AOOSTAR GEM12+ Pro vs WTR Pro
processor performance
The AOOSTAR GEM12+ Pro uses the Ryzen 7 PRO 8845HS, an 8-core, 16-thread chip with a 5.1GHz boost. It includes Radeon 780M graphics and supports AV1 decoding. The AOOSTAR WTR Pro features the Ryzen 7 5825U, also 8-core and 16-thread, but peaks at 4.5GHz with older Vega graphics. The 8845HS offers higher clock speeds and newer architecture for faster multitasking and media handling. The 5825U is sufficient for basic tasks but lags in raw power and modern video decoding capabilities.
storage capacity
The WTR Pro is designed for heavy data storage. It offers a 4+2 bay layout with four SATA slots and two M.2 NVMe slots, supporting up to 96TB of total storage. The GEM12+ Pro has two M.2 2280 slots for PCIe 3.0/4.0 drives, with a maximum total of 8TB. If you need a NAS for large file archives, the WTR Pro provides significantly more drive bays and capacity. The GEM12+ Pro is limited to two drives, making it less suitable for massive storage arrays.
memory speed
The GEM12+ Pro supports DDR5 memory running at 5600MHz, with slots expandable up to 128GB. This offers 35% faster bandwidth than DDR4. The WTR Pro uses DDR4 memory, with a maximum capacity of 64GB. DDR5 provides higher throughput, which benefits data-intensive applications and gaming. The WTR Pro is limited to older, slower DDR4 technology and lower maximum memory capacity. For users prioritizing speed and future-proofing, the GEM12+ Pro is the superior choice.
cooling system
The GEM12+ Pro employs a vapor chamber and CPU fan for heat dissipation. The vapor chamber spreads heat evenly across the surface to maintain performance under load. The WTR Pro uses a full metal shell with a large 12CM fan and through-air ventilation. It features intelligent fan speed adjustment and dustproof structures. The WTR Pro is optimized for 24/7 operation with lower power consumption between 15W and 25W. The GEM12+ Pro focuses on high-performance cooling for bursts of activity.
external graphics
The GEM12+ Pro includes a dedicated 64Gbps OCuLink port. This allows you to connect external graphics cards like RTX 4070 or 4080 with high bandwidth and low latency. The port operates independently of M.2 slots. The WTR Pro does not list an OCuLink port or similar high-speed eGPU interface. If you plan to use external graphics for gaming or rendering, the GEM12+ Pro provides the necessary hardware support. The WTR Pro lacks this specific expansion capability.
