Lenovo ThinkPad P16s Gen 4 21QV0032US laptop Intel Core Ultra 7 255H 16GB DDR5 512GB SSD

Mobile workstation with Arc graphics

The Lenovo ThinkPad P16s Gen 4 21QV0032US is a 16.0 inch mobile workstation running Windows 11 Pro. It targets professionals who need ISV-certified stability and AI Boost acceleration in a portable chassis. Buyers who require a discrete GPU with dedicated video memory or a touchscreen display should look elsewhere.

Intel Core Ultra 7 255H processor

The single specification that decides fit is the Intel Core Ultra 7 255H CPU with a 5.10 GHz turbo frequency and 16GB of DDR5 5600 memory. This combination determines whether the system can handle your specific multi-threaded workloads and memory bandwidth requirements. The integrated Intel Arc 140T GPU shares system memory rather than providing its own VRAM pool.

Sustained load on integrated graphics

Under sustained load the Intel Arc 140T GPU draws from the same 16GB DDR5 pool as the CPU, so thermal throttling and memory bandwidth contention become the limiting factors. The 60 Hz WUXGA IPS panel at 1920 x 1200 resolution does not increase GPU demand during extended render or compute sessions. Wi-Fi 7 connectivity maintains network throughput without adding thermal load to the SoC.
