Professional Mid-Tower Workstation

This HP Z4 G4 is a new mid-tower business desktop built around an Intel Xeon W-2223 3.6GHz 4-core processor. It ships with 64GB DDR4 2666MHz ECC registered memory, a 500GB NVMe SSD and an Nvidia Quadro RTX 5000 16GB GDDR6 graphics card. Windows 11 Pro is pre-installed and activated.

Ideal for Certified Professional Apps

The configuration suits engineers and designers running ISV-certified CAD, rendering or simulation workloads that rely on professional GPU drivers and ECC memory stability. Buyers who need more than 512GB maximum memory capacity or require multi-processor scaling should evaluate dual-socket platforms instead.

16GB GDDR6 Professional Graphics

The Quadro RTX 5000 provides 16GB GDDR6 memory on a 256-bit bus with four DisplayPort 1.4 outputs and VirtualLink. This VRAM capacity is the decisive factor for handling large 3D models, high-resolution textures and GPU-accelerated compute datasets without paging to system memory.

Questions about this item

How much RAM can the Xeon W-2223 configuration address before the memory controller hits its ceiling?

The Xeon W-2223 platform supports up to 512 GB of DDR4 2666 ECC registered memory across eight DIMM slots.

What thermal load does the 1000 W 80 Plus Gold supply sustain when the RTX 5000 and Xeon run flat-out?

The 1000 W 80 Plus Gold unit delivers up to 90 % efficiency at full load, keeping waste heat low during continuous GPU and CPU compute.

Which display connectors must my monitors provide for the Quadro RTX 5000 to drive them?

The RTX 5000 offers four DisplayPort 1.4 outputs and one VirtualLink port, so each monitor needs a DisplayPort 1.4 or USB-C VirtualLink input.
