GMKtec EVO-X3 mini PC adds OCuLink port and prepares 192GB Ryzen AI MAX+ 495 variant

GMKtec EVO-X3 Brings OCuLink Support and Enhanced Connectivity

GMKtec has revealed the GMKtec EVO-X3, the follow-up to its well-received EVO-X2 mini PC, introducing significant connectivity upgrades while maintaining the same AMD Ryzen AI MAX+ 395 processor 1

1

. The most critical improvement in this iteration is the native OCuLink port, which provides substantially greater bandwidth than the USB4 ports found on the previous model 2

2

. This port enables users to connect external graphics cards with much faster eGPU support, addressing a key limitation of earlier designs. The EVO-X3 mini PC also features Wi-Fi 7 support, USB4 ports, and dual PCIe 4.0 storage drive bays, creating a comprehensive connectivity package for demanding workflows 1

Ryzen AI MAX+ 495 Variant with 192GB Memory Coming Later

While the base EVO-X3 launches with the same AMD Ryzen AI MAX+ 395 chip as the EVO-X2, GMKtec is preparing a more advanced variant featuring the Ryzen AI MAX+ 495 processor 1

1

. This upcoming configuration will include 192GB memory of LPDDR5X memory, a substantial upgrade from the 128GB standard in the base model 2

2

. That expanded memory pool enables up to 160GB of configurable VRAM through unified memory support for the GPU, allowing users to run significantly larger AI models locally 1

2

. AMD confirmed the Ryzen AI MAX PRO 400 series in May, with the chip remaining on Zen 5 CPU cores and RDNA 3.5 graphics, making it a clock-bumped refresh of the current Strix Halo platform rather than a new architecture 1

1

. The main upgrades include higher GPU clocks at 3.0GHz versus 2.9GHz and Radeon 8065S graphics.

Improved Thermal Performance and Design Changes

The physical design of the EVO-X3 differs notably from its predecessor, with the system being taller but slimmer than the EVO-X2 2

2

. This additional height allows GMKtec to incorporate larger fans and improved exhaust vents, providing better thermal performance and increased thermal headroom for sustained workloads 1

1

. The reference configuration will include 2TB of storage capacity, and the system will support ROCm software for AI development tasks 1

1

. Pricing has not been confirmed for either variant, though the 495 model is expected to retail at a higher price due to its larger memory configuration and upgraded processor 2

2

. The base EVO-X3 with the Ryzen AI MAX+ 395 is expected soon, while the 495 variant will arrive later in 2025 1
