More performance and a very good display. Lenovo's ThinkPad P51 is a full-fledged mobile workstation with a 15-inch display, powerful Xeon quad-core processor and a professional graphics card from Nvidia. The 4K screen in particular convinced in the review.

There is no question that the Lenovo ThinkPad P51 is an impressive 15.6-inch mobile workstation and one of the top-performing contenders in its class. The 15.6-inch form factor is very popular among mobile workstation users, especially when it offers crystal-clear 4K resolution, and although it's not super light, it’s easy enough to take on the road. Those who crave still more power at the expense of some portability can check out the larger, heavier model P71.

Overall, the ThinkPad P51 combines excellent workstation-grade performance into a solid 15.6-inch chassis that can take a beating. We’d like to see it come with a longer standard warranty period than one-year, but otherwise have little to complain about.

The ThinkPad P51 combines workstation-class general performance and graphics with a colorful display, durable design, wide port selection and all-day battery life. We wish that the laptop were lighter, that its screen were a bit brighter, and that we could access the power and Thunderbolt ports without reaching around to the back, but power-hungry users can easily deal with these trade-offs.
