Workstation built for SolidWorks and AI learning

This business desktop pairs an eight-core Ryzen 7 9800X3D processor with a 240mm liquid cooler, 128GB of DDR5 memory and an Nvidia RTX PRO 4000 Blackwell graphics card with 24GB of VRAM. Windows 11 Pro 64-bit is pre-installed. The system targets engineers and researchers who need strong single-thread performance and professional GPU drivers.

PCI Express x16 graphics interface

The GPU connects through a PCI Express x16 slot while the motherboard supports up to 192GB of DDR5 across its four M.2 connectors and memory slots. Rear I/O includes two USB4 ports at 40Gbps, three 10Gbps USB ports, four 5Gbps USB ports and one USB 2.0 port. Wi-Fi 7 and 2.5G Ethernet handle network traffic.

4TB NVMe boot drive plus 10TB mechanical storage

The Samsung 990 PRO SSD delivers sequential reads up to 7450MB/s and writes up to 6900MB/s for active project files. A 10TB hard drive with 256MB cache provides bulk capacity for archives and datasets. Builders who need more than 192GB of RAM or additional GPU compute will need a different platform.
