HP 255 G8 Ryzen 5 business laptop

The HP 255 G8 is a 15.6 inch laptop built around a 6-core AMD Ryzen 5 5500U processor with 16 GB of DDR4 memory and a 1 TB PCIe NVMe solid-state drive. It ships with Windows 10 Pro 64-bit and a non-touch Full HD IPS display. The configuration suits office workers, students and remote professionals who need a ready-to-use machine for productivity applications and video calls.

Sustained workload behaviour

The 5500U operates at a 2.10 GHz base frequency and can reach 4 GHz turbo across its six cores and twelve threads, supported by 12 MB of L3 cache. Under continuous multi-threaded load such as large spreadsheet recalculations or background compiles, the integrated AMD Radeon graphics share system memory while the CPU maintains clocks within the 45 W power envelope. Performance scales with the cooling solution rather than a discrete GPU.

Thermals noise and power

A 45 W adapter charges the 3-cell 41 Wh battery while the chassis measures 14.10 by 9.53 by 0.88 inches and weighs 3.8 lb. In typical office use the fan remains audible but not intrusive, and surface temperatures stay comfortable on the palm rests. The 60 Hz panel and integrated graphics keep average power draw modest, allowing several hours of unplugged work before the battery requires recharging.
