Laptop vs Desktop PC

Which one fits your workflow? A quick side-by-side of the trade-offs so you can choose with confidence.

Criterion

Laptop

Desktop PC

Portability
All-in-one, battery-powered, fits in a bag.
Stationary — tied to a desk and a wall outlet.
Raw performance
Limited by thermals and battery — mobile CPU/GPU variants.
Full-power desktop CPU/GPU with much better cooling.
Upgradeability
Mostly RAM and SSD — CPU and GPU are soldered.
Every component can be swapped or upgraded later.
Price / performance
Pay a premium for miniaturisation and battery.
More performance per dollar at every budget.
Display & peripherals
Built-in 13–17" screen, keyboard and trackpad.
Choose your own monitor(s), keyboard, mouse and audio.
Power draw
30–200 W — light on the electricity bill.
300–1000 W under load — needs a solid PSU.
Repair & lifespan
Harder to service; typical life 3–5 years.
Easy to repair part-by-part; 7–10+ years is normal.
Best for
Students, remote work, travel and note-taking.
Gaming, 3D, AI training, servers and heavy multitasking.
