Local AI hardware 2026 has 3 main contenders: NVIDIA RTX Spark, AMD Strix Halo 395, and Apple M5 Max/Ultra. Each has different memory bandwidth, inference speed, and price. Users are confused which on
Bandwidth = inference speed (this is the key insight). Test on 70B LLM:
- M5 Max: 614 GB/s → 17.5 tokens/s
- RTX Spark: 273 GB/s → 7.8 tokens/s
- AMD 395: 215 GB/s → 6.1 tokens/s
Price positioning:
- AMD 395: $4,699 (1/3 of DGX Spark)
- M5 Max/Ultra: premium tier
- RTX Spark (DGX): $1,500 entry
Differentiator:
- RTX Spark: only option with 3A gaming + AI Agent + 8K video (RTX 5070 level, DLSS 4.5, NVFP4)
- AMD 395: x86 standard architecture, 55-85W low power, 128GB full
- M5 Max/Ultra: bandwidth ceiling, best for large models
