HP Z4 G4 Workstation Xeon W-2235 128GB

The HP Z4 G4 mid-tower workstation pairs an Intel Xeon W-2235 six-core processor at 3.8 GHz with 4.6 GHz turbo. It includes 128 GB DDR4 2933 ECC registered memory in four 32 GB modules. A 2 TB PCIe NVMe SSD and Nvidia Quadro P4000 8 GB GDDR5 graphics with four DisplayPort 1.4 outputs complete the core specification. Windows 11 Pro is pre-installed.

Suits professional CAD and simulation workloads

This system suits engineers and designers running certified ISV applications that require ECC memory and professional GPU drivers. The 1000 W 80 Plus Gold supply and tool-less chassis support expansion. Buyers needing more than 512 GB maximum memory or dual-processor scaling should consider alternative platforms.

Single-processor Xeon W-2235 six-core CPU

The Intel Xeon W-2235 provides six cores at 3.8 GHz base and 4.6 GHz turbo on the LGA 2066 socket. This single-socket configuration defines the workstation's compute ceiling for threaded workloads. Verify that your software licences and parallel scaling match this core count before purchase.

Questions about this item

What is included in the box and what must I buy separately?

The workstation includes the Intel Xeon W-2235 3.8GHz processor, 128GB DDR4 2933 ECC memory, 2TB NVMe SSD, Nvidia Quadro P4000 8GB GDDR5 graphics card with four DisplayPort 1.4 outputs, 1000W 80 Plus Gold power supply, and Windows 11 Pro. A monitor is not included.

Should I choose a different memory or storage capacity for my workflow?

This unit ships with 128GB DDR4 2933 ECC registered memory in a 4x 32GB configuration and a 2TB NVMe SSD. The motherboard supports up to 512GB total memory, so you can add more modules later if your datasets grow beyond the current capacity.

What does the Xeon W-2235 3.8GHz 4.6GHz Turbo 6-core figure mean for real application performance?

The 3.8GHz base clock with 4.6GHz turbo across six cores delivers high single-thread speed for CAD modelling and enough parallel threads for rendering or simulation tasks, while the 128GB ECC memory and Quadro P4000 8GB GDDR5 keep large assemblies and textures in fast memory.
