Small Form Factor Desktop

The Dell Pro Slim QCS1250 is a small form factor desktop built around an Intel Core i7-14700K 20-core processor with 33MB cache and turbo speeds up to 5.6 GHz. It ships with 16GB DDR5 memory, a 4TB NVMe SSD and Windows 11 Pro, plus a wired keyboard and mouse. This configuration targets business and education users who need a compact, ready-to-deploy workstation.

20-Core Processor with 5.6 GHz Turbo

The single specification that decides fit is the Intel Core i7-14700K, a 20-core CPU (8 performance plus 12 efficient cores) capable of 5.6 GHz maximum turbo frequency and 33MB smart cache. Buyers who need more cores, higher base clocks or a discrete graphics card for compute or rendering workloads should look elsewhere.

Sustained Load Behaviour

Under continuous multi-threaded load the 20-core design distributes work across performance and efficient cores while the integrated Intel UHD Graphics 770 handles display output via HDMI 2.1 and DisplayPort 1.4a. The small 3.74-inch wide chassis limits thermal headroom, so prolonged all-core turbo will settle at lower frequencies than the 5.6 GHz peak.

Questions about this item

How does the 5.6 GHz boost clock of the Core i7-14700K behave inside this small-form-factor chassis?

The 20-core processor reaches 5.6 GHz on Turbo Boost when thermal headroom allows; the compact 95 mm-wide case relies on Dell's internal airflow design to sustain high frequencies during burst workloads.

What display outputs does the integrated Intel UHD Graphics 770 provide and what resolutions do they support?

One HDMI 2.1 and one DisplayPort 1.4a port drive up to two monitors; both connectors support 4K at 60 Hz and HDR content from the integrated graphics engine.

Will the 303.5 mm height and 95 mm width fit on a standard desk shelf or VESA mount?

The chassis measures 11.95 in tall by 3.74 in wide by 11.54 in deep and weighs 8.61 lb; it sits upright on a desk and Dell offers an optional VESA bracket for behind-monitor mounting.
