AI PCs and tablets: what to compare
An AI PC combines a general-purpose computer with hardware and software for running supported AI tasks locally. Start with the job you need it to do: caption a conversation, improve a video call, search your files, or run a particular model. Then check which processor and application support that job. A chatbot shortcut alone tells you very little about what the computer can run on its own.
What the NPU changes
A neural processing unit, or NPU, is a processor designed for AI workloads. Microsoft's Copilot+ PC guidance describes a Windows 11 hardware class with an NPU capable of more than 40 trillion operations per second, usually written as TOPS. The software must support that NPU to use it. A model may instead run on the CPU or GPU, so the advertised TOPS figure alone cannot tell you how fast your chosen app will be.
Use the manufacturer's exact processor specification and the app's supported hardware list together. Microsoft's Copilot+ PC developer guide explains NPU support and lists examples from Surface, HP, Dell, Acer, Lenovo, Samsung and ASUS.
Two concrete form factors
Microsoft's May 2025 announcement provides a useful pair to compare. The Surface Laptop, 13-inch has a built-in keyboard and touchpad. The Surface Pro, 12-inch is a tablet with a kickstand and detachable keyboard support. Both announced models use a Snapdragon X Plus processor with a 45 TOPS NPU. These are specific examples of the hardware category, not performance tests or a ranking of current PCs.
For the laptop, check the ports and screen size against your everyday work. For the tablet, check the complete configuration, including the keyboard and pen you need, and how it will sit on your desk or lap. Read Microsoft's Surface Laptop and Surface Pro announcement for those exact models. Prices, bundles and availability need a fresh check in your market.
Separate local processing from connected services
Check each feature's requirements individually. An NPU gives supported software a place to run AI processing on the device; it does not make every assistant, account service or AI app work offline. Record whether your chosen feature needs an internet connection, a download, a signed-in account or a paid plan. Microsoft's Surface PC overview is a starting point for distinguishing Windows PCs and Copilot+ PCs.
Check what is saved on the computer
Local processing still needs a privacy check. For example, Microsoft's Recall documentation says saving snapshots is an opt-in choice. Those snapshots and their associated information are encrypted on the local drive, and users can pause saving, exclude supported apps or websites, and delete snapshots. Check supported browsers and the feature's system requirements before relying on a filter. Read the Recall controls and requirements for the details. Other apps have their own storage and cloud policies.
Choose a computer or a dedicated device
Write down the apps you already use, the AI task you want to add, and where it needs to work. Check app and accessory compatibility, memory, storage, processor support and any ongoing service cost before comparing headline AI specifications. If your main task is capturing meetings or handwritten notes, also explore recorders and productivity devices. For portable voice help or translation, explore wearable and pocket assistants. Their tasks and operating requirements differ from a full Windows computer.
