Professional Workstation for Compute-Intensive

The HP Z4 G4 Mid-Tower Workstation is built for professionals who need single-processor performance with certified reliability. It suits engineers, designers and data scientists running 3D CAD, rendering, simulation or GPU-accelerated applications that demand ISV-certified stability and large memory capacity.

Memory and Graphics Limits

The system ships with 64GB of DDR4 2666 ECC registered memory across four 16GB modules and supports a maximum of 512GB DDR4-2933 ECC SDRAM. The Nvidia Quadro RTX 4000 provides 8GB GDDR6 on a 256-bit bus with three DisplayPort 1.4 outputs and one USB-C graphics connector, limiting display configurations to those four ports.

Tool-Less Access and Power Constraints

A 1000W 80 Plus Gold 90% efficient power supply feeds the platform and the toolless chassis grants straightforward access to PCIe slots and storage bays for upgrades. Builders who need more storage than the single 1TB NVMe drive or who require additional graphics cards must verify slot availability and power budget before expanding.
