Google Cloud introduced two new Tensor Processing Unit (TPU) chips, TPU 8tx and TPU 8i Max, expanding its eighth-generation family. These chips are designed for secure AI workloads and higher-capacity inference in enterprise applications. Google has announced TPU 8tx for confidential inference and TPU 8i Max, which packages two 8i chips together. We check what the "2x" figures are measured against, how the software tests were run on.
