HP Z2 G4 Mid-Tower desktop PC i5-9500 64GB 2TB NVMe Quadro P4000 8GB Windows 11 Pro

HP Z2 G4 workstation for professional workloads

The HP Z2 G4 mid-tower desktop delivers workstation-class performance for engineering, design and content-creation tasks. It combines a six-core Intel Core i5-9500 processor with 64 GB of DDR4 2666 memory and a 2 TB NVMe solid-state drive. An NVIDIA Quadro P4000 graphics card with 8 GB GDDR5 memory drives up to four DisplayPort 1.4 monitors for multi-display workflows. Windows 11 Pro is pre-installed and digitally activated.

Sustained compute and graphics throughput

The six-core CPU operates at a 3.0 GHz base frequency and can reach 4.4 GHz turbo when thermal headroom allows, maintaining higher clocks during extended renders or simulations. Four 16 GB unbuffered DDR4 modules run at 2666 MHz to feed both processor and GPU without bottlenecks. The Quadro P4000 uses a 256-bit memory interface to keep large datasets moving through its 8 GB frame buffer during long compute sessions. The 2 TB PCIe NVMe drive provides consistent read and write speeds for project files and scratch space.

Thermal management and power efficiency

A 500 W power supply rated at 90 percent efficiency converts mains power with minimal waste heat under typical loads. The mid-tower chassis directs airflow across the CPU, GPU and memory to keep temperatures stable during prolonged work periods. Integrated Intel I219-LM Gigabit Ethernet and Conexant CX20632 5.1 high-definition audio add connectivity without extra expansion cards that would increase power draw. The system supports up to 128 GB of memory for future expansion while staying within the existing thermal envelope.
