What is an AI PC? What the label means, and what it doesn't
Quick answer
An AI PC is a computer whose processor includes an NPU, a small chip for running AI features efficiently. Microsoft's stricter Copilot+ PC standard requires an NPU of more than 40 TOPS, 16 GB of RAM and 256 GB of storage, and unlocks extra Windows AI features. Neither label tells you whether a computer can run large AI models on its own; that depends mostly on how much fast memory it has.
“AI PC” is on almost every laptop sticker now, and it means less than it suggests. Here is what the label actually guarantees, and what to look at instead depending on what you want AI to do for you.
The short definition
An AI PC is a computer whose processor includes an NPU (neural processing unit): a small, power-efficient part of the chip designed for the math that AI features use. Intel, AMD, Qualcomm and Apple all build NPUs into their current laptop processors, so most new laptops, and many desktops, qualify.
A Copilot+ PC is Microsoft’s stricter standard. According to Microsoft, it needs:
- an NPU that can perform more than 40 trillion operations per second (40 TOPS),
- at least 16 GB of RAM and 256 GB of storage,
- Windows 11 version 24H2 or newer.
Microsoft lists AMD Ryzen AI 300-series, Intel Core Ultra 200V-series and Qualcomm Snapdragon X chips among those that qualify, and newer generations from all three do too. Many earlier “AI” processors from 2023 and 2024 have NPUs of roughly 10 to 16 TOPS and do not qualify.
What the NPU does for you
The NPU runs AI features that are always on or run often, without draining the battery the way the main processor or graphics chip would. On Copilot+ PCs, Windows uses it for features such as real-time translated captions and on-device image generation, and apps can use it through Windows’ AI programming interfaces.
For most people, that is the whole story of the “AI PC” label: some useful built-in features, and better battery life while using them.
What an AI PC does not tell you
Many people shopping for an “AI PC” actually want to run AI models themselves: chat assistants, coding helpers or document tools that work offline and privately. The label says almost nothing about that, for two reasons:
- Local AI apps mostly don’t use the NPU. Apps for running language models, such as LM Studio and the llama.cpp engine behind many of them, run models on the graphics processor or the main processor.
- Memory decides what runs, and how fast. A model has to fit in memory, and it writes about as fast as that memory can be read. In our 21-machine bandwidth study, writing speed tracked memory bandwidth almost perfectly; NPU TOPS don’t enter into it.
So a thin Copilot+ laptop with 16 GB of memory runs small models well, but an older desktop with a gaming graphics card can run the same models several times faster. On our own desktop, an 8 GB RTX 4060 wrote with Qwen3.5 9B at 45.5 tokens per second, against 10.4 on the processor alone.
Which kind of AI computer do you need?
| If you want… | Look for |
|---|---|
| Windows AI features, long battery life | Any Copilot+ PC; choose on screen, keyboard and battery like any laptop |
| To run small AI models (up to about 9B) | 16 GB of memory, or any graphics card with 8 GB |
| To run mid-size models (20B to 35B) | A 16 to 24 GB graphics card, or 32 GB or more of unified memory |
| To run the largest open models (70B to 120B) | 64 to 128 GB of unified memory: a Mac Studio, a Ryzen AI Max mini PC or a DGX Spark |

Questions people ask
Is a Copilot+ PC the same as an AI PC?
Every Copilot+ PC is an AI PC, but not the other way round. 'AI PC' is a loose industry term for any computer with an NPU, including 2023 and 2024 chips whose NPUs are too slow for Copilot+ features. Copilot+ is Microsoft's specific standard: an NPU of more than 40 TOPS, 16 GB of RAM, 256 GB of storage and Windows 11 version 24H2 or newer.
What does TOPS mean?
Trillions of operations per second: a measure of how much math an NPU can do, usually quoted for low-precision integer operations. It is useful for comparing NPUs with each other, but it says little about how fast a computer runs language models, which is limited mainly by memory bandwidth.
Can an AI PC run ChatGPT offline?
No: ChatGPT runs on OpenAI's servers. But many good open models, including OpenAI's own gpt-oss, run entirely on a local computer with apps such as LM Studio. How big a model and how fast depends on the computer's memory, not on whether it is sold as an AI PC.
Do local AI apps use the NPU?
Mostly not yet. Most apps for running language models locally use the graphics processor or the main processor. The NPU is used mainly by Windows features and apps written specifically for it.
