Dual Xeon Gold 6148 Workstation

The HP Z8 G4 tower workstation arrives new with two Intel Xeon Gold 6148 processors, each running at 2.40 GHz with 20 cores for 40 total threads. It includes 16 GB of DDR4 PC4-2666 memory across 24 slots and a 2 TB M.2 NVMe 2280 TLC drive. Dual NVIDIA Quadro P4000 GPUs provide 16 GB of combined video memory for professional visualisation workloads.

Suited For And Not Suited For

This system suits professionals who need dual-socket compute density and certified professional graphics for 3D rendering, simulation or video editing in a tower form factor. Buyers who require higher installed memory capacity or additional GPU accelerators should look elsewhere. The platform supports a maximum of two processors and the current configuration occupies both sockets.

Deciding Specification

The defining specification is the dual 20-core Xeon Gold 6148 configuration delivering 40 threads at a base frequency of 2.40 GHz. This CPU foundation determines the workstation's capacity for heavily threaded professional applications and governs the memory bandwidth available across the 24 DDR4 slots.

Soalan tentang produk ini

What comes in the box and what must I buy separately?

The unit ships with two Xeon Gold 6148 processors, 16 GB DDR4 memory, a 2 TB NVMe drive, two Quadro P4000 cards with 16 GB video memory, a DVD writer and Windows 10 Pro. Additional DDR4 modules up to 3 TB total and extra storage drives are purchased separately.

Should I choose the 16 GB DDR4 configuration or add more memory now?

The workstation has 24 DDR4 slots and supports up to 3 TB. The installed 16 GB uses only a few slots, leaving room to expand later. Add modules now if your workloads — such as large simulations or 8 K editing — regularly exceed 16 GB.

What does the 2.4 GHz Xeon speed mean for real rendering and simulation tasks?

Each of the two 20-core Xeon Gold 6148 CPUs runs at 2.40 GHz, giving 40 cores and 80 threads total. That core count lets the Z8 G4 distribute 3D rendering, complex simulations and AI training across many threads, reducing frame times and iteration cycles compared with lower-core alternatives.
