A 1.2L Tiny Strix Halo PC Built for Local LLM Inference Will Hit the Market Soon

A new Strix Halo mini PC from Sixunited has appeared, and the headline feature is size. At just 1.2 liters, this is the smallest Ryzen AI Max+ 395 system seen so far. For local LLM users focused on memory bandwidth and footprint rather than raw wattage, this is a meaningful data point.

Smallest Strix Halo Form Factor So Far

The system measures 160 x 160 x 47 mm, putting it well below existing Strix Halo mini PCs. The Beelink GTR9 Pro measures 180 x 180 x 90.8 mm, the HP Z2 Mini G1a is about 168 x 215 x 85.5 mm, and the Minisforum MS-S1MAX comes in at 222.1 x 206.3 x 77.1 mm. In both height and overall volume, this Sixunited system is clearly smaller, which explains the tighter power budget.

Strix Halo at 120W Instead of 170W

This machine runs Strix Halo at a 120W TDP. That is lower than other Strix Halo mini PCs such as the GMKTEK EVOX2 or HP Z2 Mini configurations that operate closer to 170W. The lower power limit suggests reduced sustained GPU performance, but also enables the compact chassis and simpler cooling. For LLM inference workloads that are typically memory-bound, this trade-off may be reasonable.

Memory-Centric Design for Local Models

The core strength remains the memory configuration. LPDDR5x-8000 on a 256-bit interface, configurable up to 128GB, is the key enabler for running larger quantized models locally. For 7B to 70B class models at 4-bit, unified memory capacity and bandwidth often matter more than peak compute.

Storage, I/O, and Connectivity

Storage includes two M.2 2280 PCIe 4.0 x4 slots, enough for fast model storage and quick load times. Front I/O provides two USB4 40Gbps ports, SD 4.0, and an audio combo jack. The rear adds two USB 3.2 Gen2 ports, 2.5G LAN, HDMI 2.1, and DC-in. Power is supplied by a 230W external adapter, leaving headroom despite the 120W platform limit.

Two Configurations, Not AXN88

Sixunited lists two configurations for this system: AXN88-H01-SZ-R52 and AXN88-H02-TBD-R52. There is no single model named AXN88 on its own, only these two SKUs. Mass production is currently listed for March 2026.

Part of a Broader Sixunited Strix Halo Line

This is also not Sixunited’s first Strix Halo design. The company has already announced the XN77 laptop, a STHT1 motherboard and the XB35 mini PC, all of them based on Strix Halo and still pending market release. This 1.2L system fits into a broader push by Sixunited to cover multiple form factors around the same APU platform. They also have a motherboards  

Conclusion

This 1.2L Sixunited Strix Halo mini PC sets a new low mark for size. For local LLM enthusiasts prioritizing memory bandwidth and compactness over maximum power, it is a design worth watching.
