Spec-sheet schematic of GMKtec EVO-X2 128GB - Ryzen AI Max+ 395 chip, 128GB unified memory, 256 GB/s
Overview

Three desktops on AMD’s Ryzen AI Max+ 395 (“Strix Halo”): the GMKtec EVO-X2 ($1,999, 2025), the Framework Desktop ($1,999, 2025), and the AMD Ryzen AI Halo reference box ($3,999, 2026). All three share the chip’s specs - 128GB unified LPDDR5X at 256 GB/s, 120W, Radeon 8060S graphics - and differ in enclosure, cooling, and warranty.

What it does well:

  • 128GB at $1,999: half the DGX Spark’s price for the same capacity, if you accept 256 vs 273 GB/s.
  • x86 compatibility: full ROCm and Vulkan runtimes, no ARM translation layer for exotic wheels or CUDA-alternative tooling.

Where it falls short: 256 GB/s is the ceiling, so single-stream decode trails NVIDIA discrete cards by a wide margin; ROCm support for consumer-class APUs has trailed CUDA in every runtime.

Run it locally: Ollama and LM Studio (Vulkan), llama.cpp with ROCm. The modeldex results rank checkpoints by fit and estimated tok/s - memory fit is identical across all three enclosures.
