Large-screen workstation
The HP OmniBook 3 is a 17.3-inch laptop built around an Intel Core Ultra 7 255U 12-core processor with 16GB DDR5 memory and a 2TB SSD. It runs Windows 11 Pro and uses integrated Intel Graphics on a Full HD IPS anti-glare panel. The chassis includes a full-size backlit keyboard with numeric keypad and an HD webcam.
Desk-based professionals, not mobile creators
This machine suits office workers, students and analysts who want a single large display for spreadsheets, documents and video calls without an external monitor. Buyers who need discrete graphics for 3D rendering, video editing or gaming should look elsewhere, as should anyone who requires a lightweight device for daily commuting or a touchscreen for pen input.
12-core processor with 5.20GHz turbo
The Intel Core Ultra 7 255U delivers 12 cores and a maximum turbo frequency of 5.20GHz, supported by 12 MB Intel Smart Cache. This specification determines whether the laptop can handle heavy multithreaded workloads such as large dataset analysis, virtualisation or code compilation within its integrated thermal envelope.

Questions about this item
How loud does the Core Ultra 7 255U fan get during long work sessions?
The 12-core processor runs at a 2.00 GHz base and can boost to 5.20 GHz. Under sustained load the integrated Intel Graphics share the same thermal budget, so the fan will spin up but remains in line with typical 17.3" ultraportable acoustics.
Which cables or docks do I need to connect two external monitors?
The laptop provides one HDMI port and two USB Type-C 3.1 ports. Each Type-C carries DisplayPort alt-mode, so you can drive two extra displays using a dual-monitor dock or two separate USB-C to HDMI adapters.
Will my older USB 3.0 flash drives and Bluetooth 5 headphones work without extra drivers?
Yes. Two USB 3.0 Type-A ports accept legacy flash drives directly, and the built-in Bluetooth 5 radio pairs with existing headphones, keyboards or mice automatically under Windows 11 Pro.
