DELL Latitude 7400 laptop 14" i7-8665U 16GB 512GB

Business-ready 14-inch laptop

The Dell Latitude 7400 is a 14-inch business laptop built around an 8th Generation Intel Core i7-8665U processor with 16GB of DDR4 memory and a 512GB solid-state drive. It ships with Windows 10 Professional 64-bit and a 1920 x 1080 non-touch anti-glare display. Integrated Intel UHD Graphics handle everyday visual tasks. The chassis includes a backlit keyboard, RGB IR camera and a 60WHr 4-cell battery.

Sustained workload behaviour

The quad-core i7-8665U runs at a 1.9GHz base frequency and can reach 4.80GHz turbo speeds with 8MB of SmartCache for burst performance. Under continuous load the 65W barrel adapter and 60WHr battery govern thermal limits, so extended compile or render sessions will settle at lower clocks than short bursts. DDR4 1866 memory bandwidth and integrated graphics share system RAM, which can become a bottleneck during heavy multitasking.

Deciding specification

The single specification that decides fit is the Thunderbolt 3 port with DisplayPort and Power Delivery support, which enables single-cable docking, external GPU enclosures and high-speed storage. Buyers who need more than two USB Type-A ports, a full-size SD reader or discrete graphics for 3D work should look elsewhere. The 512GB SSD capacity and 16GB soldered memory are fixed at purchase.
