The “AI PC” Category (Important in 2025–2026)

AI PCs are becoming a new, clear category of computers, not just a marketing label. From 2025 onward, many buyers will actively choose between a regular laptop, an AI PC, or a workstation, depending on how much on-device AI work they expect to do.

4.1 What an AI PC Is (in Plain Words)

An AI PC is a computer designed to run AI tasks directly on the device, instead of sending everything to the cloud.

The key difference is the presence of a dedicated NPU (Neural Processing Unit) alongside the CPU and GPU.

The idea of CPU + GPU + NPU

• CPU → general tasks (apps, system operations)
  
• GPU → graphics and parallel workloads
  
• NPU → AI-specific tasks (very power-efficient)
  

This allows the computer to handle AI features locally, without constant internet use.

Examples of on-device AI tasks

• Real-time transcription
  
• Image and video enhancement
  
• Background removal and blur
  
• AI-powered search inside files
  
• Text rewriting and summarization
  
• Voice commands processed locally
  

Why AI PCs matter

Speed

• Storage
  
• Settings
  

Even though it is not a physical device, a VM can:

• Install software
  
• Run programs
  
• Store files
  
• Be restarted or copied easily
  

Simple example

• Your laptop opens a remote desktop
  
• You log in
  
• You are working on a computer that actually runs in a data center
  

Cloud Desktop / Virtual Desktop (VDI) Basics

A cloud desktop or Virtual Desktop Infrastructure (VDI) provides a full desktop experience over the internet.

Instead of buying a high-powered PC:

• The computer runs on cloud servers
  
• You access it using a browser or remote app
  
• Your device becomes just a screen, keyboard, and mouse
  

How cloud desktops work (step-by-step)

1. User logs in from a laptop, tablet, or thin client
   
2. A virtual desktop starts in the cloud
   
3. Apps and files load from the cloud system
