16-Core Workstation for Engineering

This Adamant Custom desktop pairs a 16-core AMD Ryzen 9 9950X3D with an NVIDIA RTX A4000 16GB GPU. It targets engineers and modellers running SolidWorks, CAD, CAM or CAE workloads that demand high single-thread frequency and certified professional graphics drivers. The system ships with Windows 11 Pro and 128GB of DDR5 memory.

PCIe 4.0 Storage and Connectivity Limits

The 4TB Samsung 990 PRO SSD operates over a PCIe 4.0 x4 link, delivering sequential reads up to 7450 MB/sec and writes up to 6900 MB/sec. The Gigabyte X870 EAGLE motherboard provides three M.2 connectors and four SATA 6Gb/s ports for additional drives. Rear I/O includes two USB4 Type-C ports, one USB 3.2 Gen 2, one USB 3.2 Gen 1 and four USB 2.0 ports.

128GB Memory with 192GB Ceiling

The platform supports a maximum of 192GB across four DDR5 slots, leaving headroom for a future upgrade from the installed 128GB. The 10TB hard drive adds bulk capacity for project archives. The RTX A4000 16GB frame buffer suits large assemblies and GPU-accelerated rendering, while the 850W 80 PLUS Bronze PSU powers the complete build.

Questions about this item

Should I choose the 128 GB DDR5 configuration or the maximum 192 GB supported by the board?

The system ships with 128 GB DDR5 across four slots; the X870 EAGLE motherboard can reach 192 GB if you add modules later.

What does the Ryzen 9 9950X3D 4.3 GHz base and 5.70 GHz boost mean for actual workloads?

Sixteen cores and 32 threads at those clocks give strong multi-thread throughput for CAD, simulation and rendering while the 360 mm liquid cooler sustains boost.

How fast is the Samsung 990 PRO 4 TB NVMe drive on the PCIe 4.0 x4 interface?

Sequential reads up to 7450 MB/s and writes up to 6900 MB/s, limited by the PCIe 4.0 x4 link on the motherboard M.2 slot.
