HP Z6 G5
Built around a 20-core Intel Xeon w5-3525 and NVIDIA RTX 4000 Ada with 20GB VRAM, this tower delivers certified reliability for simulation and advanced visual effects with room for up to three GPUs. The 1125W power supply and ECC memory support heavy expansion, though the 16GB RAM and 512GB SSD are minimal starting points for a system of this caliber. It’s best for engineering teams and data scientists running multi-GPU compute workloads who need a scalable, ISV-certified chassis.
