GMKtec will open early access registration for the EVO-X3 mini PC on June 22, 2026, a week ahead of its global launch on June 29. The compact system, first teased earlier this year, crams AMD’s Ryzen AI Max+ 395 processor, up to 128GB of memory, and OCuLink Gen 4 connectivity into a chassis the size of a small book. For Windows power users chasing local AI inference, computational workloads, or a clutter-free desktop, the EVO-X3 packs an impressive punch in a minimal footprint.

The timing is no accident. With Microsoft pushing Copilot+ PC experiences and on-device AI capabilities, a mini PC purpose-built around AMD’s highest-end mobile APU positions GMKtec as a contender in the emerging category of AI-ready workstations. Early adopters will need to register quickly — GMKtec has not disclosed unit allocations, but previous early access programs from the brand have sold out within hours.

Under the Hood: AMD Ryzen AI Max+ 395 and Unified Memory

At the core of the EVO-X3 sits the AMD Ryzen AI Max+ 395, a monolithic die that combines Zen 5 CPU cores, RDNA 3.5 graphics, and an XDNA 2 neural processing unit (NPU). While GMKtec has not published the exact core configuration, industry leaks pin the Max+ 395 as a 16-core/32-thread part with a boost clock exceeding 5.0 GHz. The NPU alone delivers up to 50 TOPS of INT8 performance, meeting and surpassing Microsoft’s 45 TOPS threshold for next-generation AI features in Windows 11.

Paired with the processor is up to 128 GB of LPDDR5X-8533 unified memory. This shared memory architecture allows both the CPU and integrated GPU to access the same pool of high-bandwidth memory, accelerating tasks like large language model inference, 3D rendering, and video encoding without the bottlenecks of discrete graphics memory. In synthetic benchmarks, the RDNA 3.5 iGPU should rival entry-level discrete GPUs, making the EVO-X3 capable of driving multiple 4K displays or handling moderate graphical workloads natively.

Perhaps the most intriguing design choice is the inclusion of OCuLink Gen 4. Unlike Thunderbolt or USB4, OCuLink offers a pure PCIe 4.0 x4 connection with no encapsulation overhead, delivering a true 64 Gbps of bandwidth. This makes external GPU docks far more viable than over USB4, where data encapsulation typically cuts usable throughput by 20-25%. GMKtec has positioned the EVO-X3 as a workstation that can scale: connect a full-size desktop GPU via an OCuLink dock, and the mini PC transforms into a capable CUDA or ROCm development rig for deep learning or 3D modeling.

The port also supports external NVMe enclosures, enabling rapid project transfers or backup workflows. GMKtec hints that multiple OCuLink docks will be validated at launch, though exact models remain unannounced.

Cooling and Build: Designed for Sustained Performance

Mini PCs of this caliber often struggle with thermal throttling. The EVO-X3 reportedly employs a vapor chamber and dual high-speed fans, a design borrowed from gaming laptops but scaled for a desktop tower. Early leaked renders show extensive venting on the sides and bottom, suggesting active airflow across both the SoC and memory. GMKtec claims the system can maintain a 65W TDP indefinitely without throttling, though independent testing will be necessary to verify that.

The chassis itself is constructed from machined aluminum, with a matte black finish and subtle RGB accent lighting. Front I/O includes USB4, two USB 3.2 Gen 2 ports, and a combo audio jack, while the rear houses OCuLink, 2.5Gb Ethernet, DisplayPort 2.1, HDMI 2.1, and additional USB ports. WiFi 7 and Bluetooth 5.4 are standard.

Windows 11 Pro and AI Integration

The EVO-X3 ships with Windows 11 Pro pre-installed, taking full advantage of AMD’s Ryzen AI engine. While GMKtec stops short of calling it a “Copilot+ PC” — that certification currently requires a dedicated Copilot key and specific OEM firmware — the NPU nevertheless accelerates Windows Studio Effects, real-time video upscaling, and any ONNX runtime workloads. Developers can tap the NPU directly via DirectML or AMD’s ROCm stack for AI model fine-tuning, LLM inference with frameworks like Llama.cpp, or Stable Diffusion image generation.

The mini PC also supports Windows Subsystem for Linux (WSL2) with GPU passthrough via the iGPU, making it a capable platform for cross-platform AI development. For IT departments, the combination of AMD Ryzen PRO manageability features (if present on the Max+ 395) and Windows 11’s security stack — virtualization-based security, credential guard, and TPM 2.0 — could make the EVO-X3 an attractive node in secure enterprise deployments.

