Professional Workstation for Compute-Intensive

This HP Z4 G4 mid-tower workstation is built for professionals who need reliable single-processor performance. It runs Windows 11 Pro on an Intel Xeon W-2235 3.8GHz 6-core processor with a 4.6GHz turbo frequency. The system targets engineers, designers and analysts running certified ISV applications. It is not suited for buyers who want multi-socket scaling or rack-mount density.

ECC Memory Capacity Decides Fit for Large Datasets

The workstation includes 32GB of DDR4 2933MHz ECC registered memory across four 8GB modules. The platform supports a maximum of 512GB, allowing future expansion for larger simulations. This capacity ceiling is the critical specification for matching the system to workload size. Buyers who need more memory than the platform maximum must choose a different architecture.

Quadro P5000 Drives Multi-Display Visualisation

The included Nvidia Quadro P5000 provides 16GB GDDR5X memory on a 256-bit bus with four DisplayPort 1.4 and one DVI-D DL outputs. This enables direct connection of up to five professional displays without extra adapters. A 1000W 80 Plus Gold power supply supports the GPU and future internal upgrades. Users requiring different display connectors must source their own converters.

Questions about this item

How does the 3.8 GHz base clock with 4.6 GHz turbo translate to actual processing power in this workstation?

The Xeon W-2235 runs at 3.8 GHz base and can boost to 4.6 GHz across its 6 cores, giving strong single-thread speed for CAD and simulation while keeping all cores active under sustained loads.

What does the 256-bit memory interface on the Quadro P5000 mean for GPU-accelerated workloads?

The 256-bit GDDR5X interface feeds the 16 GB frame buffer at high bandwidth, letting the P5000 handle large 3D models, GPU rendering and compute tasks without memory bottlenecks.

Will the mid-tower chassis and 1000 W power supply accommodate the Quadro P5000 and additional drives?

The mid-tower provides full-height PCIe slots and tool-less drive bays; the 1000 W 80 Plus Gold PSU delivers ample headroom for the P5000 plus extra NVMe or SATA storage.
