Local AI Hardware in 2026: Why Unified Memory Outperforms Discrete RTX 5090 & 5080 for LLMs (NVIDIA DGX Spark GB10, Surface Dev Box, M5 Mac Studio & PAIR Ecosystem)
A rigorous technical and economic breakdown of 2026 local AI hardware: the global GDDR7 shortage impact on pricing, the massive architectural shift toward high unified memory (NVIDIA DGX Spark on GB10, Microsoft Surface RTX Spark Dev Box, Apple Mac Studio M5, AMD Strix Halo 128GB) versus discrete RTX 5090/5080. Detailed benchmarks across the NVIDIA PAIR ecosystem, media generation (Wan 2.2, Flux) and 70B+ LLM reasoning (DeepSeek R1, Qwen 2.5).
