Workstation for SolidWorks and CAD

This business desktop is built for professional modelling and simulation workloads. The twelve-core AMD Ryzen 9 9900X3D processor runs at a 4.4 GHz base frequency with up to 5.50 GHz boost. Sixty-four gigabytes of DDR5 memory and a 16 GB Nvidia RTX PRO 2000 Blackwell GPU provide the compute and graphics headroom required for large assemblies.

PCI Express x16 and 2.5G Ethernet limits

The graphics card connects through a single PCI Express x16 slot, so only one discrete GPU can be installed. Network throughput is capped at the onboard 2.5G Ethernet controller; faster 10G or fibre links would need an add-in card. The motherboard supplies four M.2 connectors, yet only one 4TB NVMe drive is populated from the factory.

12-core CPU with 128 MB L3 cache

The defining specification is the twelve-core Ryzen 9 9900X3D with 128 MB of L3 cache, which accelerates cache-sensitive CAD and CAE kernels. Buyers who need higher core counts or larger shared caches for distributed rendering should look elsewhere. The 64 GB DDR5 configuration can be expanded to 192 GB if memory capacity becomes the bottleneck.

Questions about this item

Should I pick the 4 TB NVMe or the 10 TB hard drive for active SolidWorks projects?

Use the 4 TB Samsung 990 PRO NVMe for active SolidWorks projects — its PCIe 4.0 x4 link delivers up to 7450 MB/s read and 6900 MB/s write, while the 10 TB hard drive is best for archived data.

What does the Ryzen 9 9900X3D 4.4 GHz base clock mean once the system is under a full CAD workload?

The 12-core CPU can boost up to 5.50 GHz with 128 MB L3 cache, so sustained modelling and simulation clocks will sit well above the 4.4 GHz base while the 240 mm liquid cooler keeps temperatures in check.

How do the motherboard's USB4 and 10 Gbps ports cap real-world transfer speeds?

Two USB4 ports run at 40 Gbps, three ports at 10 Gbps, and four ports at 5 Gbps; each device will negotiate its maximum supported rate up to those ceilings.
