TPUv7: Google Takes a Swing at the King
Evidence
Context After
The dawn of the AI era is here, and it is crucial to understand that the cost structure of AI-driven software deviates considerably from traditional software. Chip microarchitecture and system architecture play a vital role in the development and scalability of these innovative new forms of software. The hardware infrastructure on which AI software runs has a notably larger impact on Capex and Opex, and subsequently the gross margins, in contrast to earlier generations of software, where developer costs were relatively larger. Consequently, it is even more crucial to devote considerable attention to optimizing your AI infrastructure to be able to deploy AI software. Firms that have an advantage in infrastructure will also have an advantage in the ability to deploy and scale applications with AI.
Google had peddled the idea of building AI-specific infrastructure as far back as 2006, ↗ but the problem came to a boiling point in 2013. They realized they needed to double the number of datacenters they had if they wanted to deploy AI at any scale. As such, they started laying the groundwork for their TPU chips which were put into production in 2016. It’s interesting to compare this to Amazon, who in the same year, realized they needed to build custom silicon too. In 2013, they started the Nitro Program ↗, which was focused on developing silicon to optimize general-purpose CPU computing and storage ↗. Two very different companies optimized their efforts for infrastructure for different eras of computing and software paradigms ↗.
