My latest mini PC review takes a look at the GMKtec M8, a mid-range mini PC that sits comfortably between entry-level systems and higher-end compact desktops. It’s built around AMD’s older Ryzen 5 6650H, a six-core, twelve-thread processor, paired with 16 GB of DDR5 memory and a 512 GB NVMe SSD. On paper, it’s not cutting-edge hardware, but in practice it feels capable enough for most everyday workloads without calling too much attention to its limitations m8.
Check it out in my latest video review.
What stood out immediately was the port selection, especially given the price point, which was quite reasonable when I recorded the video. You can see current pricing over at Amazon (compensated affiliate link).
On the front, GMKtec includes both an OcuLink port and a 40 Gbit-per-second Thunderbolt compatible USB 4 port. OcuLink is still relatively uncommon on systems in this price category, but it opens the door to directly attaching PCI Express devices like external GPUs with less overhead than Thunderbolt.
The USB4 port performed as expected when I tested it with an external Thunderbolt SSD, delivering transfer speeds consistent with a full-bandwidth implementation. Alongside those are two USB-A ports, a combined headphone and microphone jack, and the power button. Around back, there’s another mix of USB ports, HDMI and DisplayPort outputs, and dual 2.5-gigabit Ethernet connections.
Display support was solid in my testing. While GMK advertises support for up to three 8K displays, I don’t have an 8K panel on hand. With multiple 4K displays connected, everything worked as expected through HDMI, DisplayPort, and the USB 4 port via a dongle. Networking performance was also better than I usually see on small PCs. Both Ethernet ports hit their rated speeds, and the Wi-Fi 6E adapter delivered strong throughput, including upstream speeds that cleared a gigabit on my network.
Internally, there are some tradeoffs. The 16 GB of DDR5 memory is soldered, so RAM upgrades aren’t an option. Storage, however, is more flexible. After unscrewing the rubber feet and opening the case, I was able to access the Wi-Fi card and space for two NVMe drives, which makes dual-boot setups feasible.
Out of the box, the system ships with Windows 11 Pro pre-installed. The operating system comes activated with a proper license.
For basic use, the M8 behaved the way I’d expect a six-core Ryzen 6000 series processor to behave. Web browsing at 4K60 felt responsive, with smooth scrolling and no obvious slowdowns. Media playback was similarly uneventful in a good way, with only the occasional dropped frame during Youtube 4K60 playback, nothing I would have noticed without looking for it with the “stats for nerds” diagnostics screen enabled. Benchmark testing put it in line with other systems in this price range with similar processors.
Light video editing was workable as well. Simple 4K timelines with basic transitions played back reasonably smoothly, though this is not the kind of machine I’d recommend for heavy editing without adding an external GPU. That option is there, though, and connecting one through OCuLink or USB4 would dramatically change what the system is capable of doing.
Gaming is where expectations need to be managed. Modern, demanding titles like Cyberpunk 2077 are playable, but only at low settings. At 1080p, performance hovered around 30 frames per second, with better results at 720p, where frame rates climbed into the mid-40s and occasionally higher in less complex scenes. In that sense, the experience reminded me a bit of a Steam Deck connected to a monitor. Emulation, on the other hand, was a strong point. PlayStation 2 emulation at native resolution ran at full speed, and older systems performed without issue.
Thermally, the system held up well under sustained load, passing stress tests without significant throttling. The fan is audible in performance mode, which runs the processor at its full 40-watt envelope, but it’s not among the loudest mini PCs I’ve tested. BIOS options allow you to dial things back with balanced and quiet modes if noise is a concern, trading off some performance in exchange for lower fan activity.
I also spent some time with Linux, booting a recent Ubuntu release. Hardware detection was smooth across the board, including Wi-Fi, Bluetooth, audio, and networking, which suggests the M8 would be a comfortable choice for Linux users or anyone planning a dual-boot setup.
Taken as a whole, the GMK M8 feels like a system built around practical choices. You give up upgradeable memory, but for a reasonable price you get unusually fast I/O for the class, solid networking, and performance that’s adequate for everything from everyday computing to light creative work and emulation.
