HP OmniBook 3 17.3" Intel Core Ultra 7 255U 16GB DDR5 512GB Windows 11 Pro

Business AI laptop for everyday productivity

The HP OmniBook 3 is a 17.3 inch business laptop built around an Intel Core Ultra 7 255U processor with twelve cores and fourteen threads reaching up to 5.2 GHz. It ships with 16GB of DDR5 memory and a 512GB NVMe solid state drive. A 1920 x 1080 IPS display and Windows 11 Pro complete a configuration aimed at office work and video conferencing.

Thermals and power in typical office use

The chassis measures 15.65 by 10.09 by 0.65 inches and weighs 4.43 pounds, housing a 45 watt power supply and a three cell battery. Integrated Intel graphics handle the Full HD panel without a discrete GPU, keeping heat output modest during document editing, web browsing and Teams calls. Fan noise stays low enough for open plan environments while Wi-Fi 7 and Bluetooth 5.0 maintain wireless links.

Behaviour under sustained workloads

Under continuous multi threaded loads the Ultra 7 255U maintains its turbo frequencies within the limits of the slim cooling assembly. Surface temperatures rise above idle but remain within comfortable limits for lap use. The 512GB NVMe drive sustains sequential throughput without throttling, and the 720p webcam continues to deliver a stable image during long meetings. Buyers who need more storage or discrete graphics for rendering should consider other form factors.
