Google Unveils TPU 8tx and TPU 8i Max AI Chips to Challenge Nvidia

Google introduced two eighth-generation custom AI processors, the TPU 8tx and TPU 8i Max, scheduled for availability in 2027. Developed with Broadcom, the chips target secure computing for regulated industries and memory-intensive agentic AI workloads. AMD announced its fifth-generation EPYC processors will power the host infrastructure for the TPU 8tx, establishing the first cloud TPU system with hardware-enforced confidential computing. The processors reportedly cost roughly 30% less than comparable Nvidia GPUs. Following the announcements, Alphabet shares rose up to 4% intraday, while Nvidia shares dropped over 4% amid heightened competition and executive scrutiny.
