12-Core AMD Ryzen 9 9900X3D Workstation

This business desktop combines a 12-core AMD Ryzen 9 9900X3D processor at 4.4 GHz with an Nvidia RTX PRO 4500 Blackwell GPU featuring 32GB of video memory. It ships with 32GB of DDR5 system memory, a 1TB NVMe SSD and a 10TB hard drive. The system targets engineers and designers running SolidWorks, CAD, CAM and CAE modelling workloads.

PCI Express x16 Graphics and 2.5G Ethernet Limits

The GPU connects through a PCI Express x16 slot, which defines the bandwidth ceiling for the RTX PRO 4500 Blackwell. Network traffic is capped at 2.5 Gbps by the Intel 2.5G Ethernet controller, while Wi-Fi 7 provides a wireless alternative. The motherboard rear I/O includes two USB4 ports at 40 Gbps, one USB 10 Gbps port, three USB 5 Gbps ports and four USB 2.0 ports for peripheral connectivity.

32GB DDR5 Memory and 192GB Maximum Capacity

The installed 32GB DDR5 kit handles typical modelling datasets and multitasking, while the board supports up to 192GB for larger simulations. The 1TB NVMe drive delivers read speeds up to 7450 MB/s and write speeds up to 6900 MB/s for fast project loading. The 10TB hard drive with 256MB cache provides deep archival storage, though its mechanical latency limits random-access performance.

Questions about this item

Should I pick the 1 TB NVMe or the 10 TB HDD as my main drive?

Use the 1 TB NVMe for the OS and active projects — it reads up to 7450 MB/sec and writes up to 6900 MB/sec. Keep the 10 TB HDD for archives and large asset libraries.

What does the 4.4 GHz base clock on the 12-core Ryzen 9 9900X3D mean for my SolidWorks assemblies?

The 12 cores and 24 threads run at 4.4 GHz base and can boost to 5.50 GHz with 128 MB L3 cache, giving strong single-thread speed for rebuilds and enough threads for simulation solves.

Will the PCI Express x16 slot and 2.5G Ethernet keep up with the RTX PRO 4500 Blackwell and network renders?

The GPU connects through a full PCI Express x16 link, and the Intel 2.5G Ethernet port handles multi-machine render traffic without saturating a 1 Gb link.
