Lenovo ThinkPad X1 Carbon 14" X1 Carbon 5th Gen 2016

At 1.13kg, this is one of the most portable laptops in our database, landing in the 88th percentile for compactness. The trade-off is 8GB of RAM that ranks in the bottom 5% and a dual-core CPU that's strictly for light work. It's a writer's dream chassis at a sub-$400 refurbished price, but a multitasker's nightmare.

Let's be real about what this machine can and can't do. The i7-6600U is a dual-core chip from the Skylake era, sitting right in the middle of our database at the 54th percentile for CPU performance. Paired with integrated Intel HD 520 graphics, which land in the 16th percentile, this is strictly a productivity and web browsing machine. Our gaming score of 9.5 out of 100 tells you everything you need to know. The 8GB of RAM is the real bottleneck here, ranking in the bottom 5% of all laptops we've tested. You'll feel that with more than a handful of browser tabs open. The 256GB SSD is snappy enough for booting Windows 10 Pro, but its 19th percentile ranking means it's small and likely not the fastest NVMe drive by modern standards.

Stacked against modern competitors like the Apple MacBook Air M4 or the Microsoft Surface Laptop 7th Edition, the X1 Carbon gets absolutely demolished in performance. Those machines are in a different universe for CPU and GPU power, not to mention battery life. But they also cost over three times as much. The real competition for this refurbished ThinkPad is other used business laptops in the $300-$400 range. Against a similarly priced Dell Latitude or HP EliteBook from the same era, the X1 Carbon's 88th percentile compactness and superior keyboard give it a clear edge. You're choosing portability and typing feel over raw specs, and for the right person, that's a fair trade.

Pricing on these refurbished units floats between $323 and $418 depending on the config and seller. For a sub-$400 laptop, the build quality and portability are genuinely impressive. You're getting a premium chassis that cost north of $1,500 when new. Just know that the 8GB RAM model is a tough sell even at this price, and we'd strongly suggest hunting down the 16GB variant if you can find it in stock. The value proposition hinges entirely on your willingness to trade raw performance for a featherweight, well-built typing machine.

The ThinkPad X1 Carbon 5th Gen lands in the 88th percentile for compactness, and at 1.13kg, it's a featherweight that genuinely disappears into a bag. That's the headline here. You're getting a 14" IPS display and that legendary ThinkPad keyboard in a chassis that's still thinner than most modern ultrabooks. But this is a refurbished unit from 2017, and the internals show their age. The dual-core i7-6600U and 8GB of LPDDR3 put it in the 54th and 5th percentiles respectively, so expectations need to be set accordingly.

Anyone who keeps more than ten browser tabs open should look elsewhere. The 8GB of RAM is a serious choke point, ranking in the 5th percentile, and you'll feel the system crawl under even moderate multitasking. If you need to run Slack, Zoom, and a browser simultaneously, this machine will struggle. Gamers, video editors, and anyone working with large spreadsheets should also steer clear, the integrated graphics and dual-core CPU just aren't built for it. Even at this low price, a used T-series ThinkPad with upgradeable RAM would be a smarter buy for most people.

The ThinkPad X1 Carbon 5th Gen is a purpose-built machine for writers, students, and anyone who values a great keyboard and a lightweight chassis above all else. Our data shows it's a standout for portability and reliability, but the 8GB RAM and aging dual-core CPU mean it's a one-thing-at-a-time kind of laptop. If your workflow lives entirely in a browser and a text editor, this is a fantastic deal. If you need to run anything more demanding, the bottom-tier RAM and storage rankings will frustrate you daily.
