Dell Pro Slim QCS1250 SFF Business Desktop

The Dell Pro Slim QCS1250 is a small form factor desktop built for business and education environments. It ships with Windows 11 Pro and includes a wired keyboard and mouse. The Intel Core Ultra 9 285K processor delivers 24 cores and a 36MB cache. Integrated Intel UHD Graphics 770 drives up to two external displays.

Suited for office productivity

This system suits organisations that need a compact, managed PC with a modern 24-core processor and fast NVMe storage. Buyers who require a discrete graphics card for 3D rendering or GPU compute should look elsewhere. The small chassis limits internal expansion to the existing M.2 slot. Users needing more than 16GB of memory or additional drive bays will need a larger platform.

24-core Intel Core Ultra 9 285K processor

The single specification that determines fit is the 24-core Intel Core Ultra 9 285K with a 5.7GHz maximum turbo frequency. It provides high multi-thread throughput for demanding business workloads and includes a 13 TOPS NPU for AI acceleration. If the workload is lightly threaded or budget-sensitive, a lower-core-count processor may be more appropriate.
