Ironwood: The first Google TPU for the age of inference (blog.google)

Article summary

Google has introduced Ironwood, its seventh-generation Tensor Processing Unit (TPU), designed specifically for inference and capable of handling large language models and mixture of experts. Ironwood scales up to 9,216 chips, offering 42.5 Exaflops of compute power. It is built to support the 'age of inference' where AI agents will proactively retrieve and generate data to collaboratively deliver insights and answers. Ironwood is part of Google Cloud AI Hypercomputer architecture, which optimizes hardware and software for demanding AI workloads.

What commenters say

• The comparison of Ironwood's performance to El Capitan is misleading and unnecessary, as it does not account for differences in architecture and usage.
• The focus on fp8 performance is justified because it is the relevant metric for many AI workloads, and users care about speed rather than architectural details.
• Google's marketing strategy is driven by the need to impress potential customers and investors, even if it means presenting misleading comparisons.
• The TPU's design and capabilities make it less suitable for tasks other than matrix multiplications, limiting its potential applications beyond AI inference.
• The introduction of Ironwood is a significant development in the AI hardware space, potentially challenging Nvidia's dominance and shaking up the market.
• The distinction between training and inference workloads is important, with some arguing that inference will become the primary focus in the long run, while others believe that training will remain a significant portion of the work.
