Professional workstation for compute-intensive

The HP Z4 G4 Mid-Tower workstation targets engineers, designers and analysts who need certified single-processor performance. An Intel Xeon W-2225 four-core processor runs at 4.1 GHz with a 4.6 GHz turbo frequency. Sixteen gigabytes of DDR4 2933 ECC registered memory and a 500 GB NVMe SSD provide a responsive foundation for large datasets and complex simulations.

PCIe expansion limits and graphics connectivity

The mid-tower chassis provides multiple PCIe slots for add-in cards while the Nvidia Quadro RTX 5000 occupies one slot with its 256-bit GDDR6 frame buffer. Display output is handled through four DisplayPort 1.4 connectors and a VirtualLink port. Integrated Gigabit Ethernet and high-definition audio handle baseline networking and sound without additional hardware.

Memory headroom and power reserve

The platform supports up to 512 GB of DDR4 2933 ECC memory, leaving substantial room beyond the factory 16 GB configuration. A 1000 W 80 Plus Gold power supply rated at 90 percent efficiency delivers ample reserve for the RTX 5000 and future storage or accelerator upgrades. Windows 11 Pro 64-bit is pre-installed and digitally activated.

Questions about this item

Should I pick the 500 GB NVMe drive or add a larger SATA SSD for my project files?

The 500 GB PCIe NVMe SSD handles the OS and active projects quickly, while the chassis has spare bays and M.2 slots for additional SATA or NVMe drives if you need more capacity.

What does the Xeon W-2225 4.1 GHz base clock mean for sustained compile jobs?

The four-core Xeon W-2225 runs at 4.1 GHz base and can boost to 4.6 GHz, giving strong single-thread speed for compile workloads while the 16 GB DDR4 2933 ECC memory keeps data integrity high.

How many DisplayPort 1.4 monitors can the Quadro RTX 5000 drive at once?

The card provides four DisplayPort 1.4 outputs plus a VirtualLink connector, so up to four DP 1.4 displays can be attached directly.
