Revealed at Google Cloud Next 2026 , the upgrades focus on longer context windows, multi-step reasoning and responsiveness at scale, thus its cloud infrastructure is being rebuilt to support persistent memory, continuous inference and multi-model workloads. This year, we're seeing two distinct
TPUs designed to support massive HBM scaling, with Google Cloud placing an emphasis on memory bandwidth as much as compute.

With around an 80% year-over-year improvement in performance per dollar, the company says it will train trillion-parameter models more efficiently.

Google Cloud explained that a single TPU 8t superpod can scale up to 9,600 chips, delivering 2PB of shared HBM and 121 ExaFlops of compute. For comparison, last year Ironwood was rated at up to 9,216 chips in a superpod and 42.5 ExaFlops.

Google Cloud also warned of "the latency wall" we face in an always-on
agentic era, hence the launch of 8i, a second chip which serves as a post-training and inference engine.

TPU 8i sees around a 3x increase in on-chip SRAM to 384MB as well as 288GB of HBM, with pod size now up to 1,152 chips from 256, delivering 11.6 ExaFlops
of performance (up from 1.2 ExaFlops). Are you a pro? Subscribe to our newsletter Sign up to the TechRadar Pro newsletter to get all the top news, opinion, features and guidance your business needs to succeed! Contact me

As for energy and thermal efficiency, Google Cloud boasts of up to 2x better performance-per-watt over Ironwood, the predecessor.

"We['ve] innovated across hardware and software to enable our data centers to deliver six times more computing power per unit of electricity than they did just five years ago," SVP and Chief Technologist for AI and Infrastructure Amin Vahdat explained.

General availability for Google Cloud customers is expected in the coming months, and naturally, TPU 8t and TPU 8i will be at the forefront of the latest Gemini models.

The company also sees the eighth-gen hardware playing a role in developing
the next frontier models by distributing training beyond a single superpod using Pathways and JAX to unlock scaling beyond one million TPU chips per any single training cluster something execs confirmed at the event is currently entirely theoretical (but technically possible), with the TPUs yet to be made available at such a scale.
