HP OmniBook 3 17.3" Core Ultra 7 255U 16GB 1TB Windows 11 Pro

17.3-inch Business Laptop

The HP OmniBook 3 is a 17.3-inch laptop built for business users who need a large screen and reliable everyday performance. It ships with Windows 11 Pro and an Intel Core Ultra 7 255U processor with 12 cores and 14 threads. The system includes 16GB of DDR5 memory and a 1TB NVMe SSD for fast storage. A Full HD IPS display provides clear visuals for office tasks and video calls.

Thermals and Power in Daily Use

A 45W power supply supports the Ultra 7 255U and its integrated graphics during typical workloads. The 3-cell battery keeps the system running away from a desk for standard business hours. Wi-Fi 7 and Bluetooth 7 maintain stable wireless connections without adding noticeable heat. The chassis stays quiet during document editing, web browsing and video conferencing.

Behaviour Under Sustained Load

The 12-core processor maintains its 5.2GHz boost across extended compile, render or analysis jobs. Integrated graphics share system memory, so long GPU-accelerated sessions reduce the RAM available for other tasks. The 1TB NVMe drive delivers consistent throughput without thermal throttling during large file transfers. Buyers who need discrete graphics or more than 16GB of memory should consider a different configuration.
