BOSGAME M4 Plus Review: Ryzen 9 7940HS & OCuLink Gaming Powerhouse

In the current Mini PC landscape, you usually have to choose between a premium price tag or limited expandability. Brands like Geekom and Beelink offer fantastic, sleek devices, but they often restrict you to USB4 for external graphics. The BOSGAME M4 Plus shatters this limitation.

Powered by the formidable AMD Ryzen 9 7940HS (up to 5.2GHz), this machine is already a top-tier performer out of the box. But its secret weapon is the OCuLink port. This interface offers 63Gbps of bandwidth—significantly more than Thunderbolt 4 or USB4—allowing you to connect desktop graphics cards with minimal performance loss. Combined with 32GB of DDR5 RAM and a 1TB SSD included, the M4 Plus positions itself not just as a mini PC, but as a modular workstation foundation.

The BOSGAME M4 Plus prioritizes function over form. While it lacks the unibody aluminum finish of the Beelink SER8, its industrial design is optimized for airflow and connectivity. The chassis is robust, featuring ample ventilation to tame the 54W TDP of the Ryzen 9 processor.

Connectivity is where this model truly shines. It is one of the few consumer units offering Dual 2.5G LAN ports, perfect for home labs, virtualization, or separating network traffic. Wireless duties are handled by reliable Wi-Fi 6 and Bluetooth 5.2.

The AMD Ryzen 9 7940HS is a beast. Built on the Zen 4 architecture with 4nm process technology, it features 8 cores and 16 threads capable of boosting up to 5.2GHz. It also includes the Ryzen AI engine (XDNA), making it future-proof for local AI workloads.

In CPU-heavy tasks, the Ryzen 9 7940HS rivals desktop processors from just a few years ago. It scores significantly higher than the Ryzen 7 7840HS found in cheaper units and trades blows with the newer Ryzen 9 8945HS found in the much more expensive Geekom A8.

The integrated Radeon 780M graphics card is capable of smooth 1080p gaming on its own. You can expect playable frame rates in competitive titles like Valorant, CS2, and League of Legends at high settings. Even heavy titles like Cyberpunk 2077 are playable at 1080p Low/Medium settings with FSR enabled.

While the iGPU is great, the OCuLink port is the game changer. By connecting a dedicated GPU dock (like the Aoostar AG01 or Minisforum DEG1), you bypass the limitations of USB4. OCuLink provides a near-native PCIe connection.

When paired with an NVIDIA RTX 4070 via OCuLink, the BOSGAME M4 Plus transforms into a 4K gaming rig, suffering almost no performance loss compared to a desktop PC. This makes it a far superior choice for gamers compared to the Beelink SER8, which relies solely on USB4 for eGPU connectivity (losing 15-20% performance).

The M4 Plus enters a fierce market. Here is how it stands against the heavyweights.

Verdict: Choose the Geekom A8 if you need the absolute smallest size and premium build. Choose the Beelink SER8 for silence and Mac-like aesthetics. But choose the BOSGAME M4 Plus if you want the most performance and expandability for your money.
