Use Cases & Applications

Office Administration & Business Workstations The 14-core processor with 24MB cache and 512GB NVMe SSD handles intensive multitasking and quick data access across email, spreadsheets, ERP systems, and video conferencing — comfortably managing multiple open applications without slowdown. Connection

Software Development on Linux The Ubuntu 24.04 LTS pre-installation means developers avoid OS setup time and dive straight into coding environments, terminals, and package managers. The free PCIe x16 slot and second RAM slot leave clear upgrade paths as project demands scale.

IT Lab & Enterprise Deployment Security features including TPM 2.0 and theft/intrusion protection give IT administrators confidence across multi-unit deployments. Dell Command Monitor also supports remote asset management across a network for centralised oversight. CDW

Light Data Analysis & Scripting The 13 TOPS NPU accelerates AI-assisted tasks — running inference models, automation scripts, and data processing pipelines locally without offloading to cloud compute, keeping sensitive business data on-premise.

Upgrading Legacy Office Hardware At 154mm wide, the QCT1250 fits under desks and on shelves where older tower units currently sit. The VGA optional expansion module makes it compatible with existing monitors, avoiding the cost of display replacements during a hardware refresh.

How Does the Core Ultra 5 235 Compare to the Core Ultra 7 265?

Both processors share the same 13 TOPS NPU and fit the same QCT1250 chassis. However, the Ultra 7 265 adds 6 more cores (20 vs 14), a higher max turbo speed (5.3GHz vs 5.0GHz), and handles heavier parallel workloads more comfortably. For standard business tasks — document work, web applications, video calls, and moderate development — the Ultra 5 235 performs the same day-to-day duties at a lower cost point. Teams running large compilation jobs, virtual machines, or heavy data pipelines will benefit from the step up to the Ultra 7 configuration.

Frequently Asked Questions

Does the Dell Pro Tower QCT1250 (Ultra 5 235) support Windows? Yes. While this configuration ships with Ubuntu Linux 24.04 LTS, the hardware supports Windows 11 Pro and Windows 11 Pro National Education. Users can install a licensed copy of Windows independently.

Can you upgrade the RAM in this configuration? Yes. The base 8GB runs as a single UDIMM in one slot, leaving the second slot free. You can upgrade to 16GB, 32GB, or up to 64GB of DDR5 by adding a second compatible module.

Does it include Wi-Fi? This configuration ships with no wireless LAN card installed. However, the board includes a dedicated M.2 2230 slot that accepts an optional Intel Wi-Fi 6E AX211 card with Bluetooth 5.3. Icekh

Can you add a dedicated graphics card later? Yes. The full-height PCIe x16 slot accepts a discrete GPU. The 180W Bronze power supply limits compatible card options — check GPU power draw before purchasing.

Does it include a keyboard and mouse? This configuration includes a Dell Wired Keyboard KB216 and Dell USB Optical Mouse MS116. Icekh
