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 Qwen1.5-7B

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 Qwen1.5-7B

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

P102-101

Memory needed

8.5 GB

Fastest

484 tok/s

Qwen1.5-7B reaches a parameter count of 7B. That is small enough that hardware is rarely the obstacle, including on cards several years old. The number of cards we track that can run it: 306.

The smallest card that holds it is P102-101, with a memory capacity of 10 GB, running it at a compression of Q4_K_M and producing around 38.0 tokens per second.

The fastest we calculate for it is B200, generating roughly 484 tokens per second on the strength of a memory bandwidth of 8,000 GB/s.

About this model

Qwen1.5-7B was published by Alibaba, in the country recorded as China, during February 2024. It comes out of an organisation categorised as industry.

It works in the domain of Language, and is recorded as performing the task of chat, Language modeling/generation, Quantitative reasoning, Code generation, Translation.

Published weights mean the model runs on your machine rather than someone else's, which is what makes the hardware question below answerable at all. On Hugging Face it is published under the organisation Qwen.

How fast it runs, and why

Across every card that can run it, the middle of the range sits at 35.4 tokens per second. Producing text faster than most people read it: 289 of them.

Every weight participates in every token here, so bandwidth is the whole story: the ranking below is effectively a ranking of memory throughput.

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

What went into building it

The training run consumed about 1.7 × 10²³ FLOP. That figure measures what producing the model cost, and has no bearing on how fast it answers.

Step by step

How to choose a GPU for Qwen1.5-7B

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

The table lists every card able to hold Qwen1.5-7B, needing around 8.5 GB at a compression of Q4_K_M. Capacity is the gate — a card either holds it or it does not.
02

Decide how long your conversations run

Longer conversations cost memory on top of what the weights need. Move the slider to your real working length before trusting any row for Qwen1.5-7B.
03

Choose how far you will compress it

The quantisation column varies by card, because a bigger card holds a more accurate copy, reaching a compression of Q4_K_M on the smallest card that fits. Setting a minimum quality drops the cards that only manage it by squeezing further than you would want, and holds the comparison at one level.
04

Sort by speed

Sort by speed to see how cards rank for Qwen1.5-7B. It will not match a gaming ordering, because generation is bound by memory bandwidth. The card topping the list is B200, at 484 tok/s.
05

Check the fit verdict before buying

The fit column separates cards that just manage it from those with room to spare, in the case of Qwen1.5-7B. Comfortable means you can grow the context later. That difference matters more than a few tokens per second, so buy for comfortable if you expect to.
06

Check the card from the other side

Following a card through to its own page shows every other model it can hold, which is the question that follows once you have settled on Qwen1.5-7B.

Answers

Qwen1.5-7B — common questions

Qwen1.5-7B— is it open source?

Its weights are published, so it 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.

Qwen1.5-7B— how many parameters does it have?

It has a parameter count of 7B. 7B. 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.

Qwen1.5-7B— who created it?

It was published by Alibaba, based in China, an organisation categorised as industry.

Qwen1.5-7B— when was it released?

It 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.

Qwen1.5-7B— what is it used for?

It works in the domain of Language, and is recorded as handling the task of 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.

Qwen1.5-7B— where can I download it?

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

Qwen1.5-7B— how much compute was used to train it?

Training consumed around 1.7 × 10²³ 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.

Qwen1.5-7B— can I run it 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 model is rarely worth using. The nearest miss we calculate falls short by 1.3 GB. Every figure here assumes the whole model is resident on the card.

Qwen1.5-7B— would two GPUs run it faster?

A second card roughly doubles the memory available but not the generation rate. The number already able to run it alone: 306. So a second card is rarely the answer here.

Qwen1.5-7B— why does the quantisation differ between cards?

A larger card holds a more accurate copy. The number of compression levels used across the cards that run it: 4. Bigger cards get the more accurate version, and the quality floor above pins the comparison to one level.

Qwen1.5-7B— how accurate are these speed estimates?

They are calculated from specifications rather than measured, and each carries a range. One example: 411–581 tok/s on B200. The same model and card vary by thirty to fifty per cent depending on the inference software and its version.

Qwen1.5-7B— what GPU do I need to run it?

The smallest card in our catalogue that holds it is P102-101, with a memory capacity of 10 GB. It runs the model at a compression of Q4_K_M using about 8.5 GB, and produces roughly 38.0 tokens per second. The number of cards able to run it in total: 306.

Qwen1.5-7B— how fast is it on a GPU?

It depends on the card. The quickest we calculate is B200, at about 484 tokens per second; the slowest that still runs it manages considerably less. Reading speed is around ten tokens per second, and the number of cards clearing that: 289.

Qwen1.5-7B— how much VRAM does it need?

It needs about 8.5 GB at a compression of Q4_K_M, 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.

Qwen1.5-7B— can I run it on a GPU holding 12 GB?

Yes. The card GeForce RTX 3080 Ti, holding 12 GB, runs it at a compression of Q6_K, using about 10.1 GB and generating roughly 80.2 tokens per second. The fit is tight.

Qwen1.5-7B— can I run it on a GPU holding 16 GB?

Yes. The card Tesla V100 SXM2 16 GB, holding 16 GB, runs it at a compression of Q8_0, using about 11.8 GB and generating roughly 68.4 tokens per second. The fit is comfortable.

Qwen1.5-7B— can I run it on a GPU holding 24 GB?

Yes. The card GeForce RTX 5090 D V2, holding 24 GB, runs it at a compression of Q8_0, using about 11.8 GB and generating roughly 81.1 tokens per second. The fit is comfortable.
