HP Z4 G4 Mid-Tower Workstation Xeon W-2235 3.8GHz 64GB DDR4 2TB NVMe Quadro P4000 8GB Windows 11 Pro

Professional workstation for compute-intensive

The HP Z4 G4 mid-tower workstation is built for professionals who need single-processor performance in demanding applications. An Intel Xeon W-2235 six-core processor runs at 3.8GHz with a 4.6GHz turbo frequency, while 64GB of DDR4 2933 ECC registered memory provides reliable capacity for large datasets. A 2TB PCIe NVMe drive supplies fast system storage and the NVIDIA Quadro P4000 8GB GDDR5 graphics card with 256-bit bus drives 3D CAD and visualization tasks. Windows 11 Pro is pre-installed for immediate deployment.

Tool-free chassis with professional connectivity

The mid-tower form factor uses a 1000W 80 Plus Gold 90% efficient power supply and offers tool-free access to internal components for easier upgrades and maintenance. Four DisplayPort 1.4 outputs on the Quadro P4000 support multi-monitor configurations without adapters. Integrated Gigabit Ethernet and high-definition audio handle network and sound requirements. The LGA 2066 socket and four populated DIMM slots leave room for memory expansion within the 512GB maximum supported by the platform.

Platform limits defined by memory ceiling

Maximum memory capacity stops at 512GB DDR4 2933 ECC on Xeon configurations, so workloads exceeding that ceiling need a different platform. The single-processor design cannot scale to dual-socket throughput for heavily parallel jobs. PCIe expansion slots provide add-in card flexibility, but total lane count and bandwidth are constrained by the single CPU. Storage expansion relies on available M.2 and internal bays, and the 1000W power supply sets the upper bound for combined component draw.
