HP OmniBook 3 17.3" business laptop Intel Core Ultra 7 255U 32GB DDR5 512GB NVMe Windows 11 Home

Large-screen business laptop

The HP OmniBook 3 delivers a 17.3-inch Full HD IPS display in a chassis weighing 4.43 lb, making it practical for professionals who need ample screen space for spreadsheets or presentations without a desktop monitor. It runs Windows 11 Home on an Intel Core Ultra 7 255U processor with 12 cores and 14 threads, supported by 32 GB of DDR5 memory and a 512 GB NVMe SSD.

Sustained workload behaviour

The 12-core Ultra 7 255U maintains up to 5.2 GHz boost clocks across its 12 MB cache, allowing extended compile, rendering or data-analysis sessions to progress without the sharp frequency drops seen in burst-only designs. Integrated Intel graphics handle multi-monitor output through HDMI 2.1 and two USB-C 3.1 ports while the 32 GB DDR5 pool keeps large datasets resident, reducing swap activity during long runs.

Thermals, noise and power

A 45 W power supply feeds the 3-cell battery, keeping typical office workloads well within the thermal envelope so fan noise stays low in quiet environments. The slim 0.65-inch profile distributes heat across a broad surface area, preventing localised hotspots during video calls or continuous background tasks. Wi-Fi 7 and Bluetooth 5.0 connectivity add minimal power draw, preserving battery life for mobile use.
