HP ProDesk 400 G5 SFF desktop

The HP ProDesk 400 G5 SFF desktop is a compact business PC built around a 6-core Intel Core i5-9700T processor running at 2.2GHz. It ships with 16GB of memory, a 512GB SSD and Windows 11 Pro pre-installed. Integrated Intel UHD Graphics 630 drives the included 22-inch LCD and a USB Wi-Fi adapter provides wireless connectivity.

Sustained workload behaviour

The 6-core CPU maintains its 2.2GHz base frequency across extended tasks such as large spreadsheet calculations or background indexing. With only 16GB of RAM installed out of a 32GB maximum, memory pressure can appear when many browser tabs and office apps run together. The small form factor chassis limits airflow, so prolonged heavy loads will raise internal temperatures and may trigger thermal throttling.

Integrated graphics and storage limits

Intel UHD Graphics 630 relies on system memory and suits general desktop work, video playback and basic multi-monitor use; it is not designed for 3D rendering or modern gaming workloads. The single 512GB SSD offers fast boot and application launch but leaves no internal bay for a second drive, so capacity expansion requires external USB storage. The USB Wi-Fi adapter delivers convenient wireless access but lacks the throughput and latency consistency of a wired Ethernet connection.
