Dual 20‑Core Xeon Gold Workstation

The HP Z8 G4 tower ships with two Intel Xeon Gold 6148 processors, each running at 2.40 GHz with 20 cores. This dual‑socket LGA 3647 configuration targets professionals who need sustained multi‑threaded throughput for rendering, simulation or large‑scale data analysis. It is not suited for buyers who only need single‑thread speed or a compact desktop form factor.

RTX A4500 16 GB GPU and Windows 10 Pro

The installed NVIDIA RTX A4500 adds 16 GB of video memory for GPU‑accelerated workloads such as 3D viewport performance, compute tasks and multi‑display output. Windows 10 Pro is pre‑loaded, and a DVD‑RW drive is included for legacy media. Buyers who require a newer OS licence or a different GPU tier will need to arrange that separately.

16 GB DDR4‑2666 and 2 TB NVMe with 3 TB ceiling

The system arrives with 16 GB of PC4‑2666 DDR4 across 24 DIMM slots, leaving ample headroom to reach the 3 TB maximum supported by the Intel C622 chipset. A 2 TB NVMe 2280 TLC drive provides fast primary storage, and the controller supports RAID 0, 1 and 10 for additional arrays. Users whose datasets exceed the installed memory or capacity must add modules and drives.

Questions about this item

Will the 16 GB DDR4 memory need to be expanded to reach the 3 TB maximum?

The workstation has 24 memory slots and currently uses 16 GB, so additional DDR4 modules can be installed up to the 3 TB limit.

Which component hits its thermal or power ceiling first when all 40 cores and the RTX A4500 run continuously?

The dual Xeon Gold 6148 processors and the RTX A4500 GPU share the tower’s air-cooling system, so sustained loads will be limited by the chassis thermal capacity.

How loud and hot does the tower get when the two Xeon CPUs and the RTX A4500 run all day?

The system relies on standard tower airflow to cool both 20‑core processors and the GPU, so extended operation will raise chassis temperature and fan noise proportionally to workload.
