Dell XPS 14 vs ASUS Zenbook 14 OLED: Is the 2025 Model Worth the Change?
Dell XPS 14 or ASUS Zenbook 14 OLED? We compare price, measured performance and real-world trade-offs to work out which is the better buy.

The short answer
Dell XPS 14 9h mixed use, ASUS Zenbook 14 OLED 12h 10m mixed use — the same test, run the same way. Where they part company is who they suit: the Dell XPS 14 is the one to get if you are buyers who prize industrial design over input ergonomics, the ASUS Zenbook 14 OLED if you are Windows users who want the MacBook Air experience.
Price difference: The ASUS Zenbook 14 OLED undercuts the Dell XPS 14 by £650. That gap only matters if the extras below are ones you will actually use.

How we tested
Every figure quoted above comes from the same protocol, run on every unit in this category. This one spent two working weeks as a primary machine, on battery wherever possible. Display at 150 nits, keyboard backlight off, the manufacturer’s balanced power profile, and the same browser profile with thirty tabs restored on every machine.
| What we measure | How |
|---|---|
| Battery life | A looped workday script — document editing, video calls, browsing — run to shutdown, three times, averaged. |
| Sustained CPU | A thirty-minute all-core render, reporting the settled clock speed rather than the boost figure. |
| Fan noise | Measured at 50cm from the display hinge during that render, in a room with a 28dB floor. |
| Chassis heat | Palm rest and underside temperatures after the render, since that is where it is actually felt. |
| Display | Brightness and contrast from a colorimeter, at the panel’s native setting rather than a boosted HDR mode. |
We deliberately do not report single-core burst scores, which almost nothing outside a benchmark actually produces.
The honest caveat: Sustained figures depend on ambient temperature. A warm room costs most thin laptops several percent.
Where the Dell XPS 14 wins
- A stunning OLED panel
- Genuinely premium construction
- Strong CPU performance
It also has the edge on the intangibles: the capacitive row cannot be used without looking at it.
Where the ASUS Zenbook 14 OLED wins
- A superb OLED panel for the money
- The best battery life of any Windows OLED machine we have tested
- A full port selection
And in day-to-day use, a 3K 120Hz OLED at this price undercuts everything comparable.
The trade-offs
Neither is flawless. The Dell XPS 14 has one clear weak point — a capacitive function row with no feedback — and the ASUS Zenbook 14 OLED has its own: a shallow keyboard. Weigh those against how you actually work rather than against the spec sheet.
The value case
The Dell XPS 14 costs £650 more and scores 1 point higher — roughly £650 per point of difference. Whether that is good value depends on whether the extra buys you a stunning OLED panel, or only a number. In our testing it is the former, but only just.
If neither quite fits
Look at the MacBook Air M4 at £1199 — it scored 5 out of 5 and suits students, writers and anyone who works away from a socket. If the budget will not stretch, the Acer Aspire 14 AI at £649 is the cheapest option in this category we would still put our name to.
Living with each of them
On paper the gap looks like a specification difference; in use it is a habits difference. With the Dell XPS 14 the thing you adjust to is a capacitive function row with no feedback, and you do adjust — within a week it stops registering. Its display (14.5in OLED, 3200 x 2000, 120Hz) is the part you stop thinking about. The ASUS Zenbook 14 OLED asks for a different accommodation: a shallow keyboard, against a display of 14in OLED, 2880 x 1800, 120Hz that holds up better than the number suggests. Neither compromise is severe. They are simply different, and which one you would rather not think about is a more useful question than which is objectively smaller.
Which one ages better
The ASUS Zenbook 14 OLED is 1 year newer, which usually means 1 more year of security updates at the far end of ownership — the part of the decision nobody weighs at the till and everybody feels at year four. The other half of ageing is the weak point you already know about: a shallow keyboard on one side, a capacitive function row with no feedback on the other. Weaknesses of that kind do not improve with firmware, so assume you are buying them for the life of the device and price the decision accordingly.
Our recommendation
For most people we would take the ASUS Zenbook 14 OLED, which scored 4 out of 5 in our testing against 3 for the other. That said, a score is a summary, not a substitute for knowing what you need.
Buy the Dell XPS 14 for a stunning OLED panel. Buy the ASUS Zenbook 14 OLED for a superb OLED panel for the money.
Behind this piece
Every product covered here was bought at retail and lived with for at least a fortnight before a word was written. Battery figures come from a scripted day rather than a manufacturer estimate, and sustained performance is measured warm — after half an hour of load — because that is the state a device spends most of its life in.
Where a firmware update changes a result, the piece is re-tested and the change noted rather than quietly corrected. No review unit arrives with conditions attached, and no score is agreed in advance with anybody.
