Business SFF desktop with i7-14700

The HP ProDesk 400 G9 is a small-form-factor business desktop built around an Intel Core i7-14700 processor with 20 cores and 28 threads. It ships with Windows 11 Pro, 64GB of DDR5 4800 memory in a 32GB x 2 configuration, and a 1TB SSD. Intel UHD Graphics 770 drives up to three independent displays via rear DisplayPort and HDMI 1.4. A wired keyboard and mouse combo plus Wi-Fi 5 are included for immediate deployment.

Who this suits and who should look elsewhere

This system fits offices that need strong multi-threaded performance for spreadsheets, code compilation, or financial modelling in a compact chassis. It is not for buyers who require discrete graphics acceleration for 3D rendering, CAD, or gaming workloads. It is not for teams needing tool-less internal expansion bays or support for additional high-wattage add-in cards beyond the SFF power envelope.

Deciding specification: 64GB DDR5 4800 soldered

The memory is populated as two 32GB DDR5 4800 modules, filling both DIMM slots and reaching the platform maximum of 64GB. No further RAM upgrades are possible without replacing the existing sticks. Verify that this capacity ceiling matches your workload before purchase.
