128 GB coherent unified memory. Check ARM64 runtime and checkpoint support. Capacity alone does not establish throughput or compatibility. manufacturer specification ↗.
Text models within the planning estimate
These are capacity candidates under a generic Q4 formula, not measured executions. The total estimate does not separately prove KV cache, vision encoder, runtime support or multi-GPU placement.
