Google Reuses Silicon, Ships Four Systems
Two new configurations target confidential computing and long-context serving without new chips.
Google Cloud announced TPU 8tx and TPU 8i Max on 9 November 2026, its fourth TPU system of the year after TPU 8t and TPU 8i in April. TPU 8tx reuses 8t silicon with a fifth-generation AMD EPYC host processor and a low-latency network, becoming the first TPU with confidential computing, with latency up to half that of 8t. TPU 8i Max packages two 8i chips, lifting memory bandwidth to 17.2TB/s while HBM capacity rises about 33% to 384GB. No pricing or availability date was disclosed.
