Ready for office work

The HP ProBook 645 G4 is a 14-inch laptop built around a Ryzen 5 PRO 2500U quad-core processor running at a 2 GHz base frequency with a 3.6 GHz boost. It ships with 16 GB of DDR4-2400 memory and a 512 GB SSD, running Windows 11 Pro out of the box. The integrated Radeon Vega 8 graphics share system memory for everyday visual tasks.

Stepping up from limited memory or hard drives

This configuration replaces machines constrained by 8 GB of RAM or mechanical storage, delivering a noticeable jump in multitasking headroom and boot speed. The upgrade is worth it when your workflow keeps multiple browser tabs, office suites and background services open simultaneously. Buyers who need discrete graphics performance for rendering or gaming will not find it here.

HD panel and single-stream wireless set practical

The 1366 x 768 anti-glare display covers 45% NTSC at 220 cd/m², limiting colour-critical work and side-by-side window clarity. Wireless-AC 3168 provides 1x1 802.11ac connectivity with Bluetooth 4.2, so throughput peaks at single-stream rates. Users needing higher colour fidelity or multi-antenna Wi-Fi should plan accordingly.
