Summary
With DGX Spark prices climbing and some users linking multiple units just to fit large models, Alex Ziskind asks whether a single mini PC can do the job for roughly half the money. He tests the GMK Tech Evo X5 Pro, a $7,000 machine with 192 GB of unified memory built around AMD’s Ryzen AI Max Plus Pro 495 (Gorgon Halo) chip, against NVIDIA’s DGX Spark.
The video starts with the hardware as it ships and the memory limits that come with it. It then covers CPU results, where the GMK’s x86 cores finish a Linux kernel build in 54 seconds versus 66 on the Spark, and memory bandwidth, which is nearly identical at about 246 versus 248 GB/s measured on the GPU.
The main test is running models too large for one Spark. After raising the GPU memory allocation to 160 GB in the BIOS, GLM 5.3 (157 GB), DeepSeek V4 Flash and Qwen 3 235B all load and run at roughly 14 to 16 tokens per second. The video also walks through a ComfyUI slowdown on Linux with ROCm, fixed with a one-line change, and compares Windows, Linux, Vulkan and ROCm results along with multi-agent coding workloads.
