Strix Halo, DGX Spark disrupt local LLM hardware

As local LLM hardware shifts toward unified memory, AMD’s Strix Halo and NVIDIA’s DGX Spark emerge as the new standard for "moderate" spenders. These 128GB unified systems finally make 70B+ models accessible without the complexity and power draw of multi-GPU arrays.

// ANALYSIS

The era of "used 3090 arrays" is fading as unified memory APUs and "personal AI appliances" hit the $2k-$5k sweet spot.

–AMD Strix Halo (Ryzen AI Max+) provides the best price-per-GB for unified memory, enabling 70B models in compact, power-efficient form factors.
–NVIDIA DGX Spark brings the Grace Blackwell superchip to a professional workstation tier, offering a "mini-supercomputer" experience with superior CUDA stability.
–Intel's Arc Pro B70 is a dark horse for multi-GPU builds, offering 32GB of VRAM for under $1,000, though software support remains a hurdle.
–The RTX 5090's 32GB limit is increasingly a bottleneck for researchers who value model parameter count over raw tokens-per-second throughput.
–MacBook Pro M5 Max remains the "luxury" choice, offering the most polished unified memory experience at a significant price premium.
