Dell XPS 14 DA14250 laptop Ultra 7-255H 16GB LPDDR5X 4TB SSD 14.5 OLED 3.2K touch

Dell XPS 14 DA14250 Ultra 7 laptop

The Dell XPS 14 DA14250 is a 14.5-inch laptop built around the Intel Core Ultra 7-255H processor with 16 cores and a 5.1 GHz turbo frequency. It ships with 16GB of onboard LPDDR5X memory and a 4TB PCIe NVMe SSD. The 3.2K OLED touchscreen runs at 120Hz and covers a 16:10 aspect ratio. Windows 11 Home is pre-installed.

Sustained workload behaviour

The 15th Gen Ultra 7-255H uses six performance cores and ten efficient cores to balance throughput when the system runs hot. Integrated Intel Arc graphics share the same thermal envelope as the CPU, so extended compute or media tasks draw from a single cooling solution. Thunderbolt 4 ports maintain bandwidth for external storage or docks during long sessions. The 70 WHr battery supplies energy without a discrete GPU penalty.

Thermals noise and power

A 60W USB-C adapter charges the 6-cell 70 WHr pack while the laptop operates. The graphite chassis measures 0.9 inches at its thickest point, limiting fan volume under load. Surface temperatures stay manageable during typical productivity work because the Arc graphics are integrated rather than discrete. Acoustic output remains low enough for quiet rooms.
