Google adds TPU 8i Max and TPU 8tx to its eighth-generation TPU lineup
TPU 8tx pairs an eighth-gen TPU with an AMD EPYC CPU host and targets government and financial workloads; pricing was not disclosed.
Google announced two additions to its eighth-generation TPU lineup, the TPU 8i Max and TPU 8tx, on its official blog on November 9 local time, according to aitimes.com. Both systems reuse the company's existing eighth-generation TPU chips with different packaging, memory, network and security configurations rather than introducing new semiconductor designs.
The TPU 8i Max combines two existing TPU 8i chips in a single package, doubling compute performance, SRAM capacity and HBM bandwidth. TPU 8i was originally introduced for real-time inference workloads.
The TPU 8tx pairs the same chip used in the TPU 8t with an AMD fifth-generation EPYC CPU host and is designed to protect data and model weights at the hardware level. Google says the system offers up to twice lower latency than the TPU 8t with almost no performance loss. It is aimed at organizations handling sensitive data and running their own AI models, such as government agencies and financial companies.
Google has roughly 100 TPU customers, including AI model developers, financial companies, retailers and universities. The company did not disclose pricing for the new products or performance figures against Nvidia's competing products under identical conditions.
Earlier eighth-generation releases
In April 2026, Google unveiled the TPU 8t for large-scale AI model training and the TPU 8i for real-time inference. Last month it released the open-source tool TorchTPU, which lets PyTorch code run on TPUs without separate modifications. In its third-quarter earnings, Google said TPU sales made a meaningful contribution to results, with Google Cloud revenue of $30.71 billion, more than double the same period a year earlier.
Quick answers
What is the difference between the TPU 8i Max and TPU 8tx?
TPU 8i Max combines two TPU 8i chips in one package to double compute, SRAM and HBM bandwidth, while TPU 8tx pairs a TPU 8t-class chip with an AMD fifth-generation EPYC CPU host and adds hardware-level protection for data and model weights.
How much do the new Google TPUs cost?
Google did not disclose pricing for the TPU 8i Max or TPU 8tx.
Who is the TPU 8tx designed for?
It targets organizations that handle sensitive data and their own AI models, such as government agencies and financial companies.
