I recently received the new GMKTec K15, marking my first mini PC review of 2026. If I had to characterize this device with a single analogy, I would describe it as the Toyota Camry of its category: It is neither a stripped-down budget device nor a high-end powerhouse; rather, it occupies a functional middle ground.

See it in action in my latest review!
The system is built around the Intel Core Ultra 125U processor from the Meteor Lake family. This chip features a 12-core architecture—comprising two performance cores, eight efficiency cores, and two low-power efficiency cores—delivering a total of 14 threads. My unit arrived equipped with 32 GB of DDR5-4800 RAM and a 1 TB NVMe SSD. While the current price sits higher than it otherwise would due to the volatility of memory prices, if things do let up it should sell for less than its current price.
Despite the cost, the expandability is notable; the system supports up to 96 GB of RAM and features three NVMe slots, which is generous for a device of this footprint.
Connectivity is a strong suit for the K15. The front panel includes a 10Gbps USB-C port and three USB-A ports. The rear I/O offers 40 gigabit USB 4 port, which is Thunderbolt compatible, dual 2.5GbE Ethernet ports, and an Oculink port. The Oculink addition is particularly useful for those interested in external GPUs, as it connects directly to the PCIe bus, offering superior bandwidth compared to USB 4. During my tests, the Wi-Fi 6 chipset performed well, maintaining speeds close to gigabit levels, and the variety of ports suggests this unit could easily be repurposed as a home server.
In terms of daily performance, the K15 handles standard desktop workloads efficiently. Web navigation is snappy, and 4K video streaming presented no issues aside from the expected minor frame drops upon initial loading. Content creation capabilities, however, have a clear ceiling. When editing 4K video in DaVinci Resolve, simple cuts and transitions were smooth, but the system bogged down significantly when attempting complex color grading or heavy effects. It is serviceable for basic edits, but anything more demanding would necessitate an external graphics solution.
Gaming performance aligns with the limitations of the integrated graphics and the reduced GPU performance on this 125U processor vs. the higher end 125H. Testing Cyberpunk 2077 at 1080p with the lowest settings resulted in frame rates hovering between 25 and 30 frames per second. It’s certainly playable, but lagging behind some of the more higher end mini PCs. While it struggles with modern, graphically intensive titles, it is perfectly adequate for older games or emulation. Thermals were well-managed throughout these stress tests; the CPU temperature stayed around 43°C, and the fan noise was minimal, likely due to a larger fan design that moves air efficiently at lower RPMs.
The device arguably shines brightest when running Linux. My experience with the OS was seamless, with all hardware—including Wi-Fi and Bluetooth—detected immediately. The system felt more responsive on Linux than on Windows, which has become increasingly bloated. Between the stable performance, the quiet operation, and the extensive storage options, the K15 stands out as a sensible, if modest, choice for a reliable workstation.
