Built for professional CAD and AI workloads

This workstation combines a 12-core Ryzen 9 9900X processor with 128GB of DDR5 memory and an Nvidia RTX PRO 4000 Blackwell graphics card. It targets engineers and researchers who need certified drivers and large local datasets. The 240mm liquid cooler keeps the CPU stable during extended render or training runs.

GPU memory decides fit for large models

The RTX PRO 4000 Blackwell provides 24GB of video memory, which determines whether your datasets and model weights fit without offloading to system RAM. Buyers who need more VRAM for bigger scenes or larger batch sizes cannot expand this limit on this card.

Fast NVMe storage and high-speed connectivity

Two 4TB Samsung 990 PRO drives deliver up to 7450 MB/s read and 6900 MB/s write speeds for active project files. The motherboard adds USB4 at 40Gbps, Wi-Fi 7, 2.5G Ethernet and four M.2 slots for future expansion. A 10TB hard drive supplies bulk capacity for archives.
