The GMKtec K12 barebones mini PC with AMD Ryzen 7 8745H APU, OCuLink support, and dual 2.5G Ethernet is now available for just $350, offering impressive connectivity and upgrade potential for budget-conscious gamers and content creators.
The GMKtec K12 mini PC has landed at an attractive price point, with the barebones variant now available for just $350 on GMKtec's official website. This compact gaming rig packs an 8-core AMD Ryzen 7 H 255 APU (essentially a rebranded Ryzen 7 8745H) that delivers performance competitive with Apple's M3 Pro and Intel's Core Ultra 9 185H in synthetic benchmarks, making it a compelling option for those who can supply their own memory and storage.

AMD Hawk Point APU Delivers Mid-Range Performance
The heart of the K12 is AMD's Hawk Point APU, featuring 8 cores and 16 threads built on the Zen 4 architecture. While this processor is essentially a rebranded version of the Ryzen 7 8745H, it still offers respectable multi-core performance that should handle most moderately intensive workloads with ease. Our detailed review confirms that the CPU performance is more than adequate for everyday computing tasks, content creation, and even some light gaming.
However, the integrated Radeon 780M GPU, which is now over three years old, does limit gaming potential. The iGPU can handle lightweight gaming and non-intensive workloads, but serious gamers will want to take advantage of the OCuLink port for external GPU setups. This feature is particularly noteworthy as it allows users to significantly boost graphics performance through a high-speed eGPU connection, transforming this compact system into a capable gaming machine.

The dual 2.5G Ethernet ports are another standout feature, offering exceptional networking capabilities that are rare in mini PCs at this price point. This makes the K12 particularly appealing for network-intensive applications, content creators working with large files, or anyone who needs reliable, high-speed network connectivity.
Impressive I/O Selection and Expandability
One of the K12's strongest selling points is its comprehensive port selection and expandability options. The system features:
- USB 4 and USB 3.2 Gen 2 Type-C
- Dual USB 2.0 Type-A
- Triple USB 3.2 Gen 2 Type-A
- OCuLink for eGPU support
- HDMI 2.1 and DisplayPort 1.4
- Dual 2.5G Ethernet
- 3.5mm audio jack
The triple M.2 slots provide exceptional storage flexibility, allowing users to configure the system with multiple drives for different purposes - perhaps an NVMe SSD for the operating system and applications, another for active projects, and a third for archival storage.
Notable Drawbacks to Consider
Despite its attractive price and features, the K12 isn't without flaws. Our in-depth review revealed that the vapor chamber cooling system with dual fans can become audibly loud under load, which might be distracting in quiet environments. Additionally, the performance is essentially identical to the Ryzen 7 8745H, so don't expect any surprises or hidden performance gains from the rebranded APU.

The barebones configuration means you'll need to supply your own RAM and storage, which could add significant cost depending on current market prices. However, given the recent spike in memory and storage prices, this approach might actually save money for those who already have compatible components or can source them at reasonable prices.
Value Proposition at $350
At its current price point, the GMKtec K12 offers solid value for budget-conscious users who prioritize connectivity and upgrade potential over raw performance. The combination of OCuLink support, dual 2.5G Ethernet, comprehensive port selection, and triple M.2 slots makes it particularly appealing for:
- Content creators needing fast storage and network connectivity
- Gamers who plan to use an eGPU
- Network administrators or IT professionals
- Users who want a compact system with excellent expansion options
For those who prefer a complete system without the hassle of sourcing components separately, GMKtec also offers a pre-configured variant with 32GB RAM and 512GB storage for just under $600 on Amazon. This option eliminates the barebones setup process while still providing excellent value for a compact gaming PC with these specifications.
