shown running the least-compressed copy it can hold, and Qwen2.5-Coder (1.5B) appears at 1 different compression levels across the cards that fit it. Bigger cards get the more accurate version.

How accurate are these Qwen2.5-Coder (1.5B) speed estimates?

These are estimates with real error bars. The fastest result here, 1,320–3,520 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 Qwen2.5-Coder (1.5B)?

The smallest card in our catalogue that holds Qwen2.5-Coder (1.5B) is the Tesla C1080, with 4 GB of memory. It runs the model at Q8_0 using about 2.3 GB, and produces roughly 23.9 tokens per second. 818 cards in total can run it.

How fast is Qwen2.5-Coder (1.5B) on a GPU?

It depends on the card. The quickest we calculate is a B200 at about 2,200 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 Qwen2.5-Coder (1.5B) clear that.

How much VRAM does Qwen2.5-Coder (1.5B) need?

About 2.3 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 Qwen2.5-Coder (1.5B) on a 8 GB GPU?

Yes. A CMP 170HX 8 GB with 8 GB runs it at Q8_0, using about 2.3 GB and generating roughly 410 tokens per second — a comfortable fit.

Can I run Qwen2.5-Coder (1.5B) on a 12 GB GPU?

Yes. A GeForce RTX 3080 Ti with 12 GB runs it at Q8_0, using about 2.3 GB and generating roughly 251 tokens per second — a comfortable fit.

Can I run Qwen2.5-Coder (1.5B) on a 16 GB GPU?

Yes. A Tesla V100 SXM2 16 GB with 16 GB runs it at Q8_0, using about 2.3 GB and generating roughly 311 tokens per second — a comfortable fit.
