Aperçu
The 30-Second Version
The ASUS ExpertBook CX54 has one of the best screens we've seen on a Chromebook and a premium all-metal build. Performance is solid for ChromeOS but gaming is a lost cause. At the low end of its USD 238-800 price range, it's a steal. At the high end, think twice.
Pros & Cons
Points forts
- Gorgeous 14-inch 2K display with 120Hz and 500 nits, one of the best screens on any Chromebook 97th

- 16GB of RAM keeps ChromeOS buttery smooth even with dozens of tabs open 80th

Points faibles

Les preuves
Performance
The Core Ultra 5 Series 1 chip is a solid performer, but it lands in the 36th percentile for CPUs in our database. That's mediocre territory for a laptop at this tier. The 16GB of LPDDR5X RAM helps ChromeOS fly, and the 256GB SSD keeps things snappy, though that storage capacity is a weak spot at the 16th percentile. The integrated Intel Graphics are fine for everyday tasks and light photo editing, but gaming is a non-starter. Our gaming score for this thing is 9.2 out of 100, which is about as close to zero as you can get without being a calculator.

vs Competition
Against the Apple MacBook Pro MVVK2LL/A, this thing loses on raw performance and storage, but it's also a fraction of the price at the low end. The Lenovo ThinkPad X1 Carbon 21KC00A8US is a more direct competitor in build quality and portability, but it runs Windows and costs significantly more. The Samsung Galaxy Book4 Edge NP960XMA-KB1US has a better CPU and more storage, but you're paying for it. The HP OmniBook 3 14-HZ0015DX/D0VF2UA#ABA is closer in spirit, but the ASUS screen is better. The Microsoft Surface Laptop 165H is the premium Windows alternative, and it beats the ExpertBook on CPU and storage, but not on value if you catch the ASUS on sale.

Prix
Value & Pricing
Pricing is all over the place. We're seeing listings from USD 238 to USD 800 across five US vendors. At the low end, this is an absolute steal for the screen and build quality alone. At the high end, you're paying ultrabook money for a Chromebook, and that's a harder sell. If you can find it closer to USD 238, grab it without hesitation. If you're staring down USD 800, you need to really love ChromeOS to justify it.
En savoir plus
Overview
The ASUS ExpertBook CX54 is a Chromebook that thinks it's a premium ultrabook. You get a 14-inch 2560x1600 IPS display with 500 nits of brightness and 120Hz refresh, an all-metal chassis, and military-grade durability. That screen alone puts it in the top tier of Chromebooks we've tracked, and the build quality backs it up.
But here's the catch. It's running ChromeOS with a Core Ultra 5 processor, 16GB of RAM, and only 256GB of storage. That's a lot of horsepower for an OS that mostly lives in a browser. For the right person, that's overkill in the best way. For everyone else, it's a mismatch.
Common Questions
Q: Can this run Windows or Linux apps?
It runs ChromeOS, so you're limited to web apps, Android apps, and Linux apps via the built-in container. Full Windows apps are not an option.
Q: Is 256GB of storage enough?
For most ChromeOS users, yes, since the OS is lightweight and Google Drive integration is built in. But if you download a lot of media or install many Android apps, you'll feel the squeeze quickly.
Q: How is the battery life in real-world use?
ASUS claims up to 10 hours, but the 45Wh battery is on the smaller side. Expect closer to 6-8 hours with the bright display and 120Hz refresh rate active.
Who Should Skip This
Skip this if you need to run Windows or macOS software, play any kind of modern game, or store large files locally. The 256GB SSD and integrated graphics are dealbreakers for those use cases. Also skip it if you're paying near the USD 800 mark, because at that price you can get a proper Windows ultrabook with more storage and a better CPU.
Verdict
This is for the ChromeOS diehard who wants premium hardware without paying MacBook prices. If you live in Google Workspace, use Android apps, and want a laptop that looks and feels expensive, this is a great pick. The screen is genuinely excellent, the build is solid, and 16GB of RAM means you'll never feel cramped. Just don't expect to play games or store a massive media library locally.
