Ultra-small desktop for office work

The DELL OptiPlex 3090 UFF is an ultra-small form factor desktop designed for business environments where desk space is limited. It ships with Windows 11 Pro installed and includes integrated Wi-Fi and Bluetooth 5 connectivity. This configuration suits general productivity, web browsing and video conferencing without a discrete graphics card.

Quad-core i5-1145G7 processor

The system uses an Intel Core i5-1145G7 quad-core processor with a maximum turbo frequency of 4.40 GHz and 8 MB cache. Intel UHD Graphics handles display output through a DisplayPort 1.4 HBR2 port. Performance scales with the 16 GB DDR4 3200 MHz memory module installed in a single slot.

16 GB DDR4 and 256 GB NVMe

Memory capacity is 16 GB DDR4 in a 1×16 GB layout, leaving one UDIMM slot open for expansion up to the platform maximum. The 256 GB PCIe M.2 NVMe Class 35 drive provides fast boot and application load times. An internal M.2 2230 slot and a SATA 3.0 FFC connector allow additional storage, while the compact 96.10 mm width chassis limits further internal upgrades.

Questions about this item

How does the i5-1145G7's 4.40 GHz boost clock behave under sustained loads in this ultra-small chassis?

The 4.40 GHz turbo is available on single cores for short bursts; thermal limits in the 256.20 mm tall case mean all-core speeds settle lower during long workloads.

What display bandwidth does the DisplayPort 1.4 HBR2 port actually provide?

The port supports HBR2 link rates, capping usable bandwidth at the HBR2 level rather than full DisplayPort 1.4 HBR3 throughput.

Will a standard 2.5-inch SATA drive fit alongside the existing M.2 SSD?

The chassis includes one SATA 3.0 FFC connector for a 2.5-inch drive, but physical mounting space must be verified inside the ultra-small form factor.
