GMKtec EVO-X3 Mini PC Adds OCuLink, WiFi 7, and a Future 192GB Ryzen AI MAX+ 495 Model

GMKtec is preparing the EVO-X3, a new mini PC that builds on last year’s EVO-X2 with upgraded connectivity, stronger expansion options, and a future configuration that will push unified memory capacity much higher. The system was shown at Computex 2026 as a follow up to the EVO-X2, which used AMD’s Ryzen AI MAX+ 395 chip and positioned itself as a lower cost alternative to NVIDIA’s DGX Spark style developer systems.

The first EVO-X3 model will continue with the AMD Ryzen AI MAX+ 395, but GMKtec is making several important changes around the chip. The most notable upgrade is OCuLink support. That port allows the mini PC to connect to an external discrete graphics card with much better bandwidth than typical USB4 based eGPU setups. For buyers who want a compact system but still need stronger graphics performance later, OCuLink could be the feature that makes the EVO-X3 more flexible than its predecessor.

The system will also include WiFi 7, USB4 ports, and dual PCIe 4.0 drive bays for storage. The reference configuration is expected to ship with 2TB of storage, while 128GB of memory will come standard on the Ryzen AI MAX+ 395 version.

GMKtec is using a taller design to improve cooling and expansion

The EVO-X3 is taller than the EVO-X2, but also slimmer. That change is not only about looks. The taller chassis gives GMKtec more room for cooling, including larger fans and exhaust vents. That matters because AMD’s Ryzen AI MAX chips combine CPU, GPU, and AI focused performance in a compact package, which can create serious thermal demands when pushed hard.

A larger cooling system may help the EVO-X3 sustain higher performance for longer workloads. That could make it more useful for local AI work, compact workstation tasks, content creation, software development, and high memory productivity workloads.

A Ryzen AI MAX+ 495 model with 192GB memory is planned for later

The more interesting version may arrive later this year. GMKtec said it is also working on an EVO-X3 model with AMD’s Ryzen AI MAX+ 495 and 192GB of LPDDR5X memory. That version should sit above the Ryzen AI MAX+ 395 model and target buyers who need more memory for large AI models and other heavy workloads.

The 192GB memory configuration is especially important because these Ryzen AI MAX systems use unified memory. GMKtec says the 495 model can offer up to 160GB of unified memory for the GPU. That could make the system useful for running larger local AI models, experimenting with AI development, or handling graphics and compute tasks that need much more memory than most compact PCs can provide.

Pricing has not been confirmed yet. The Ryzen AI MAX+ 495 model will almost certainly cost more than the 395 version because of the newer chip and larger memory configuration. The EVO-X3 with Ryzen AI MAX+ 395 is expected to arrive soon, while the 495 model is planned for later this year.

GMKtec’s EVO-X3 shows how quickly the mini PC market is changing. These systems are no longer only small office desktops or media machines. With Ryzen AI MAX chips, OCuLink, WiFi 7, dual PCIe 4.0 storage, and up to 192GB of memory, the EVO-X3 is moving closer to compact AI workstation territory while still keeping the footprint far smaller than a traditional desktop.
