DELL Latitude 7400 laptop i7-8650U 16GB 1TB touchscreen

Business ultrabook with 14-inch touchscreen

The Dell Latitude 7400 is a thin-and-light business laptop built around an 8th Gen Intel Core i7-8650U quad-core processor. It ships with Windows 10 Pro, 16 GB of DDR4 2133 memory in a dual-channel 8 GB x 2 configuration, and a 1 TB M.2 2242 SSD. The 14.0-inch 1920 x 1080 touchscreen and integrated Intel UHD Graphics suit mobile professionals who need pen or finger input.

Sustained workload behaviour

Under continuous load the quad-core CPU and integrated graphics share the same thermal envelope, so extended compile jobs or heavy spreadsheet calculation will throttle clock speeds after the initial burst. The 65-watt AC adapter powers the system and charges the battery simultaneously, but prolonged maximum performance cannot be maintained without temperature rise. Both memory slots are occupied, so multitasking headroom is fixed at 16 GB unless modules are replaced.

Compatibility checks before ordering

Verify that your docking station or monitor supports the single Thunderbolt port with DisplayPort alt-mode for external video, as the unit lacks a second Thunderbolt connection. Confirm that any replacement memory uses DDR4 2133 SO-DIMMs, because the board does not accept other DDR generations. The M.2 2242 slot limits future storage upgrades to that form factor, so larger 2280 drives will not fit.
