Google's Trillium TPU: Powering the Future of AI
Google launches Trillium TPU, its 6th generation AI accelerator, offering 4.7x performance increase and 3x larger inference throughput. This breakthrough boosts AI training for models like Llama 2 and GPT3, fueling Google's Gemini 2.0 AI agent initiative.
Unveiling Trillium: Google's Sixth-Generation TPU and AI Hypercomputer Infrastructure
As a programmer, you are undoubtedly aware of the need for a robust foundation to effectively scale and enhance AI training, fine-tuning, and inference workloads while maximizing system performance and cost efficiency. Google's custom-built accelerator, the Tensor Processing Unit (TPU), has been specifically designed for AI and is now in its sixth generation: the Trillium TPU.
The Trillium TPU not only supports Google's search, photo, and map services but has also contributed to breakthroughs in scientific domains, most notably the Nobel Prize-winning AlphaFold 2 model, which accurately predicts protein structures.
The latest Trillium TPU boasts a 4.7x peak performance increase per chip over its predecessor, a maximum increase of 3x for inference processing, and a 67% improvement in energy efficiency. Moreover, it offers a 4x improvement in training speed for large language models like Llama 2 70B and GPT3 175B.
With Google's entry into the Gemini 2.0 era and the pursuit of AI agents capable of independently completing complex tasks, the Trillium TPU plays a crucial role in training a series of Gemini 2.0 models. Its near-linear scaling capabilities allow for efficient and accurate workload distribution, significantly improving training speed.

The Trillium TPU is currently the most cost-effective TPU available, offering strong performance and energy-saving capabilities for reduced costs. It has been made available to all cloud customers since December 2024.
Given that there is no one-size-fits-all solution for AI workloads, Google has adopted various hardware strategies and partners, including NVIDIA, AMD, Intel, Arm, and others. These partnerships provide cloud customers with a variety of options, addressing factors beyond computational power, such as cost and resource allocation.
