Workstation for professional workloads

The HP Z2 G4 Mid-Tower is a new business workstation built around an Intel Core i5-9500 six-core processor with a 3.0 GHz base and 4.4 GHz turbo frequency. It ships with 16 GB of DDR4 2666 memory in a dual-channel configuration and a 1 TB NVMe SSD. Integrated Intel UHD Graphics 630 provides dual DisplayPort video output. Windows 11 Pro 64-bit is pre-installed and digitally activated.

Six-core CPU with 4.4 GHz turbo

The Intel Core i5-9500 delivers six cores without hyper-threading, reaching 4.4 GHz on turbo for single-threaded bursts. This clock speed is the primary indicator of how the system handles CAD, simulation pre-processing and compile workloads. The LGA 1151 socket and 128 GB maximum memory ceiling define the upgrade envelope for future expansion.

Suited for entry ISV and office deployments

This configuration fits buyers who need certified ISV stability, ECC-free memory economics and a 500 W 90 % efficient power supply in a mid-tower chassis. It does not meet the needs of users who require discrete professional graphics, hardware ECC memory support or a higher core-count processor for sustained multi-threaded rendering.

Questions about this item

What does the 4.4 GHz turbo frequency mean for everyday workloads?

The i5-9500 can boost up to 4.4 GHz on a single core when thermal headroom allows, speeding up bursty tasks like app launches or spreadsheet recalculations.

How does the integrated Intel UHD Graphics 630 limit display options?

It provides two DisplayPort outputs and supports dual monitors at typical business resolutions, but lacks dedicated video memory for 3D workloads.

What physical space and power does the mid-tower chassis require for upgrades?

The 500 W 90 % efficient supply and standard ATX mid-tower layout accept full-height PCIe cards and additional 3.5″ or 2.5″ drives.
