Sibling Rivalry: Lenovo ThinkPad P50 Review

Just as we were finishing our review of the P70, Lenovo sent us its ThinkPad P50, the new 15.6-in. addition to the P series line of mobile workstations. Other than its smaller size (14.86x 9.93 x1.02 in.) and weight (5.72 lbs.), it is nearly identical to its larger sibling. Thanks to its smaller 170-watt power supply, total weight is just a fraction over 7 lbs.

Although base P50 configurations start at $1,322 for a system with a 2.6GHz Core i7 quad-core CPU, a 1920x1080 display, an NVIDIA Quadro M1000M GPU, 8GB of RAM and a 500GB 7200rpm drive, we received a fully-loaded version equipped with the same 2.8GHz Intel Xeon E3-1505M v5 Skylake processor, a 15.6-in. version of the gorgeous 4K UHD (3840x2160) IPS (in-plane switching) display panel, 16GB of 2133MHz ECC memory and a 512GB SSD (solid-state drive) PCIe-MVMe. Our ThinkPad P50 even included the color sensor and X-Rite Pantone calibration software like the P70.

In fact, the only significant difference between the P50 and P70 systems we received were the graphics. Our P50 came with an NVIDIA Quadro M2000M equipped with 4GB of GDDR5 memory and 512 CUDA cores. The ThinkPad P50 can accommodate up to 64GB of memory and two SSDs.

The right side of the P50 provides a single audio jack, two USB 3.0 ports, a mini DisplayPort connector, and a security lock slot, while the left side houses only an ExpressCard slot, SDXC slot and an optional Smart Card reader. The rear panel provides a single Thunderbolt 3/USB Type C connector, HDMI port, RJ45 Ethernet jack, two USB 3.0 ports including one that can charge devices, and the power connector. The bottom of the case features a docking port and a removable 6-cell battery that kept our system running for 4.6 hours.

Although equipped with the same CPU, memory and hard drive as the P70, the less-powerful GPU caused the ThinkPad P50 to lag behind its big brother in our benchmarks. That said, the P50 still outperformed most systems we tested last year. With a price as tested of just $2,353 the P50 is a great mobile system with ample power that is easier to carry and more affordable than its larger sibling.
