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.

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.
