Core configuration

This business desktop combines a 24-core Intel Core i9-14900K processor with 128 GB of DDR5 memory and an NVIDIA RTX A4000 graphics card. A 4 TB NVMe SSD and a 10 TB HDD provide fast primary storage plus deep capacity for project archives. The system ships with Windows 11 Pro and a 360 mm liquid cooler in a mid-tower case.

Workstation focus

The build suits engineers and designers who need certified professional drivers and large memory capacity for CAD, CAE or rendering workloads. Buyers who need ECC memory, dual-GPU configurations or a rack-mount chassis should look at a different class of machine. The mid-tower form factor also limits internal expansion compared with full-tower workstations.

Deciding specification

The RTX A4000 is a professional visualisation GPU with ISV-certified drivers; it is not a GeForce gaming card and does not carry consumer gaming features. If your software stack requires certified drivers for SolidWorks, CATIA or similar ISV applications, this GPU is the correct choice. If you only need raw rasterisation performance for gaming, a consumer card would be more cost-effective.

Questions about this item

What real-world performance can I expect from the 24-core Intel Core i9-14900K in this workstation?

The 24-core Intel Core i9-14900K runs at 3.2 GHz base and can boost up to 6.00 GHz with 36 MB L3 cache, delivering strong multi-threaded throughput for CAD, CAM and CAE modelling tasks.

What PCIe generation does the 4 TB Samsung 990 PRO use and what throughput ceiling does that impose?

The 4 TB Samsung 990 PRO connects via PCIe 4.0 x4, providing sequential reads up to 7450 MB/s and writes up to 6900 MB/s.

Will the 360 mm liquid cooler and RTX A4000 fit inside the Antec P20 mid-tower case?

Yes, the Antec P20 mid-tower supports 360 mm radiators and full-length graphics cards, so the 360 mm AIO cooler and RTX A4000 are both accommodated.
