HP Z2 G4 Workstation

The HP Z2 G4 is a mid-tower desktop workstation built around an Intel Core i7-9700 processor with eight cores and a 4.7 GHz turbo frequency. It ships with 16 GB of DDR4 memory and a 500 GB NVMe solid-state drive. Windows 11 Pro is pre-installed and digitally activated.

LGA 1151 socket compatibility

The system uses an LGA 1151 socket for the i7-9700 CPU, so any processor upgrade must match that socket and the workstation's power envelope. Memory runs at 2666 MHz and the board supports up to 128 GB of DDR4 across its slots. Graphics are provided by the integrated Intel UHD 630 controller with dual DisplayPort outputs.

Integrated connectivity and expansion

A 500 W power supply rated at 90 % efficiency powers the platform and leaves headroom for add-in cards such as professional graphics or additional storage. Onboard networking uses an Intel I219-LM Gigabit Ethernet controller and audio is handled by a Conexant CX20632 5.1 codec. No monitor is included in the package.

Questions about this item

How does the 3.0 GHz base and 4.7 GHz turbo on the i7-9700 translate to everyday workloads?

The 8-core processor runs at 3.0 GHz for sustained tasks and can boost to 4.7 GHz on lighter threads, giving strong single-thread responsiveness and solid multi-thread throughput for CAD, rendering or data analysis.

What does the integrated Intel HD Graphics 630 limit in practice?

The Intel UHD 630 drives two DisplayPort monitors for office and 2D work, but lacks dedicated video memory and professional driver certification, so it is not suited for GPU-accelerated 3D or compute workloads.

What physical space and power does the 500 GB NVMe drive require inside this mid-tower?

The drive occupies one M.2 slot on the motherboard and draws power directly from the board; the 500 W 90 % efficient supply and mid-tower chassis leave ample room for additional storage or a full-length graphics card.
