24-Core Ultra 9 285K Workstation

This tower workstation is built around a 24-core Intel Core Ultra 9 285K processor running at 3.7 GHz with a 360 mm liquid cooler. It targets engineers and designers who need sustained multi-thread performance for CAD, CAM and CAE modelling. The system ships with Windows 11 Pro and 128 GB of DDR5 memory in a black mid-tower case.

Professionals needing 16 GB GPU memory

The 10 TB hard drive and 1 TB NVMe SSD suit projects with large assemblies and simulation data. Buyers who want more than 192 GB of system memory or a graphics card with greater VRAM should look at alternative configurations. The four DIMM slots allow expansion up to the board limit.

Nvidia RTX PRO 2000 Blackwell 16GB

The workstation includes an Nvidia RTX PRO 2000 Blackwell graphics card with 16 GB of memory. This specification decides whether the system meets the VRAM requirements of your professional viewport and rendering workflows. The GPU is paired with a Z890 motherboard offering Thunderbolt and Wi-Fi 7 connectivity.

Questions about this item

Should I choose the 128 GB DDR5 configuration or add more memory up to the 192 GB maximum?

The system ships with 128 GB DDR5 across four slots; the motherboard supports up to 192 GB total, so you can add modules later if workloads demand it.

What does the 5.70 GHz boost clock mean for actual CAD and simulation work?

The 24-core Intel Core Ultra 9 285K can reach 5.70 GHz on lightly threaded tasks, while the 360 mm liquid cooler sustains high frequencies during long renders.

How fast is the Thunderbolt 4 port compared with the other USB connections?

Thunderbolt 4 delivers 20 Gbps, matching the front 20 Gbps Type-C port and exceeding the 10 Gbps and 5 Gbps USB-A ports on the rear I/O.