Memory and Storage Configurations

GMKtec plans to offer multiple configurations, though the early access units will focus on the top-tier 128 GB variant. The unified memory pool is likely split: a portion acts as standard system RAM, while the remainder can be allocated as dedicated VRAM for the iGPU. In the BIOS, users can adjust this split, with a maximum of 16 GB reserved for graphics on the 128 GB model.

Storage options include two M.2 2280 PCIe 4.0 x4 slots. GMKtec may offer pre-configured NVMe SSDs up to 2 TB, with user-upgradeable access behind a bottom panel. Early adopters should note that while the OCuLink port can host an external drive, internal storage expansion is limited to the two M.2 slots — there is no SATA interface.

Use Cases: Who Is the EVO-X3 For?

The EVO-X3 isn’t for casual browsing or media streaming. Its processor, memory density, and expansion target specific audiences:

  • AI/ML Developers and Data Scientists: Run local LLMs like Llama 3 or Code Llama entirely in RAM without GPU clouds. The NPU offloads matrix multiplications, freeing the CPU for data preprocessing.
  • Content Creators: 3D artists and video editors can render in Blender or DaVinci Resolve using the iGPU, then dock an external GPU for final exports. 128 GB of memory accommodates massive After Effects compositions.
  • Software Engineers: The EVO-X3 can serve as a headless CI/CD build server or Kubernetes node, with OCuLink providing fast storage for container images.
  • Home Lab Enthusiasts: Run multiple virtual machines under Hyper-V or VMware Workstation; the generous memory allows several 16 GB VMs simultaneously.
  • Gamers with Flexibility: While not a gaming rig out of the box, the OCuLink port lets users attach a desktop RTX 4070 or 4080 for 1440p gaming at high refresh rates, effectively turning the mini PC into a modular console.

Launch Details and Early Access

Registration for early access opens at 9:00 AM EDT on June 22, 2026, on GMKtec’s official website. Only registered users will receive a unique purchase link for the June 29 global launch. GMKtec has warned that quantities are strictly limited, and each account may be restricted to one unit. Pricing remains undisclosed, but given the premium hardware — comparable to a high-end laptop without the display and battery — expect a starting price around $1,500 for the base 32 GB configuration, scaling to $2,200 or more for the 128 GB flagship.

Early buyers will receive a 10% discount and a free GMKtec branded 240W GaN charger, based on past promotions. The company also promises a three-year warranty, rare in the mini PC segment.

Competition and Market Context

The EVO-X3 enters a market that has seen rapid evolution. Intel’s NUC 13 Extreme kits offer socketed desktop CPUs but in a larger form factor and without an NPU. ASUS’s ROG NUC pairs Intel Core Ultra processors with mobile RTX GPUs, but at a premium and lacking OCuLink. Smaller vendors like Minisforum have teased products with AMD’s Ryzen AI 9 HX 370, but none match the Max+ 395’s unified memory capacity and high-speed expansion. The EVO-X3’s combo of top-tier NPU, massive memory, and pure PCIe tethering carves a niche currently unoccupied.

For Windows AI workloads specifically, Microsoft’s Surface Pro 10 and Laptop 6 for Business use Intel’s Core Ultra with NPUs but cap memory at 64 GB. The Ryzen AI Max+ 395 in a desktop form factor with 128 GB of unified memory transcends laptop constraints, enabling models that simply won’t fit elsewhere.

Initial Impressions and Caveats

While the specs impress, several unknowns linger. Thermal performance under sustained all-core loads remains unverified; 65W TDP in a tiny chassis requires robust cooling. The OCuLink ecosystem, while growing, still lacks the plug-and-play maturity of Thunderbolt. Finally, AMD’s Ryzen AI software stack is less mature than NVIDIA’s CUDA, so developers may encounter rough edges when targeting the NPU.

Despite these uncertainties, GMKtec’s track record with previous Ryzen-powered mini PCs gives reason for optimism. The company has consistently delivered well-constructed, quiet systems that hold their own in benchmarks. The EVO-X3 looks to extend that reputation into the AI workstation category, offering Windows users a rare combination of compact size and unbridled memory bandwidth.

What to Expect on June 22

Prospective buyers should have their GMKtec account created in advance and be ready to refresh the product page promptly. The registration process requires only an email address, but completing a brief survey on intended use cases may improve selection odds. GMKtec has hinted that surveys help prioritize infrastructure developers and researchers, aligning with the product’s professional orientation. Successful registrants will receive a confirmation email with the purchase link on June 28.

As the mini PC landscape heats up, the EVO-X3 stands as GMKtec’s most ambitious product yet. Its success could push other manufacturers to adopt OCuLink more widely and accelerate the integration of high-performance NPUs into compact desktops. For now, all eyes are on June 22.
