Professional 24-core workstation

The HP Z8 G4 delivers 24 cores across two Xeon Gold 6136 processors running at 3.00GHz, backed by 128GB of DDR4 memory. It targets engineers, designers and data analysts who need reliable multi-threaded throughput for CAD, rendering and large dataset work. A 512GB NVMe drive and NVIDIA Quadro P2000 graphics complete a balanced platform for professional visual and compute tasks.

Sustained multi-threaded throughput

Dual-socket architecture spreads 20 cores per processor across two chips, keeping clock speeds stable during long renders, simulations or compile jobs. The 128GB DDR4 pool reduces paging pressure when multiple heavyweight applications run together. Quadro P2000 hardware acceleration offloads viewport and compute work from the CPUs, preserving system responsiveness for extended sessions.

Rack-ready chassis with internal expansion

Four 3.5-inch drive bays allow local storage growth without external arrays, while front-panel LEDs show power, Ethernet and USB status at a glance. The 55kg frame is built for stationary deployment in studios or server rooms rather than frequent relocation. Windows 11 Pro ships pre-installed so the system is productive immediately after power-on.

Questions about this item

How loud and hot does the dual Xeon Gold 6136 setup get when rendering all day?

The workstation uses two Xeon Gold 6136 processors at 3.00GHz with 20 cores each; sustained loads will raise fan speed and chassis temperature, but exact acoustics and thermals depend on case airflow and room ambient.

Which display cables and monitors do I need to use the Quadro P2000?

The Quadro P2000 provides four DisplayPort outputs; you must supply monitors with DisplayPort inputs and matching cables or active adapters for HDMI, DVI or VGA.

Can I keep my existing DDR4 memory and add it to the 128GB already installed?

The system holds 128GB of DDR4 across its DIMM slots and supports up to 1536GB total; any added modules must be DDR4 ECC RDIMM or LRDIMM matching the installed speed and rank configuration.
