Lisa Gade reviews the Lenovo ThinkPad P53, a 15.6” mobile workstation that’s extremely powerful and upgradable. The laptop is available with Intel 9th gen Core i5, i7 and i9 processors and the Intel Xeon 8-core E-2276M CPU. It ships with NVIDIA Quadro graphics, at the low end the T1000/T2000 and at the upper end there’s the Quadro RTX 3000, RTX 4000 Max-Q and RTX 5000 Max-Q with 16GB DDR6 VRAM. It’s currently the only 15” mobile workstation with the Quadro RTX 5000, which is the model we have for review. The ThinkPad is available with full HD and 4K UHD displays, including a 4K OLED option. The P53 is designed for 2D and 3D CAD, modeling, architecture and 3D rendering.
