Hot Chips 2026: Arm Details AGI Server CPU With Two 70-Core N3P Chiplets
Tom's Hardware, Wednesday, August 26th, 2026
Arm disclosed its AGI server CPU design at Hot Chips 2026: two 70-core N3P chiplets linked by a 2 TB/s UCIe fabric.
Tom's Hardware's Hot Chips 2026 coverage details Arm's AGI data-center CPU, built from two 70-core chiplets fabricated on TSMC's N3P process and connected via a 2 TB/s UCIe die-to-die fabric link.
The design includes a 12-channel memory controller aimed at feeding large-core-count workloads with sufficient bandwidth for AI and data-center applications.
The disclosure gives architects and system builders concrete details on Arm's chiplet interconnect and memory subsystem choices as it competes for a slice of the growing AI server CPU market alongside Nvidia and traditional x86 vendors.
