DELL 15 laptop i7-1355U 16GB 512GB 15.6 FHD Touch

15.6-inch touchscreen business laptop

The Dell 15 is a new Windows 11 laptop built around a 10-core Intel Core i7-1355U processor with 16 GB of DDR4 memory and a 512 GB PCIe SSD. Its 15.6-inch FHD touchscreen and integrated Intel Iris Xe graphics suit office work, web browsing and light content creation. The chassis measures 14.11 by 9.28 by 0.75 inches and weighs 4.19 lbs in black.

Sustained-load behaviour with U-series silicon

The 15-watt U-series chip reaches a 5.0 GHz turbo frequency for short bursts but settles to its 1.00 GHz base under continuous multi-threaded loads such as large compiles or video exports. Intel Iris Xe graphics share system memory, so extended 3D or compute tasks will throttle once the thermal solution saturates. Fan noise rises noticeably during prolonged heavy workloads.

16 GB soldered memory decides upgrade path

The 16 GB of DDR4 is not user-expandable, so buyers who need more than 16 GB for virtual machines, heavy multitasking or large datasets must choose a different model. The 512 GB PCIe SSD can be replaced, but the memory ceiling is fixed at purchase.
