Lenovo ThinkPad X1 Carbon Gen 8 Review
There are lots of good laptops 45n1700, but it’s rare to find one repeatedly described as the best laptop you can buy. The eighth generation of Lenovo’s ThinkPad X1 Carbon (starts at $1,331; $1,888 as tested) carries that history, having racked up more rave reviews and awards than any notebook we can think of except possibly the Dell XPS 13.
This 14-inch business system combines an unbeatable screen and keyboard with MIL-STD 810G toughness to pass torture tests involving shock, vibration, and environmental extremes, yet it weighs just 2.4 pounds, less than the XPS 13 and many other ultraportables. With stacks of as-you-like-it configuration options, it picks up PCMag Editors’ Choices as regularly as punching a time clock.
This year is no exception, though we’re sad Lenovo keeps sending us relatively modest Core i5 models. Maybe year we’ll get to review a fancy loaded version.
Today’s test unit features a 1.7GHz Core i5-10310U processor, 8GB of memory, a 256GB NVMe solid-state drive, and a full HD (1,920-by-1,080-pixel) non-touch IPS display. Our Lenovo rep says it’s $1,888 from CDW, which seems a tad steep compared to Lenovo.com’s base model at $1,331 (a few dollars cheaper with Linux).
The extra $557 buys you a trivially faster Core i5 with Intel’s vPro remote IT management, Windows 10 Pro instead of Home, and LTE mobile broadband. If you don’t need the LTE, you would see little difference with the starter machine.
Lenovo offers four other screen options: 45n1700 a 1080p touch screen, a 1080p touch screen with a privacy filter, a higher-resolution 2,560-by-1,440-pixel panel, and a 4K (3,840-by-2,160-pixel) Dolby Vision HDR 400 display. The memory and storage ceilings are 16GB and 1TB respectively; Lenovo.com’s price for a maxed-out Core i7-10610U system with the 4K screen is $2,378.
Though the lightest of Lenovo’s three 14-inch business notebooks (under the 2.8-pound ThinkPad T14s and 3.2-pound ThinkPad T14), the Carbon isn’t the lightest on the market; the Asus ExpertBook B9450 is just 1.91 pounds. Still, at 0.59 by 12.7 by 8.5 inches the Lenovo is impressively compact (the Acer TravelMate P6 measures 0.65 by 12.8 by 9.1 inches). It’s a breeze to stash in any briefcase.
Unlike some other ultralights, the magnesium-reinforced-with-carbon-fiber ThinkPad doesn’t feel flimsy; there’s no flex if you grasp the screen corners or press the keyboard deck. An X1 insignia below the lid’s diagonal ThinkPad logo is the only change in the familiar matte-black design. The screen bezels are thin, with a webcam with sliding shutter above the display; the face-recognition camera and a small fingerprint reader beside the touchpad give you two ways to skip passwords with Windows Hello.
On the laptop’s 45n1700 left side are two Thunderbolt 3 ports, a connector for a $35 Ethernet dongle, a USB 3.2 Type-A port, an HDMI video output, and a headphone/microphone jack. Another, always-on USB-A 3.2 port is at the right, along with the power button and a Kensington cable-lockdown slot. A bent paper clip removes a tiny tray at the rear that holds the optional SIM card.
The 720p webcam captures good color and is free of digital noise, but the picture is soft-focus, bordering on blotchy. Two upward-firing tweeters and two downward-firing woofers pump out above-average sound, with plenty of volume and a modest amount of bass; highs and midtones are clear and it’s easy to distinguish overlapping tracks. Supplied Dolby software lets you switch among music, movie, dynamic, game, and voice presets or play with an equalizer.
The 14-inch display is nice and sunny as long as you stick to the top couple of brightness settings, with good contrast and satisfactory if not dazzling white backgrounds. Fine details are as sharp as the 1080p resolution permits and viewing angles are broad. Colors don’t quite pop but are rich and well saturated.
Except for the Fn and Control keys being in each other’s place at bottom left (you can swap them with the provided Lenovo Vantage software, which combines a handful of utilities with system updates and Wi-Fi security), the backlit keyboard is faultless.
The top row combines function keys for volume and brightness with shortcuts for answering and hanging up on calls in Skype for Business and Microsoft Teams, 45n1700 as well as dedicated Home and End keys (Page Up and Page Down are next to the cursor arrows).
Typing feel is swift and snappy, a bit shallow but with good tactile feedback. Cursor jockeys can as usual choose between the buttonless, slightly small touchpad and three-button TrackPoint embedded mini joystick, both of which are perky and precise.
For our benchmark comparisons, I matched the ThinkPad X1 Carbon Gen 8 against four other 14-inch business laptops ranging from Lenovo’s own ThinkPad T14s (whose eight-core AMD Ryzen 7 Pro processor makes it the favorite in our CPU tests) to the Dell Latitude 7410 and abovementioned Acer TravelMate P6 and Asus ExpertBook B9450.
