20-Core AI Workstation Desktop

The Adamant Custom system pairs a 20-core Intel Core Ultra 7 265K processor with an Nvidia GeForce RTX 5080 graphics card. It ships with Windows 11 Pro installed and is configured for rendering, modelling and AI learning workloads. Liquid cooling keeps the CPU at stable temperatures during sustained compute tasks.

64GB DDR5 Memory Capacity

The platform includes 64GB of DDR5 memory across four slots with support for up to 192GB total. This capacity determines whether the machine can hold large datasets and complex scenes in memory without swapping. Buyers who need more memory headroom for heavy simulation work should verify the 192GB ceiling before ordering.

1TB NVMe PRO SSD and 10TB HDD Storage

A Samsung 990 PRO PCIe 4.0x4 drive delivers read speeds up to 7450 MB/sec and write speeds up to 6900 MB/sec for the operating system and active projects. The 10TB hard drive adds 256MB cache bulk storage for archives and media libraries. Users who want a second high-speed NVMe volume must add it themselves.
