DELL Latitude 3520 15.6" 16GB 256GB i5-1135G7 laptop

Business notebook with 15.6" display

The Latitude 3520 is a 15.6-inch Windows 11 Pro laptop built for office work and mobile professionals. It ships with a quad-core Intel Core i5-1135G7 processor running at 2.4 GHz, 16 GB of DDR4 memory and a 256 GB NVMe SSD. The TN panel offers a 1366 x 768 resolution without touch input, while integrated Intel Iris Xe Graphics handles everyday visual tasks.

Upgrade from 8 GB or hard-drive systems

Moving from an 8 GB configuration or a mechanical drive to this 16 GB and 256 GB NVMe combination removes the bottlenecks that slow multitasking and boot times. The two memory slots support up to 32 GB total, so the jump is worth it when current RAM is saturated or storage feels sluggish. Buyers who need more storage or a higher-resolution screen should look elsewhere.

Sustained workloads on integrated graphics

Under continuous load the integrated Iris Xe GPU shares system memory and thermal budget with the CPU, so extended rendering or heavy spreadsheet calculation will throttle clock speeds to manage heat. The 6 MB L3 cache and quad-core design keep background tasks responsive, but the platform is not sized for prolonged GPU-intensive sessions. Gigabit LAN and 802.11 wireless provide stable connectivity during long work periods.
