For the original German review, see here.

Lenovo has only cautiously updated its workstation lineup this year since there was a major redesign last year. Unlike the ThinkPad P51s (here in review), which has put a bigger focus on the mobility, it is all about the performance with the ThinkPad P51. This is supported by the powerful quad-core processors and faster professional graphics cards, but they are still based on Nvidia's old Maxwell architecture.

Our review unit today is currently one of the most powerful SKUs of the ThinkPad P51 with a mobile Xeon processor (Kaby Lake), Nvidia Quadro M2200M GPU, fast PCIe SSD and high-resolution 4K screen with integrated calibration. However, all this comes at a price. Regular customers pay around 3300 Euros (~$3671); students and eligible scientific employees can get it for 2700 Euros (~$3005).

The biggest rivals are obviously the classic mobile workstations from Dell, HP, or Fujitsu, but we have not been able to review their current models so far. We therefore use the predecessors Dell Precision 7510, HP ZBook 15 G3, and Fujitsu Celsius H760. We also want to check what compromises you have to make by choosing a slimmer & lighter alternative such as the Dell Precision 5520 or the previously mentioned ThinkPad P51s.

The basic construction of the ThinkPad P51 has not changed compared to the previous ThinkPad P50, so we will not cover all the sections in this article and only talk about the changes. We recommend our comprehensive reviews of the ThinkPad P50 for more information:
