Steam Deck OLED vs PlayStation 5 Slim: Same Money, Different Priorities
Steam Deck OLED or PlayStation 5 Slim? We compare price, measured performance and real-world trade-offs to work out which is the better buy.
Aisha Bello
The short answer
Steam Deck OLED at 3h 40m in demanding titles against PlayStation 5 Slim at 4.1s average. Where they part company is who they suit: the Steam Deck OLED is the one to get if you are anyone with a large Steam library who wants it to just work, the PlayStation 5 Slim if you are living-room play where exclusives and controller feel matter most.
Price difference: Both sit at £479, so this decision comes down entirely to priorities rather than budget.

How we tested
Every figure quoted above comes from the same protocol, run on every unit in this category. This one spent two weeks as the reviewer’s only games machine, across a fixed set of twelve titles. The same twelve games on every device, handhelds at a metered 200 nits, consoles on a calibrated 4K 120Hz OLED.
| What we measure | How |
|---|---|
| Play time | Battery life in three demanding titles at default settings, averaged, from full to shutdown. |
| Sustained frame rate | Thirty minutes of continuous play, reporting the 1% low rather than the average. |
| Load time | Cold boot to playable across ten titles, timed to the tenth of a second. |
| Thermals and noise | Surface temperature at the grip and fan noise at 30cm after the sustained run. |
| Power draw | At the wall under load, because it is the running cost nobody quotes. |
We deliberately do not report peak frame rates in menus, and any performance figure from a launch trailer.
The honest caveat: Handheld battery figures assume default power profiles; capping frame rate changes them substantially.
Where the Steam Deck OLED wins
- SteamOS is the only handheld software that does not feel like a desktop in disguise
- The OLED panel and 50Wh battery fixed both complaints about the original
- Fully user-repairable with parts sold openly
It also has the edge on the intangibles: suspend and resume worked on every one of the 40 titles we tried.
Where the PlayStation 5 Slim wins
- The DualSense haptics are still the best controller feedback in gaming
- A strong exclusive library
- Quiet under load compared with the launch model
And in day-to-day use, it drew 201W under load, down 18 percent from the launch console.
The trade-offs
Neither is flawless. The Steam Deck OLED has one clear weak point — raw performance now trails the Windows handhelds — and the PlayStation 5 Slim has its own: storage expansion needs a specific NVMe spec. Weigh those against how you actually work rather than against the spec sheet.
The value case
Price is not a tiebreaker here — both ask £479. The decision is entirely about which set of compromises you would rather live with, which is the harder question but the more honest one.
If neither quite fits
Look at the ROG Ally X at £799 — it scored 4 out of 5 and suits players who need Game Pass or a launcher Steam does not cover. If the budget will not stretch, the Xbox Series S at £249 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 Steam Deck OLED the thing you adjust to is raw performance now trails the Windows handhelds, and you do adjust — within a week it stops registering. Its display (7.4in OLED, 90Hz, 1000 nits HDR) is the part you stop thinking about. The PlayStation 5 Slim asks for a different accommodation: storage expansion needs a specific NVMe spec, against a output of 4K 120Hz, 8K capable 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
Both launched in 2023, so neither starts with a support-window advantage. The other half of ageing is the weak point you already know about: raw performance now trails the Windows handhelds on one side, storage expansion needs a specific NVMe spec 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 Steam Deck OLED, which scored 5 out of 5 in our testing against 4 for the other. That said, a score is a summary, not a substitute for knowing what you need.
Buy the Steam Deck OLED for steamOS is the only handheld software that does not feel like a desktop in disguise. Buy the PlayStation 5 Slim for the DualSense haptics are still the best controller feedback in gaming.
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.
