DELL Latitude 7400 laptop 14" i7-8665U 16GB 256GB FHD touchscreen

Business ultraportable with touchscreen

The 2019 Dell Latitude 7400 is a 14.0 inch carbon-fibre laptop built for mobile professionals who need a light device with pen and finger input. It runs Windows 10 Pro on a quad-core Intel Core i7-8665U processor with 16GB of memory and a 256GB SSD. Weighing 1.36kg, it suits consultants and field staff who work away from a desk.

1.9 GHz base clock with 4.80 GHz turbo

The i7-8665U operates at 1.9 GHz under steady load and can reach 4.80 GHz on short bursts across its four cores. This frequency range determines how quickly the system handles spreadsheets, video calls and web-based apps. Buyers who need sustained multi-core throughput for rendering or compilation should consider a higher-wattage workstation instead.

Integrated graphics under continuous use

The integrated graphics chip shares system memory and thermal budget with the CPU, so extended 3D or heavy video workloads will throttle clock speeds to manage heat. The 1920 x 1080 touchscreen remains responsive for typical office tasks, but the platform is not designed for prolonged GPU-intensive sessions. Thunderbolt 3 provides an external GPU option for users who later need more graphics power.
