DELL DC15250 laptop i7-1355U 32GB 1TB 15.6" FHD 120Hz

15.6" 120Hz laptop for business multitasking

This 15.6 inch laptop pairs a 10-core Intel Core i7-1355U with 32GB of DDR4 4266 memory and a 1TB SSD. The 1920 x 1080 120Hz FHD panel delivers smooth motion for spreadsheet work and video calls. Integrated Intel UHD Graphics handles everyday visual tasks without a discrete GPU. It ships with Windows 11 Pro and includes Wi-Fi 6 plus Bluetooth for modern wireless connectivity.

Sustained workload behaviour

The 10-core processor reaches up to 5.00 GHz boost clocks, but the UHD graphics share system memory and thermal headroom with the CPU. During long compile jobs or heavy browser sessions the chassis warms to 4.28 lbs of aluminium and plastic, so clock speeds may settle below the peak figure. The 120Hz display stays responsive, yet frame pacing in 3D apps will remain limited by the integrated graphics architecture rather than the screen refresh rate.

Check ports power and memory before ordering

Verify that your peripherals work with one HDMI 1.4, one USB 3.2 Gen 1 Type-C with full function, one USB 3.2 Gen 1 Type-A and one USB 2.0 port. The SD card reader accepts standard formats but not UHS-II speeds. RAM is soldered DDR4 4266 so capacity cannot be increased after purchase. The 1TB SSD is the only internal storage slot, and the 1.20 GHz base clock means single-thread bursts rely heavily on thermal boost duration.
