Apple A20 Pro's 50% memory bandwidth jump is a big deal for on-device multi-agent AI
Scobleizer · x · 2026-09-10
Reports say Apple's new A20 Pro has 50% more memory bandwidth than its predecessor. The author argues this is a pivotal hardware move for on-device multi-agent systems (e.g., clinician scribe/coding/guideline/referral agents) that share patient context, tool results, and memory concurrently. Narrow bandwidth means sluggish orchestration, truncated context, and data pushed to the cloud "just this once" — how sovereignty dies in healthcare. On-device AI is limited by how fast weights, activations, and KV cache move.
