What is Generative AI and how does it work? AWS
DIRECTOR OF SUSTAINABILITY: CHRIS WALKER FOUNDED: 2002 EMPLOYEES: 143,000 HEADQUARTERS: WASHINGTON, US
AWS designs its own silicon for AI. The second-generation Trainium2 and Inferentia2 chips are positioned to deliver higher throughput for training and inference at better energy efficiency than previous versions.
“ Trainium2 is purpose built to support the largest, most cuttingedge generative AI workloads, for both training and inference, and to deliver the best price performance on AWS,” says David Brown, Vice President of Compute and Networking at AWS.
“ With models approaching trillions of parameters, we understand customers also need a novel approach to train and run these massive workloads.”
AWS also offers built-in optimisation for deployed models so customers can hit the same quality with fewer operations. Across both new and existing data centres, AWS is rolling out liquid cooling to remove heat more efficiently than air at high density, which reduces the extra power spent on fans and chillers and allows more AI compute in the same footprint.
“ AWS’ s holistic approach to efficiency helps to minimise both energy and water consumption in our data center operations, contributing to our ability to better serve our customers,” says Chris Walker, Director of Sustainability at AWS.
“ We are constantly working on ways to increase the energy efficiency of our facilities – optimising our data center design, investing in purpose-built chips and innovating with new cooling technologies.
“ As AWS takes steps toward reaching Amazon’ s net zero carbon by 2040, as part of The Climate Pledge, we will continuously innovate and implement ways to increase the energy efficiency across our facilities in an effort to build a brighter future for our planet.”
