Bosgame M5 Brings 128GB Local AI to a Mini Desktop

The interesting question about a local AI desktop is not how fast it is. It is how much model you can fit before you run out of memory. ServeTheHome published its review of the Bosgame M5 on August 21, 2026, and the verdict lands squarely on that point: this is one of the least expensive ways to get 128GB of LPDDR5X in front of an AMD Ryzen AI Max+ 395.

• The M5 pairs a Ryzen AI Max+ 395 with 128GB of soldered LPDDR5X and two M.2 slots for storage
• ServeTheHome puts it $500 to $1,100 below AMD's own Ryzen AI Halo developer machine at matching CPU and memory specs
• Bosgame lists the 128GB configuration with a 2TB SSD at an introductory $1,699, with deal trackers showing it near $1,840 at other times
• Connectivity covers two USB4 ports, two USB 3.2 Gen 2 ports, HDMI, DisplayPort, an SD reader, Wi-Fi 7, and 2.5GbE

Why 128GB of Unified Memory Is the Whole Point

The Ryzen AI Max+ 395, better known by its Strix Halo codename, is a strange and useful chip. It combines 16 Zen 5 CPU cores, a Radeon 8060S integrated GPU, and an XDNA 2 NPU, and it addresses a single large pool of LPDDR5X rather than a small dedicated frame buffer. On a 128GB machine, a very large share of that pool can be handed to the graphics side.

That is the difference between reading about a large open-weight model and actually running one. A discrete card with 24GB of VRAM forces aggressive quantization or offloading to system memory, which collapses tokens per second. A 128GB unified pool lets a much bigger model sit resident. It is the same argument that drove our best mini PC for local LLMs buyer's guide, and Strix Halo boxes keep winning it on capacity rather than raw compute.

What Does the Bosgame M5 Actually Cost?

Pricing on this class of machine moves around, so treat any single figure with care. Bosgame's own store has listed the 128GB and 2TB configuration at $1,699 as an introductory price against a higher list price, and deal aggregators have tracked it near $1,840 with shipping included at other points. Lower-memory 96GB variants sit below that.

The comparison that matters more is relative. ServeTheHome reports the M5 coming in $500 to $1,100 cheaper than AMD's Ryzen AI Halo developer platform with the same processor and the same memory capacity. When the silicon and the memory are identical, that gap is close to pure savings.

Where the M5 Trades Away Something

ServeTheHome's main note for improvement is networking. The M5 ships with 2.5GbE, and on a machine designed to hold and serve very large models, a 10GbE port would suit the workload better. Several competing compact systems in this bracket have already made that jump, so it stands out.

This is also not a low-power mini PC in the traditional sense. A 16-core APU with a large integrated GPU pulls real wattage under load, and the M5 exposes three performance modes through a front-panel button so you can dial that behaviour up or down. The chassis leans gaming-adjacent, with an angled shell, an RGB strip, and a stand for vertical mounting, which will either delight or fade into the background depending on where it sits.

The port selection is a genuine strength. Two USB4 connections, two USB 3.2 Gen 2 ports, HDMI, DisplayPort, an SD card reader, and audio jacks give it more real-world flexibility than several rival AI desktops that assume you will only ever plug in a monitor and a keyboard.

Who Should Look at This

Anyone experimenting with large local models, doing GPU rendering, or compiling on a desk where a full tower will not fit. The M5 is not the fastest machine in this space and it is not the quietest, but capacity per dollar decides which models you can run at all, and on that metric it currently sits near the front of the mini PC field.
