Professional ultraportable

The Dell Latitude 7490 is a 14.0 inch business laptop built for mobile professionals who need a durable chassis and long support coverage. It ships with Windows 10 Pro and a three-year in-home service warranty that runs until late 2021. The quad-core Intel Core i7-8650U processor runs at a 1.90 GHz base with a 4.20 GHz maximum turbo frequency. Sixteen gigabytes of DDR4 2400 memory and a 256GB solid-state drive handle everyday workloads without delay.

Target user and limits

This configuration suits office workers, remote administrators and students who value a lightweight magnesium-alloy frame, a backlit dual-pointing keyboard and a 65 watt worldwide power adapter. Buyers who need a dedicated graphics processor for rendering or gaming should look elsewhere. The non-touch 1920 x 1080 anti-glare panel lacks pen support, so creative users requiring inking must choose a different model. Thunderbolt and 802.11ac wireless are present, but the integrated Intel UHD Graphics cannot drive high-refresh external displays.

Deciding specification

The single figure that determines fit is the 16GB DDR4 2400 memory capacity because it is soldered and cannot be upgraded after purchase. If your workflow regularly exceeds this limit — heavy virtualisation, large datasets or memory-intensive containers — the laptop will throttle to swap and performance will drop sharply. For lighter office tasks the soldered 16GB is ample and the 256GB SSD keeps boot and application launches snappy.

商品問答

Should I pick the 256 GB SSD or look for a larger drive?

The 256 GB solid-state drive holds the operating system and typical business applications with room for documents; if you store large media libraries locally you may want an external drive.

What does the 4.20 GHz turbo speed mean for everyday work?

The i7-8650U can boost to 4.20 GHz for short bursts, speeding up single-threaded tasks like spreadsheet recalculation, while the 1.90 GHz base clock handles sustained loads within the 15 W envelope.

What does the Thunderbolt port actually support on this laptop?

The Thunderbolt port carries data, video and charging through a single USB-C connector, letting you attach docks, external displays or storage without a separate power brick.
