GMKtec G11
Published on
The GMKtec G11 is a budget mini PC built around the AMD Ryzen Embedded R2514, a quad-core, eight-thread chip that GMKtec positions for continuous 24/7 operation in office, home-server, and light industrial roles. What sets the G11 apart from most sub-$350 mini PCs is its networking: two 2.5 Gigabit Ethernet ports feed straight into router, firewall, or NAS workloads, and WiFi 6E with Bluetooth 5.2 covers wireless duty. It ships with Windows 11 Pro, drives up to three independent 4K displays through dual HDMI and a USB-C port, and keeps its internals open with two DDR4 SO-DIMM slots and two M.2 2280 NVMe bays. The R2514 is 2019-generation Zen+ silicon, so this is not a performance machine; it is a low-power, well-connected box for people who care more about ports and uptime than raw speed.

Detailed Insights into the GMKtec G11
The G11 measures roughly 5 by 5 inches with a height near 2 inches (128.5 by 127 by 51 mm) and weighs about 1.1 pounds, small enough to hide behind a monitor with the bundled VESA bracket. The front panel carries a power button, a USB-C port, two USB 3.2 Gen 2 Type-A ports at 10Gbps, and a 3.5mm combo audio jack. The rear adds two more USB 3.2 Gen 1 Type-A ports at 5Gbps, two HDMI 2.0 outputs, the two 2.5GbE RJ45 jacks, and the DC-in barrel connector. Cooling is active rather than fanless, using a heatpipe and a single fan that GMKtec tunes for quiet running, and the chassis exposes both memory and storage for easy servicing.
At the heart of the system sits the AMD Ryzen Embedded R2514, a four-core, eight-thread part with a 2.1 GHz base and 3.7 GHz boost, paired with an eight-core Radeon (Vega 8) integrated GPU clocked at 1200 MHz. This is the same Zen+ Picasso silicon family as the Ryzen 5 3500U, validated by AMD for embedded, always-on deployment. Reviewing the G11, Lon Seidman benchmarked its CPU at roughly the level of the budget Intel N150 and N300 parts common in mini PCs at this price, with slightly stronger graphics. He found it "performs well for the price point" for browsing and office work but was blunt about its ceiling, noting "It's definitely not going to be a gaming powerhouse" and that "this is not something that's going to run any current games very well." Buyers who want frame rates or heavy multitasking headroom should look at a newer Ryzen or a discrete-GPU box instead.
Connectivity is where the G11 earns its keep. WiFi 6E through a MediaTek RZ616 module and Bluetooth 5.2 handle wireless, while the two 2.5 Gigabit Ethernet ports make the machine a natural fit for pfSense or OPNsense routing, a home NAS, or a small virtualization host. Storage expansion runs through two M.2 2280 PCIe 3.0 slots supporting up to 16TB combined, and memory sits in two DDR4-2666 SO-DIMM slots that top out at 32GB. The single caveat on the ports is that the USB-C connector does data and DisplayPort output only; it will not power the unit over Power Delivery, so you are tied to the barrel adapter.
Reviewer Insights on the GMKtec G11
Lon Seidman (Lon.TV)
Lon Seidman reviewed the G11 in both a video and a companion written post, framing it as a rare affordable option in a market where budget mini PCs have crept upward in price. His hardware walkthrough covered the dual NVMe slots, the DDR4 SO-DIMM upgrade path, and the swappable WiFi card, and his testing confirmed the dual 2.5GbE ports and strong WiFi 6E throughput. On power and thermals he measured that the system "draws about 11 to 12 watts at idle and peaks at 48 watts under heavy load," staying quiet in its default modes.
