16.0" WQXGA IPS mobile workstation

The Lenovo ThinkPad P1 Gen 4 is a 16.0-inch mobile workstation built around an Intel Xeon W-11855M processor with six cores and 18 MB of L3 cache. It ships with 32 GB of DDR4 3200 memory in a single module and a 1 TB PCIe solid-state drive. Graphics are handled by a dedicated NVIDIA RTX A2000 with 4 GB of video memory. The matte IPS panel delivers 2560 x 1600 resolution at 400 nits with full sRGB coverage and low blue light support.

Professionals needing ISV-certified stability

This system suits engineers, designers and analysts who rely on workstation-class drivers and ECC-capable Xeon silicon for CAD, simulation or content-creation workloads. The Thunderbolt 4 ports and single free memory slot allow peripheral expansion and a future upgrade to 64 GB total capacity. Buyers who need more than 64 GB of memory or require multiple GPU configurations should look at larger chassis workstations.

Single-module 32 GB DDR4 3200 with one open slot

Memory ships as one 32 GB DDR4 3200 module occupying one of two slots, leaving the second slot free for a straightforward upgrade to the 64 GB maximum supported by the platform. This configuration matters because dual-channel bandwidth is not active until the second slot is populated, so performance-sensitive users should plan to add a matching module.
