HP Z4 G4 Workstation Xeon W-2235 3.8GHz 6 Core 16GB DDR4 500GB NVMe Quadro P5000 16GB Windows 11 Pro

Xeon W-2235 6-Core Workstation

The HP Z4 G4 is a mid-tower workstation built around an Intel Xeon W-2235 processor with six cores running at 3.8GHz and a 4.6GHz turbo frequency. It targets professionals who need certified single-processor performance for compute-intensive applications such as 3D CAD, rendering and complex simulations. The system ships with Windows 11 Pro and includes an NVIDIA Quadro P5000 graphics adapter with 16GB GDDR5X memory for GPU-accelerated workloads.

16GB DDR4 and 500GB NVMe Capacity

The workstation arrives with 16GB of DDR4 2933 ECC registered memory in a dual-channel configuration and a 500GB M.2 NVMe solid-state drive for fast system responsiveness. Memory capacity can be expanded to 512GB on Xeon configurations, providing headroom for large datasets and heavy multitasking. Storage flexibility comes from multiple internal bays and additional M.2 slots that accept combinations of SATA and PCIe NVMe drives. Buyers who need more than 16GB of memory or larger boot storage out of the box will have to add modules or drives themselves.

LGA 2066 Platform and PCIe Expansion

The Xeon W-2235 uses the LGA 2066 socket and supports DDR4 2933 speeds, defining the platform's memory and CPU upgrade path. Graphics output is delivered through four DisplayPort 1.4 connectors and one dual-link DVI-D port on the Quadro P5000, which uses a 256-bit memory interface. The chassis provides multiple PCIe slots for add-in cards and toolless access for maintenance. A 1000W 80 Plus Gold power supply rated at 90% efficiency powers the configuration. Builders who require a different socket or chipset cannot use this platform.
