Pro Max 14 Copilot+ PC

The Dell Pro Max 14 MC14250 is a 14-inch Copilot+ PC built around the Intel Core Ultra 7 255H processor with 16 cores and Intel AI Boost NPU. It ships with Windows 11 Pro, 16 GB of LPDDR5X memory and a 512 GB M.2 SSD. The touchscreen panel supports pen and finger input for modern workflows.

Sustained load with Arc Pro 140T

The Intel Arc Pro 140T graphics run on shared LPDDR5X system memory rather than discrete VRAM. Under prolonged workloads the integrated GPU and NPU share the same thermal envelope as the 16-core CPU, so performance scales with the chassis cooling capacity over time. The 60 Hz Full HD Plus panel caps visible frame rates at 60 regardless of render speed.

Build, connectivity and daily use

The anti-glare LCD delivers 300 nits brightness and 100% sRGB coverage for colour-accurate work in varied lighting. A Gigabit Ethernet RJ-45 port and Wi-Fi 7 (IEEE 802.11be) provide wired and wireless network options. Memory uses a single LPCAMM module with no free slots, while the M.2 SSD bay supports future storage expansion up to the platform limit of 64 GB total memory.
