Tower desktop with 24-core Core Ultra 9 285K

The DELL ECT1250 is a new tower system built around an Intel Core Ultra 9 285K processor with 24 cores and 36MB cache. It ships with 48GB of DDR5 5600 MHz memory and a 512GB NVMe SSD. Windows 11 Home is pre-installed and an NVIDIA GeForce RTX 3050 6GB GDDR6 card handles graphics output.

Suits AI-assisted office work

This configuration serves professionals who need high thread counts for local AI inference via the integrated NPU and smooth multitasking across several monitors. The single 512GB drive and mid-range GPU mean builders who need large local datasets or high-frame-rate 3D rendering should look at something else.

48GB DDR5 5600 MHz memory soldered capacity

The 48GB DDR5 5600 MHz kit defines the memory ceiling for this platform. Buyers whose workloads exceed this capacity cannot expand it later and must choose a different system.
