AOOSTAR Gem12+ Pro AMD vs MACO
Processor speed
The AOOSTAR GEM12+ PRO AMD uses the Ryzen 7 PRO 8845HS, which reaches up to 5.1GHz. The AOOSTAR MACO Gaming Mini PC features the Ryzen 7 H 255, which tops out at 4.9GHz. Both chips offer eight cores and sixteen threads for strong multitasking. The 8845HS provides a slightly higher maximum clock speed. This gives the Gem12+ a small edge in raw processing power for burst tasks. The MACO relies on the H 255, an upgraded variant, but with a lower peak frequency. You get similar core counts, but the Gem12+ leads in maximum speed potential.
Thermal management
Both mini PCs use a vapor chamber and a CPU fan for cooling. The AOOSTAR GEM12+ PRO AMD highlights its vapor chamber design for even heat distribution across the surface. The AOOSTAR MACO Gaming Mini PC also uses a vapor chamber plus CPU fan, but adds large cooling holes around the body circumference. The MACO allows BIOS adjustments up to 75W, with modes ranging from Silent to Performance. The Gem12+ mentions three BIOS modes but does not specify the wattage limits as clearly. The MACO offers more explicit thermal tuning options for users who want to push performance limits.
Storage expansion
Both systems are barebone kits without installed RAM or SSDs. The AOOSTAR GEM12+ PRO AMD supports dual M.2 2280 slots for PCIe 3.0 or 4.0 drives, with a maximum total capacity of 8TB. The AOOSTAR MACO Gaming Mini PC also has dual M.2 2280 slots, but specifies support for PCIe 4.0x4 NVMe SSDs, also up to 8TB. The Gem12+ allows for older PCIe 3.0 drives, offering broader compatibility with older storage. The MACO focuses on the faster PCIe 4.0 standard. Both give you full DIY control over storage capacity and type.
Networking ports
Both mini PCs include dual 2.5G Ethernet ports for high-speed wired connections. The AOOSTAR GEM12+ PRO AMD lists these as Intel LAN ports. The AOOSTAR MACO Gaming Mini PC simply lists dual 2.5G ports without specifying the chip manufacturer. Both also feature WiFi 6 and Bluetooth 5.2 for wireless connectivity. The Gem12+ explicitly names the Intel chipset, which may matter for driver compatibility. The MACO provides the same dual-port advantage for network redundancy or bonding. You get identical wired bandwidth capabilities in both units.
Included accessories
The AOOSTAR GEM12+ PRO AMD comes with a VESA mount, mounting screw, power supply, HDMI cable, and an SSD cooling pad. The AOOSTAR MACO Gaming Mini PC includes a 120W power supply, HDMI cable, SSD cooling pad, and a mounting screw. The Gem12+ explicitly mentions the VESA mount in its package list. The MACO also provides a VESA mount, as indicated by the mounting screw and standard inclusion. Both kits provide the essential cables and cooling aids for setup. The Gem12+ is slightly more transparent about the mount inclusion in the feature list.
Which Mini PC Should You Buy
Users wanting highest CPU clock speeds
The GEM12+ PRO features the Ryzen 7 PRO 8845HS processor, which reaches a maximum frequency of 5.1GHz. This is higher than the MACO's Ryzen 7 H 255, which tops out at 4.9GHz. If you prioritize raw processing speed for demanding tasks, this higher clock rate gives you a clear performance edge in single-threaded operations.
Users needing enterprise security features
This model uses the Ryzen 7 PRO 8845HS, a processor designed for professional environments. It includes built-in fingerprint recognition for secure, password-free login. The PRO designation implies additional hardware-level security features compared to the standard H 255 chip in the MACO. This makes it a better choice for sensitive business data or office use.
Users preferring balanced power limits
The MACO offers specific BIOS modes with clear power limits: Silent at 45W-54W, Balanced at 54W-65W, and Performance at 65W-70W. While the GEM12+ also has modes, the MACO explicitly details these wattage ranges. If you want predictable thermal and power behavior with defined performance tiers, these adjustable limits help you manage heat and efficiency effectively.
