Workstation PC with 12-core Ryzen 9 9900X3D

This desktop combines a 12-core AMD Ryzen 9 9900X3D processor with an Nvidia GeForce RTX 5080 graphics card. It targets professionals who need high multi-threaded performance for modelling, video editing, rendering and AI learning workloads. The system ships with Windows 11 Pro installed.

PCIe 4.0 NVMe storage and DDR5 memory limits

The 2 TB Samsung 990 PRO SSD connects via a PCIe 4.0 x4 interface, delivering sequential reads up to 7450 MB/s and writes up to 6900 MB/s. The motherboard provides four DDR5 slots supporting a maximum of 192 GB, so the installed 64 GB kit can be expanded later.

Check case clearance and motherboard USB headers

The chassis measures 447 mm deep, 215 mm wide and 469 mm high with internal bays for two 3.5-inch and two 2.5-inch drives. Front-panel I/O includes one USB 3.2 Gen 2x2 Type-C port, two USB 3.0 ports and audio jacks. Verify that your workspace accommodates these dimensions and that any additional internal USB devices match the available mid-board headers.

Questions about this item

Should I pick the 64 GB DDR5 option or add more memory later?

The board has four DDR5 slots and supports up to 192 GB, so the 64 GB kit leaves room for expansion.

What does the 5.50 GHz boost clock on the 12-core Ryzen 9 9900X3D mean for actual workloads?

It gives high single-thread speed for gaming and responsive modelling while the 128 MB L3 cache keeps multi-thread rendering smooth.

How fast is the PCIe 4.0 x4 link for the Samsung 990 PRO 2 TB SSD in practice?

Sequential reads reach 7450 MB/s and writes 6900 MB/s, saturating the four-lane Gen 4 interface.
