HP Z4 G4 Business Desktop Xeon W-2225 64GB 500GB NVMe Quadro RTX 4000

Mid-tower workstation for professional workflows

This HP Z4 G4 mid-tower workstation targets engineers, designers and analysts who need certified single-processor performance. An Intel Xeon W-2225 4-core CPU runs at 4.1 GHz with a 4.6 GHz turbo frequency. 64 GB of DDR4 2933 ECC registered memory and a 500 GB NVMe SSD provide a responsive platform for large datasets. Nvidia Quadro RTX 4000 graphics with 8 GB GDDR6 drive 3D CAD, rendering and GPU-accelerated applications. Windows 11 Pro is pre-installed.

Tool-less access and standard power connectors

The chassis features toolless entry for memory, storage and expansion cards. Four DIMM slots are populated with 16 GB modules each, leaving room to reach the 512 GB maximum. Multiple internal bays and M.2 slots accept SATA and PCIe NVMe drives without adapters. A 1000 W 80 Plus Gold 90% efficient supply uses standard ATX cables; no proprietary pin-outs complicate GPU upgrades. Integrated Gigabit Ethernet and high-definition audio require no extra cards.

64 GB ECC memory and 8 GB GDDR6 frame buffer

The 64 GB DDR4 2933 ECC configuration handles complex simulations and multi-application workloads with headroom to scale to 512 GB. The 500 GB NVMe boot drive delivers fast project loading; additional SATA or NVMe drives can be added for capacity. Quadro RTX 4000 8 GB GDDR6 256-bit memory drives up to four displays via three DP 1.4 and one USB-C connector. The single-socket Xeon W-2225 limits core count to four, so heavily threaded render farms or massive in-memory databases will need a dual-socket platform.
