Lenovo’s ThinkPad X1 Carbon line dates again to 2012, and now, in its Twelfth incarnation, the laptop computer has reached a degree of maturity few other brands can boast. Today’s X1 Carbon has been honed to a wonderful level—but it will be legitimately tough to tell apart from the unique. I’d know, as a result of I reviewed it for WIRED approach again when.

The tune writ massive stays the identical as ever. This is Lenovo’s flagship ultralight, the enterprise laptop computer designed to kill all others. It retains the identical dimension 14-inch LCD (with 16:10 facet ratio, now at 2,880 x 1,800 pixels) that it has all the time had, with the burden now hitting 2.2 kilos— exhibiting a wholesome and regular weight reduction through the years.

I measured the thickness at 21 millimeters, largely owing to a large rubber foot that runs alongside the again of the bottom to prop the keyboard up a bit. The present chassis, in Lenovo’s phrases, is constructed from “recycled aluminum, magnesium, aerospace-grade carbon fiber, as well as post-consumer materials that are used throughout its construction.”

Many different improvements listed below are incremental at greatest. I imply, when the model begins speaking about “new tactile markings” on the keyboard—these little bumps on the F and J keys— we’re getting near an innovation terminus. There’s additionally a small ridge that juts out on the high of the display screen the place the webcam (that includes a guide shutter) seems, plus a relocated fingerprint reader, however some other beauty adjustments are robust to suss out.

The large information is underneath the hood, with the inclusion of the brand new Intel Core Ultra CPU, this mannequin that includes an Ultra 7 155H chip operating at 1.4 GHz. A small brigade of producers is dropping machines with Ultra chips this month, with the large pitch being round synthetic intelligence efficiency, higher energy effectivity, and improved built-in graphics. AI-driven benchmarks are nonetheless a brand new factor, so till I’ve a good base of outcomes to attract from, I’m reporting on my customary battery of exams that blend varied enterprise apps and graphics benchmarks.
