EliteBook 645 G9 14-inch FHD laptop

This HP EliteBook 645 G9 is a new 14-inch mainstream laptop with a 1920 x 1080 antiglare display rated at 250 nits and 45% NTSC coverage. It runs Windows 11 Pro on an AMD Ryzen 5 PRO 5675U six-core processor that reaches 4.3 GHz, paired with 24GB of DDR4-3200 memory and a 256GB SSD. Integrated AMD Radeon graphics use shared system memory.

Before ordering check memory and storage needs

The 24GB of DDR4-3200 memory is soldered and not expandable, so confirm that capacity suits your workload before purchase. The single 256GB SSD provides the only internal storage; verify this space is sufficient or plan for external drives. Wireless connectivity uses Realtek RTL8852BE 802.11ax (2x2) Wi-Fi and Bluetooth 5.2, while wired LAN is limited to 10/100/1000Mbps.

Sustained load thermal behaviour

Under prolonged heavy load the six-core processor will likely hit thermal limits and reduce clock speeds below the 4.3 GHz maximum boost. Integrated Radeon graphics share the same thermal budget and system memory bandwidth, so extended gaming or compute tasks will throttle further. The 250-nit panel and 45% NTSC colour gamut remain unchanged regardless of load.
