Google's Most Powerful Supercomputer Ever Has A Combined Memory Of 1.77PB - Apparently A New World Record For Shared Memory Multi-CPU Setups
Google, Thursday, September 4th, 2025
Ironwood TPU is already deployed in Google Cloud data centers
Google closed out the machine learning sessions at the recent Hot Chips 2025 event with a detailed look at its newest tensor processing unit, Ironwood.
The chip, which was first revealed at Google Cloud Next 25 back in April 2025, is the company's first TPU designed primarily for large scale inference workloads, rather than training, and arrives as its seventh generation of TPU hardware.
Each Ironwood chip integrates two compute dies, delivering 4,614 TFLOPs of FP8 performance - and eight stacks of HBM3e provide 192GB of memory capacity per chip, paired with 7.3TB/s bandwidth.
