What AI models can the AMD Ryzen AI 9 HX 470 (DDR5 SO-DIMM) (128 GB) run?

Unified memory
128 GB
Usable for models
96.0 GB
Memory bandwidth
90 GB/s
FP16 compute
25.4 TFLOPS
Released
2026

macOS lets the GPU use roughly two-thirds to three-quarters of unified memory by default, so we plan around that figure rather than the full 128 GB.
