Overview
- AMD published full specs for the Ryzen AI MAX 400 family on May 21, 2026, announcing three SKUs (Max+ Pro 495, Pro 490, Pro 485) built on Zen 5 CPU cores, RDNA 3.5 GPU cores, and an XDNA 2 NPU.
- The headline hardware change is support for up to 192 GB of unified memory, of which 32 GB is reserved for the system and up to 160 GB can be used as GPU/VRAM to accommodate very large LLMs.
- The flagship Max+ Pro 495 is rated with a 55 TOPS NPU, 16 CPU cores and a boost to 5.2 GHz, and the family has a configurable TDP range that scales up to 120 W for compact workstations.
- AMD will start Halo mini‑PC preorders in June for $3,999 with a first‑gen unit based on the earlier 395 SoC and says partner systems using the new 400‑series will appear from OEMs in Q3 2026.
- AMD supplied token‑per‑second and cost‑saving comparisons to NVIDIA’s DGX Spark and promoted ROCm software support, but those performance and economics claims are vendor‑provided and need independent validation before broad adoption.
