Performance
The Core Ultra 7 155U is a 12-core chip that handles spreadsheets, browser tab hoarding, and video calls without breaking a sweat. Our database puts the CPU right around the middle of the pack, which sounds underwhelming until you remember this thing weighs barely over a kilogram. The integrated Intel graphics are fine for productivity but don't expect to game on this, our gaming score of 19.7 out of 100 tells you everything you need to know there. The 512GB SSD is on the smaller side, landing in the bottom half of our storage rankings, so you might want to budget for cloud storage or an external drive.

vs Competition
Against the Apple MacBook Pro M2 Pro, the X1 Carbon wins on weight and keyboard feel but loses badly on raw performance and battery consistency. The HP OmniBook X Flip and ASUS Zenbook UX3405CA offer similar portability with newer designs, but neither matches the ThinkPad's keyboard or build reputation. The Microsoft Surface Laptop 7 has a better display and more modern chip, but you're giving up the X1's superior port selection. The Samsung Galaxy Book4 Edge is lighter on paper but feels flimsier in hand. For pure travel-focused productivity, the X1 Carbon still holds its own, but it's no longer the undisputed king it once was.

European buyers face a tighter but still notable gap, with EUR prices ranging from EUR 2,371 to EUR 2,879 across three listings. The best deal we're seeing is at the lower end of the US range, so shop around before you commit.

Overview
The ThinkPad X1 Carbon Gen 12 is the laptop you buy when you're tired of lugging around a brick and want something that feels like it belongs in first class. At 1.08kg, it's absurdly light, and the 14-inch 1920x1200 display gets bright enough at 400 nits to handle a sunny window seat. The Intel Core Ultra 7 155U with 16GB of LPDDR5X RAM keeps things snappy for everyday work, and that legendary ThinkPad keyboard is still the best typing experience on a thin-and-light.
Common Questions
Q: Can this laptop handle gaming or video editing?
Not really. The integrated Intel graphics score just 19.7 out of 100 in our gaming tests, so it's fine for basic photo edits and streaming but not for modern games or heavy video work.
Q: Is 512GB of storage enough?
It's workable for documents, apps, and a modest media library, but it lands in the bottom half of our storage rankings. If you keep lots of large files, plan on cloud storage or an external SSD.
Q: How does the battery actually hold up in real use?
The 57Wh battery delivers good but not great endurance. Most owners get through a full workday of typical use, though some report inconsistent results, especially under heavier loads or with the screen at full brightness.
Who Should Skip This
Skip this if you need any kind of graphics horsepower, the gaming score of 19.7 out of 100 should be a dealbreaker for anyone who wants to play games or do serious video editing. Also look elsewhere if you need lots of local storage, since 512GB fills up fast and there's no easy way to upgrade it. And if you're the type who gets frustrated by occasional hardware quirks, the reported touchpad and power-on issues might drive you up the wall.
Verdict
Buy this if you're a frequent traveler or office worker who types all day and wants a laptop that won't weigh you down. The keyboard alone is worth the price of admission for writers, coders, and email warriors. Just know that you're trading gaming performance and storage headroom for that portability. If you can find it at a good price, it's one of the best ultrabooks for getting real work done on the go.
