HP Z4 G4 Workstation Xeon W-2235 16GB DDR4 1TB NVMe Quadro P4000 8GB Win 11 Pro

Professional Workstation for Compute-Intensive

The HP Z4 G4 is a mid-tower workstation built around an Intel Xeon W-2235 6-core processor running at 3.8 GHz with a 4.6 GHz turbo frequency. It ships with 16 GB of DDR4 2933 ECC registered memory in a dual-channel configuration. A 1 TB PCIe NVMe SSD provides the primary boot and project storage. An NVIDIA Quadro P4000 graphics card with 8 GB GDDR5 memory and four DisplayPort 1.4 outputs drives professional visualisation tasks. The system includes a 1000 W 80 Plus Gold power supply and Windows 11 Pro.

Upgrading from Entry-Level or Older Xeon Platforms

This configuration replaces systems limited to non-ECC consumer memory or lower-core-count CPUs that bottleneck rendering and simulation workloads. The jump is worth it when your applications demand registered ECC memory for data integrity and the 256-bit memory interface of the Quadro P4000 for large model manipulation. The LGA 2066 platform supports up to 512 GB of DDR4 2933, allowing substantial memory expansion as dataset sizes grow. The 1000 W power supply provides headroom for adding high-power GPUs or additional storage controllers.

Limits of the LGA 2066 Platform and Quadro P4000

The platform uses the LGA 2066 socket and DDR4 2933 memory standard, capping memory speed at that frequency regardless of faster module ratings. The Quadro P4000 connects via a PCIe slot and offers four DisplayPort 1.4 outputs; it does not support newer display signalling standards beyond 1.4. Storage expansion relies on available M.2 slots for NVMe drives and internal bays for SATA devices, but the total number of lanes and ports is defined by the chipset. The 1000 W power supply sets the total power budget for all installed components.
