15.6" FHD touchscreen laptop with 10-core i7

The Dell Inspiron 3520 15 combines a 15.6-inch Full HD touchscreen with an Intel Core i7-1255U 10-core processor running at a 1.2 GHz base and 4.7 GHz turbo. Thirty-two gigabytes of DDR4 memory and a 2 TB PCIe SSD provide ample capacity for multitasking and large files. Windows 11 Pro ships pre-installed.

Ports and connectivity for daily workflows

Two USB 3.2 Type-A ports, one USB 2.0 Type-A port, an HDMI output and a multi-format SD card reader handle peripherals and external displays. Integrated Wi-Fi and Bluetooth cover wireless networking and accessories. The chassis measures 14.11 by 9.27 by 0.83 inches and weighs 3.65 pounds, leaving room in a bag for other gear.

Sustained performance with integrated graphics

The Intel Iris Xe graphics share system memory, so extended 3D or compute loads draw from the same 32 GB pool used by applications. Thermal limits in the slim 0.83-inch profile mean clock speeds will settle below the 4.7 GHz maximum during long sessions. Buyers who need discrete GPU power or a backlit keyboard should look elsewhere.
