The new first-generation ThinkPad X13 looks a whole lot like the other ThinkPads, but it's packing AMD Ryzen 4000 PRO processors for a big performance boost.

The Lenovo ThinkPad X lineup — not to be confused with the high-end ThinkPad X1 lineup that includes the X1 Carbon, X1 Extreme, and X1 Yoga — is meant to appeal to those who want a thin and light business laptop with extra security features and coveted ThinkPad durability. X-series laptops, which include standard and Yoga versions of the ThinkPad X390, ThinkPad X395, and ThinkPad X13 (which I'm reviewing here), are a lot closer to Lenovo's T-series devices than the expensive X1 line. The X13 starts at an affordable price, it's sized to travel, and it's packing hardware cut out for productivity work. I've been using a ThinkPad X13 with AMD Ryzen 4000 PRO CPU for about a week to see what it's all about and, ultimately, whether or not it's worth a buy.
