Sixunited AXB88: A 1.2-liter Mini PC packing 16 Cores and RTX-class iGPU muscle

If you thought ultra-compact PCs had to be underpowered, the newly announced Sixunited AXB88 makes a compelling argument to rethink that assumption. This tiny desktop – measuring just 1.2 liters in volume – crams some serious computing muscle into a chassis you could easily mistake for a router or external hard drive.

A Ryzen AI Max heartbeat – Squeezed into a compact chassis

At the core of the AXB88 is a high-end Ryzen AI Max APU with 16 CPU cores and enough integrated graphics horsepower that it’s being likened to an RTX-4060-class iGPU. That’s a bold claim, because the Nvidia RTX 4060 family – powered by the Ada Lovelace architecture – is known for solid 1080p gaming and respectable ray-tracing performance in discrete cards.

What makes this interesting isn’t just the raw numbers, but how much performance Sixunited is squeezing into such a small package – especially with a processor drawing up to 120 W of power. In most tiny form factor PCs, you see much lower TDP components that prioritize silence and efficiency over outright speed.

Memory, storage, and connectivity: Not your average mini PC

Despite the compact footprint, the AXB88 doesn’t skimp on expandability:

• Up to 128 GB of RAM – unusual for systems this small.
• Dual SSD bays – room for both blazing-fast NVMe storage and generous capacity.
• USB4 support – high-bandwidth ports that pair well with eGPUs and fast peripherals.
• USB 3.2 Gen2, SD card slot, RJ45 Ethernet and HDMI output – enough to keep most workflows humming.

That connectivity suite bridges the gap between a basic NUC-style PC and a more full-featured desktop, giving users plenty of flexibility for productivity, media, and even light gaming setups.

Who this tiny titan is for

So who actually benefits from a near-pint-sized powerhouse like the AXB88?

• Content creators who need compact hardware for editing and rendering on the go.
• Home office users looking for professional-grade performance without a bulky tower.
• Gamers on space-restricted desks – especially those happy with mid-range graphics performance.
• Tech enthusiasts who love packing real power into tiny builds.

Importantly, while the integrated graphics are described as RTX-4060-level, keep in mind that this refers to the APU’s performance potential, not a discrete GPU sitting inside the chassis. True dedicated GPUs like the RTX 4060 still have the edge in raw gaming benchmarks and VRAM bandwidth.

The cooling question

One point that merits attention: putting a 120 W APU into such a small case naturally raises eyebrows about thermals. Efficient cooling solutions and careful airflow design are crucial in systems this compact – especially when you’re also juggling high RAM capacities and dual SSDs. Sixunited hasn’t released full thermal data yet, so it’ll be interesting to see how the AXB88 handles sustained loads.

When to expect one (and what’s missing)

Sixunited hasn’t revealed pricing yet, but the company says the AXB88 will go on sale in March.

For enthusiasts and professionals who want desktop-class performance in a tiny package, this mini PC could be a very compelling choice – provided the thermal design holds up and pricing lands in a sensible range.

If you’re assembling a compact workstation or looking to squeeze serious performance out of a small footprint, the AXB88 is one to watch.
