HP Z4 Rack G5 Features:

  • Equipped to power the needs for advanced VFX, 3D modeling, and rendering with up to 24 cores in an Intel Xeon W-2400 CPU,[ii] support for NVIDIA RTX 6000 Ada Generation graphics,[1][iii] and up to 256 GB DDR5 memory,[iv] all with room to upgrade and expand.
  • Innovative engineering enables optimal thermal performance, allowing the workstation to handle intensive workloads without compromising productivity.
  • Built with premium components, and rigorously tested for reliability and durability, the Z4 Rack G5 provides uninterrupted performance for critical tasks.
  • With the option of HP Anyware[v], teams can access the power of the Z4 Rack from any device, delivering fast responsiveness and image quality, even under varying network connections.
  • Certified for pro apps and with HP Wolf Security for Business, it’s protected below, in, and above the OS.[vi]

Additionally, as Z by HP customers – creators, engineers, and data scientists – evolve their workflows, graphics performance has become important to their success. That’s why HP is announcing support for the new Ada Generation GPUs — NVIDIA RTX 5000NVIDIA RTX 4500, and NVIDIA RTX 4000 — across our platforms. We also currently support the NVIDIA RTX 6000. NVIDIA RTX Ada Generation GPUs offer abundant graphics memory with error-correcting code (ECC) for rendering, data science, and engineering simulation. The fourth-generation Tensor Cores provide up to 5X the model training performance and up to 5X the inference performance of the previous-generation NVIDIA Ampere architecture for faster generative AI content creation. [vii][viii]
