Google has reportedly tasked Marvell with designing a dedicated networking chip to pair with its upcoming TPUv8e accelerators. The design intends to link TPU clusters, coordinate data flow, and reduce latency across sprawling AI data-center deployments. The chip is expected to leverage Intel's advanced 18A/18AP lithography, addressing current bottlenecks at TSMC that complicate the fabrication of next‑gen AI hardware. Intel would handle fabrication and EMIB-based packaging, with MediaTek involved in I/O and back-end design. Production for the networking chip is anticipated by the end of 2027, aligning with the roll-out of the Humufish TPUv8e main die. Google already operates TPU clusters across 11 data-center regions and two AI zones, underscoring the critical need for scalable interconnects. The collaboration also marks a notable win for Marvell, bolstered by praise from Nvidia’s CEO regarding the company’s trajectory.
A dedicated networking chip for Google's TPUv8e will be designed by Marvell and fabricated on Intel’s 18A/18AP process, with EMIB packaging and integration with the TPUv8e stack, set for 2027 production.