Seidman was candid about the machine's limits. He saw dropped frames during 4K 60fps YouTube playback and rated its graphics too weak for modern gaming or heavy emulation, but he praised its behavior under Linux, saying "Linux seems to run a little more efficiently than Windows does these days, and it was a very good experience." His sharpest warning was about the software the unit ships with: he flagged pre-installed Chinese AI and system utilities and advised that "Given the low-level system access these types of AI tools often require, I would suggest that users consider a fresh installation of Windows or a move to a Linux distribution upon receiving the device." His overall read was positive on value with eyes open, summarizing that "it's good to see something affordable in the current state of the market."
Conclusion
The GMKtec G11 makes the most sense for buyers who value connectivity and uptime over processing power. Its dual 2.5GbE ports, WiFi 6E, dual M.2 slots, and triple 4K output give it a networking and expansion profile that punches above its class, and the embedded R2514 sips power while running quietly around the clock. As a home-lab router, a small NAS, a Plex-adjacent media box for standard-definition and 1080p content, or a tidy office desktop for web and document work, it does the job for less than most alternatives.
The tradeoffs are real. The R2514 is old, low-clocked silicon that struggles with 4K video playback, modern gaming, and 4K HDR transcoding, the USB-C port cannot power the unit, and the pre-installed software is worth wiping before you trust the machine with anything. Anyone who needs a faster CPU, more than 32GB of RAM, PCIe 4.0 storage, or USB4 should step up to a newer Ryzen or Intel box. For those comparing options, Starry Hope's Mini PC Comparison Chart helps line the G11 up against its peers.
Frequently Asked Questions
What processor does the GMKtec G11 use?
The G11 uses the AMD Ryzen Embedded R2514, a quad-core, eight-thread chip with a 2.1 GHz base clock and up to 3.7 GHz boost, plus an eight-core Radeon (Vega 8) integrated GPU at 1200 MHz. It is Zen+ silicon from the same family as the Ryzen 5 3500U, validated by AMD for continuous 24/7 embedded operation. In testing, Lon Seidman benchmarked its CPU at roughly the level of the budget Intel N150 and N300 parts common in this price bracket, with slightly better integrated graphics.
Can I upgrade the RAM and storage in the GMKtec G11?
Yes. The G11 has two DDR4 SO-DIMM slots that accept up to 32GB total at DDR4-2666, and two M.2 2280 PCIe 3.0 slots that support up to 16TB of NVMe storage combined. Both memory and storage are user-accessible, so you can add drives or swap RAM after purchase.
What ports does the GMKtec G11 have?
The front panel has one USB-C port (10Gbps data and DisplayPort output, but no Power Delivery input), two USB 3.2 Gen 2 Type-A ports at 10Gbps, and a 3.5mm combo audio jack. The rear adds two USB 3.2 Gen 1 Type-A ports at 5Gbps, two HDMI 2.0 outputs, two 2.5GbE RJ45 LAN ports, and the DC-in jack. Together the two HDMI ports and the USB-C output can drive three independent 4K displays.
Is the GMKtec G11 good for a home server or router?
It is a strong fit for that role. The two 2.5 Gigabit Ethernet ports let it act as a pfSense or OPNsense router or firewall, a fast NAS, or a small virtualization host, and its low idle power draw near 11 to 12 watts suits always-on duty. The R2514 is validated for 24/7 operation, though its modest CPU means heavy simultaneous workloads are better handled by a more powerful machine.
Does the GMKtec G11 run Linux well?
Yes. In his review, Lon Seidman reported that Linux ran efficiently on the G11 with a very good overall experience, and the AMD CPU and Radeon graphics have strong open-source driver support. Given that the unit ships with pre-installed Chinese AI and system utilities, Seidman suggests a clean Windows install or a switch to Linux once the machine arrives.
Can the GMKtec G11 handle gaming or 4K video?
Gaming is not its strength. Lon Seidman found the Radeon (Vega 8) graphics too weak for modern titles and demanding emulation, and the G11 dropped frames during 4K 60fps YouTube playback and struggled with 4K HDR Plex transcoding. It handles 1080p video, browsing, and office work comfortably, but 4K media and current games are beyond its comfort zone.
