Latitude 7490 14-inch Touch Ultrabook

The Dell Latitude 7490 is a 14-inch business ultrabook with a touchscreen display. It runs Windows 10 Pro on an 8th Generation Intel Core i7-8650U quad-core processor. Sixteen gigabytes of DDR4 2400 memory and a 256 GB solid-state drive handle daily workloads. Integrated Intel UHD Graphics drives the 1920 x 1080 anti-glare panel.

Sustained load on 15-watt quad core

The i7-8650U operates at a 15 W thermal design power with a base frequency of 1.90 GHz and a maximum turbo of 4.20 GHz. Under continuous multi-threaded work the processor settles near its base speed to stay within the thin chassis limits. The 3-cell 42 W battery supplies mobile runtime for typical office tasks. Active cooling manages heat during extended sessions.

Upgrade from dual-core or spinning disk

Buyers moving from a dual-core ultrabook or a hard-drive laptop gain four cores and solid-state responsiveness. The 16 GB memory ceiling suits heavy multitasking and virtual machines. The carbon-fibre chassis keeps weight near 1.4 kg for frequent travel. Users who need discrete graphics, larger storage or user-replaceable memory should consider other form factors.

Questions about this item

How loud and hot does the 15 W i7-8650U get during all-day workloads?

The quad-core 1.90 GHz processor runs at 15 W base power with a 4.20 GHz turbo, so sustained loads stay within a thin 14" chassis cooled by a single fan.

Which peripherals and cables must I already own to use the 14" FHD touchscreen and 256 GB SSD immediately?

The box includes the 65 W worldwide AC adapter, 125 V US power cord, and a 3-cell 42 Wh battery; no other cables or adapters are required for basic operation.

Will the Intel UHD Graphics and 802.11ac wireless card work with my older 1080p monitors and router?

Integrated UHD Graphics drives external displays up to 4K over HDMI or USB-C alt-mode, while the Intel 8265 2x2 802.11ac card connects to any 802.11a/b/g/n/ac access point.
