DELL Inspiron 3520 15 laptop i7-1255U 10-core 16GB 2TB 15.6 FHD Touchscreen

Ready-to-work laptop for office and study

The Dell Inspiron 3520 15 arrives with Windows 11 Pro installed and a 10-core Intel Core i7-1255U processor. Sixteen gigabytes of DDR4 memory and a 2 TB PCIe solid-state drive handle documents, spreadsheets and web apps without waiting. The 15.6-inch FHD touchscreen adds direct interaction for presentations or note-taking.

10-core processor with 4.7 GHz peak

The i7-1255U runs at a 1.2 GHz base and can reach 4.7 GHz maximum turbo frequency across its 10 cores and 12 threads. Integrated Intel Iris Xe graphics share system memory, so performance scales with the 16 GB DDR4 capacity. This CPU and graphics combination determines whether the laptop suits your daily workload.

Sustained performance within a slim chassis

The 14.11 x 9.27 x 0.83-inch body weighs 3.65 pounds and relies on passive and fan-assisted cooling for the 15-watt processor. Under long compile, render or video-export sessions the chip will settle to a steady clock below the 4.7 GHz peak to manage thermals. Buyers who need continuous maximum turbo or discrete-graphics power should consider a larger workstation-class machine.
