Built for mobile professionals

The HP ProBook 640 G4 is a 14.0 inch ultrabook running Windows 11 Pro. It pairs an Intel Core i5-8350U quad-core processor with 32 GB of DDR4 memory. Storage combines a 512 GB M.2 drive and a 1 TB SSD. The 1920 x 1080 IPS panel offers wide viewing angles without touch input.

Sustained workload behaviour

The i5-8350U operates at a 1.70 GHz base frequency and can reach 3.60 GHz on turbo. Intel UHD Graphics 620 handles integrated visual tasks. Under continuous load the ultrabook chassis manages heat from the 6 MB L2 cache processor. Wi-Fi 5 and Bluetooth 4.1 maintain wireless connectivity during long sessions.

Build and daily connectivity

A silver aluminium unibody houses the components. Video output uses HDMI and the USB 3.1 Type-C Gen 1 port with DisplayPort and Power Delivery. Three USB 3.1 Gen 1 Type-A ports connect peripherals. Gigabit Ethernet, a webcam and the non-touch display complete the physical interface set.
