"I need a powerful laptop" is the most common thing we hear from buyers. But after testing dozens of 2026 ultrabooks, we're convinced: unless you're doing 3D rendering or training ML models, a sub-3-pound ultrabook handles everything most people do.
The Test
We took three popular ultrabooks and ran them through "power user" workloads:
- ASUS Zenbook 14 OLED (2.6 lbs) — Intel Core Ultra
- Lenovo IdeaPad Slim 5 14 (3.1 lbs) — Ryzen 7
- Apple MacBook Air M3 (2.7 lbs) — Apple M3
Workload Results
| Task | ASUS | Lenovo | MacBook Air | |------|------|--------|-------------| | 30 Chrome tabs + Spotify + Slack | Smooth | Smooth | Smooth | | 4K video editing (30 min timeline) | Smooth | Slight lag | Smooth | | Lightroom (200 RAW photos) | 3 min export | 3.5 min | 2.5 min | | Zoom + screen share + notes | Smooth | Smooth | Smooth | | Code compilation (medium project) | 45 sec | 52 sec | 38 sec |
All three handled every workload we threw at them. The MacBook Air was fastest thanks to Apple Silicon, but the difference was seconds, not minutes.
When You Actually Need More Power
- 3D modeling/animation: Need a dedicated GPU
- Machine learning: Need VRAM
- Gaming: Need a dedicated GPU
- 8K video editing: Need more RAM and GPU acceleration
That's it. For everything else — and that includes "data science with Python," "running Docker containers," and "multiple IDE instances" — an ultrabook is enough.
