The ThinkPad P1, mobile workstation sibling to the X1 Extreme, has also seen a recent refresh. We take a close look to see where the two laptops differ.

Lenovo's attack on the 15-inch powerhouse Ultrabook market includes both the second-gen ThinkPad X1 Extreme and ThinkPad P1, two devices that are almost identical yet are geared for different usage scenarios. I recently reviewed the X1 Extreme (Gen 2), ultimately handing it a Best Award thanks to its balance of design, features, and performance.

While the X1 Extreme's internal hardware is more geared toward the average user who likes extra power, the ThinkPad P1 (Gen 2) counterpart is a truer mobile workstation with internal hardware meant to work with specialized professional software. I made the switch to the P1 more than a week ago to test it out and decided that a standard full review would be redundant.
