Dell Latitude 5520 laptop i5 1145G7 8GB 256GB NVMe 15.6" FHD

Dell Latitude 5520 for professionals

The Dell Latitude 5520 is a 15.6 inch business laptop built around an Intel Core i5 1145G7 processor with four cores and eight threads. It ships with 8GB of DDR4 memory and a 256GB NVMe SSD running Windows 10 Pro. The chassis includes HDMI, two Thunderbolt 3 ports, Gigabit Ethernet and a microSD card reader. This configuration targets office workers and mobile professionals who need a reliable daily driver with modern connectivity.

Sustained workload behaviour

Under continuous load the quad-core Tiger Lake CPU maintains its 2.6 GHz base frequency across all four cores while the integrated Intel Iris Xe graphics share system memory. The 8GB DDR4 capacity and single NVMe drive define the practical ceiling for simultaneous applications and large dataset access. Thermal management in the 15.6 inch body allows the processor to hold performance longer than thinner ultraportables, though memory bandwidth remains the limiting factor for heavy multitasking.

Deciding specification: 8GB soldered memory

The 8GB DDR4 configuration is the single figure that determines suitability; the platform supports up to 32GB but the installed amount is fixed at purchase. Buyers who need more memory for virtual machines, large spreadsheets or creative suites must choose a different unit because this laptop cannot be upgraded after sale. The 256GB NVMe drive and FHD non-touch display are secondary considerations compared to this memory constraint.
