Professional tower workstation

The HP Z8 G4 is a dual-processor tower workstation built for professional design, content creation, rendering and engineering workloads. It ships with two Intel Xeon Gold 6148 CPUs running at 2.40GHz, providing 40 total cores and 80 threads with hyperthreading. Windows 11 Professional is preinstalled for immediate deployment.

Sustained multi-core throughput

Six-channel DDR4 ECC memory runs at 2666MHz across 24 DIMM slots, feeding both processors for consistent performance during long rendering or simulation jobs. The 250GB NVMe SSD on a PCIe adapter card delivers fast boot and project load times. Dual Xeon architecture maintains clock speeds under continuous load without the throttling typical of single-socket designs.

Thermals and power in daily use

An 1125W power supply rated at 90% efficiency at 100V feeds the system, including the NVIDIA Quadro P2000 with 5GB GDDR5 and four Mini DP 1.4 outputs. Four internal 3.5-inch bays include acoustic dampening rails to reduce drive noise. Expansion slots support up to four PCIe x16 Gen3 graphics cards with dedicated 6+2-pin power cables included.
