AI PC

In one line: An AI PC is a computer built to run AI models on its own hardware instead of sending the work to a cloud service.

What it actually is

The label is used for two quite different machines, and mixing them up is the most common buying mistake.

• The laptop meaning — a thin laptop or office PC with an NPU (neural processing unit), a small low-power chip for light AI features such as live captions, background blur and the built-in Windows AI tools. It will not run a serious AI model on its own.
• The workstation meaning — a desktop built around a powerful graphics card, so that large language models and image generators can run entirely on the machine. This is what a business needs for a private chatbot or document assistant, and it is what an AI PC builder puts together.

What makes a desktop an AI PC

• Graphics card memory (VRAM) — the first spec to check, because the AI model has to fit inside it. 12GB is the entry point, 16GB suits most small offices, and 24–32GB runs the strongest open models.
• Power supply and cooling — high-end graphics cards draw a lot of power and give off a lot of heat, so the power supply, case and fans have to be sized for them.
• System memory and storage — 32GB or more of RAM and a fast SSD, since AI models are large files that are loaded often.
• Software setup — graphics drivers and the tools that actually run the models. A good builder installs and tests these before handover.

Why it matters for a small business

An AI PC keeps customer data, contracts and internal documents on your own premises, which helps with PDPA-sensitive work, and it replaces monthly cloud fees with a one-off hardware cost. It only pays off with regular use. If your team uses AI occasionally, a cloud subscription is still cheaper and simpler.
