Workstation-class desktop

This desktop is built around a sixteen-core AMD Ryzen 9 9950X3D processor and an NVIDIA RTX A4000 graphics card with sixteen gigabytes of memory. It ships with 192GB of DDR5 memory, an 8TB NVMe solid-state array and a 10TB hard drive. The system targets engineers and designers who need high core counts and professional GPU drivers for CAD, CAM and CAE workloads.

PCIe 4.0 storage ceiling

The two Samsung 990 PRO M.2 drives operate over a PCIe 4.0 x4 link, delivering sequential reads up to 7450 MB/s and writes up to 6900 MB/s. That interface caps the maximum throughput of the boot and scratch volumes. Any future drive upgrade must also use the PCIe 4.0 x4 standard to reach these speeds.

Motherboard and case clearance

The PRIME X870-P motherboard provides four M.2 slots, two of which are occupied by the factory SSDs. The Antec P20 mid-tower case measures 469 mm deep, 220 mm wide and 490 mm high, with a 360 mm liquid-cooler radiator already installed. Verify that any additional expansion cards or storage devices fit within the remaining internal bays and the front-panel USB layout.

Questions about this item

Should I pick the 192 GB DDR5 option or a smaller kit for this Ryzen 9 9950X3D workstation?

The board has four slots and supports a maximum of 192 GB, so the 192 GB kit fills every slot and leaves no room for later upgrades. Choose a smaller kit only if you want free slots for future expansion.

What does the 5.70 GHz boost clock mean once the 16-core CPU is inside this liquid-cooled tower?

The 5.70 GHz figure is the maximum single-core boost the Ryzen 9 9950X3D can reach under light loads; sustained all-core speeds will be lower, but the 360 mm liquid cooler keeps thermals in check for long renders.

How fast are the two 4 TB Samsung 990 PRO drives on the X870 motherboard's PCIe 4.0 M.2 slots?

Each drive is rated for up to 7450 MB/s read and 6900 MB/s write on the PCIe 4.0 x4 interface, so the pair delivers that speed independently for OS, cache and project files.
