HP OmniBook 3 17.3" laptop for mobile professionals

The HP OmniBook 3 17-dg0107dx is a 17.3-inch laptop built around an Intel Core Ultra 7 255U 12-core processor with a 5.20GHz turbo frequency. It ships with 32GB of DDR5 memory and a 1TB SSD running Windows 11 Pro. The anti-glare IPS panel delivers a 1920 x 1080 resolution for clear viewing in varied lighting.

Suited for users who need a large screen

This configuration suits office workers, students and remote staff who value display real estate and multi-tasking headroom over discrete graphics power. Buyers who need a dedicated GPU for rendering, gaming or GPU-accelerated workloads should look at a different class of machine. The integrated Intel Graphics and lack of a touchscreen also limit suitability for stylus-based creative work.

12-core processor with 5.20GHz turbo decides

The Intel Core Ultra 7 255U provides 12 cores and 12MB of Smart Cache, reaching 5.20GHz on turbo. That single specification determines whether the laptop can handle your parallel workloads, compile times or virtual machines within the thermal envelope of a slim 17.3-inch chassis.
