Gaming mini PC for AI workloads

The ROG NUC (2025) packs an Intel Core Ultra 9 275HX 24-Core processor and NVIDIA GeForce RTX 5080 Mobile GPU into a 3L chassis. It ships with 32GB CSO-DIMM DDR5-6400MHz memory and a 2TB M.2 2280 PCIe Gen4x4 NVMe SSD. Windows 11 Home is pre-installed for immediate use.

Limits of mobile GPU and soldered memory

The RTX 5080 Mobile GPU delivers high frame rates with DLSS technology, yet its power envelope is constrained by the 330W supply. Memory uses CSO-DIMM modules that are not user-replaceable, so the 32GB capacity is fixed. Thunderbolt 4 and 2.5G Ethernet provide fast I/O, but total bandwidth remains bound to the mobile platform.

Tool-free access and triple-fan cooling

Thumb screws open the case for quick SSD upgrades without tools. Three fans and dual vapor chambers keep temperatures low under load while running quietly. Intel Killer Wi-Fi 7 BE1750x and Bluetooth 5.4 handle wireless traffic. Aura Sync ARGB lighting adds customisation. The 330W adapter is external, so desk space must accommodate it.

Questions about this item

Should I pick the 32 GB DDR5-6400 version or look for a different capacity?

This unit ships with 32 GB of DDR5-6400 memory in a 2 x 16 GB CSO-DIMM layout, so the capacity and speed are fixed for this model.

What does the 24-core Intel Core Ultra 9 275HX actually deliver inside this 3 L chassis?

The 24-core processor combines 36 MB L3 cache and 40 MB L2 cache with a 330 W power supply and triple-fan vapor-chamber cooling to sustain high clocks during extended gaming or AI workloads.

Which Thunderbolt standard is fitted and what throughput does it cap at?

Thunderbolt 4 is included, providing up to 40 Gbps of bandwidth for external GPUs, high-speed storage or dual 4 K displays through a single port.
