Compact AI Workstation

The HP Z2 SFF G1i packs an Intel Core Ultra 5 245K processor and an NVIDIA RTX A400 graphics card into a small-form-factor chassis. It targets professionals who need local AI acceleration and real-time 3D performance without allocating space for a full-size tower. The system ships with Windows 11 Pro, 32 GB of DDR5 memory, and a 1 TB SSD for immediate deployment.

USB and Display Limits

Front I/O provides two USB Type-C ports at 20 Gbps and four USB Type-A ports at 10 Gbps, while the rear adds two more USB Type-A 10 Gbps ports. Video output relies on two DisplayPort 1.4 connectors driven by the discrete GPU. Network connectivity is limited to a single Gigabit Ethernet RJ-45 link, so 10 GbE or wireless options are not available.

Memory and Storage Headroom

The 32 GB DDR5 5600 configuration handles multi-application workloads and moderate dataset caching comfortably. The 1 TB SSD offers sufficient capacity for active projects and the operating system, though large model libraries or raw footage archives will require external expansion. The 4 GB GPU frame buffer restricts scene complexity and texture resolution in heavy rendering tasks.

Questions about this item

Should I pick the 32 GB DDR5 5600 configuration or look for a larger memory option?

The system ships with 32 GB of DDR5 5600 memory; if your workflows need more capacity you can add modules later using the tool-less access.

How does the Intel Core Ultra 5 245K at 4.2 GHz base and 5.2 GHz turbo perform in a compact workstation?

The processor runs at a 4.2 GHz base frequency and can boost to 5.2 GHz, delivering high single-thread speed for CAD and simulation tasks inside the small form factor chassis.

What does the NVIDIA RTX A400 4 GB graphics card provide over the DisplayPort 1.4 outputs?

The RTX A400 supplies 4 GB of dedicated GPU memory and drives up to two DisplayPort 1.4 monitors for 3D design and real-time ray tracing workloads.
