Amazon Web Services (AWS) CEO Matt Garman made groundbreaking announcements at the re:Invent conference on Tuesday, unveiling ambitious plans to compete directly with Nvidia in the AI chip market and build one of the world’s largest AI supercomputers.
AWS is developing UltraServers, powerful computing systems containing 64 of its proprietary Trainium 2 chips, designed to help companies scale their generative AI workloads. More impressively, the company is constructing an AI supercomputer called Project Rainier in partnership with AI startup Anthropic, in which Amazon has invested $8 billion. When completed in 2025, this UltraCluster will feature “hundreds of thousands” of Trainium chips and become “the world’s largest AI compute cluster reported to date,” according to Amazon’s blog post.
The announcements position AWS as a serious challenger to Nvidia’s dominance in the AI chip market. Garman emphasized that AWS’s goal is to reduce AI costs and provide customers with alternatives. “Today, there’s really only one choice on the GPU side, and it’s just Nvidia. We think that customers would appreciate having multiple choices,” Garman told the Wall Street Journal. However, he acknowledged that Trainium won’t dethrone Nvidia “for a long time,” but hopes it will “carve out a good niche” for many workloads.
Apple emerged as a surprise highlight of the keynote, with Benoit Dupin, Apple’s senior director of AI and machine learning, revealing that the tech giant uses AWS chips like Amazon Graviton and Inferentia for services including Siri. More significantly, Apple is in early testing stages of Trainium 2 chips to potentially train Apple Intelligence, its AI platform. Dupin praised AWS for keeping pace with Apple’s scale and innovation speed over their decade-long partnership.
AWS also introduced Amazon Nova, a new generation of foundational AI models that enable customers to understand videos, charts, and documents, or generate multimedia content. The Nova family includes Amazon Nova Micro, Lite, and Pro models, which Amazon claims are “at least 75% less expensive than the best-performing models in their respective intelligence classes.”
Additionally, AWS announced Trainium3, its next-generation chip, further demonstrating its commitment to competing in the AI hardware space alongside tech giants like Google and Microsoft, who are also developing alternatives to Nvidia’s expensive GPUs.

Today, there’s really only one choice on the GPU side, and it’s just Nvidia. We think that customers would appreciate having multiple choices
AWS CEO Matt Garman explained the company’s rationale for developing Trainium chips to the Wall Street Journal, highlighting the lack of competition in the AI chip market and AWS’s goal to provide alternatives to Nvidia’s dominant position.
But, hopefully, Trainium can carve out a good niche where I actually think it’s going to be a great option for many workloads — not all workloads
Garman tempered expectations about competing with Nvidia, acknowledging that while Trainium won’t dethrone the chip giant anytime soon, it can serve specific use cases effectively and provide customers with viable alternatives.
One of the unique elements of Apple business is the scale at which we operate and the speed with which we innovate. AWS has been able to keep the pace, and we’ve been customers for more than a decade
Benoit Dupin, Apple’s senior director of AI and machine learning, praised AWS’s ability to meet Apple’s demanding requirements during his appearance at the conference, validating AWS’s capabilities in supporting large-scale AI operations.
Our Take
AWS’s aggressive push into AI chips and supercomputing infrastructure reveals a critical strategic shift in the cloud computing landscape. By vertically integrating hardware and software, AWS is following the playbook of successful AI companies while leveraging its massive cloud customer base for distribution. The Apple partnership is particularly telling—if AWS can convince the world’s most vertically integrated tech company to consider its chips, it signals genuine technical competitiveness. However, the real test will be whether Trainium can match Nvidia’s software ecosystem and developer tools, which have created powerful lock-in effects. Project Rainier’s partnership with Anthropic also demonstrates how cloud providers are becoming kingmakers in the AI model development race, using infrastructure access as leverage to secure strategic relationships. The 75% cost reduction claim for Nova models suggests AWS is willing to operate on thin margins to capture market share, potentially forcing competitors like Microsoft Azure and Google Cloud to respond with their own price cuts.
Why This Matters
This announcement represents a pivotal moment in the AI infrastructure race, as AWS directly challenges Nvidia’s near-monopoly on AI chips. With AI demand exploding across industries, the availability of cost-effective alternatives could democratize access to AI training and deployment, potentially accelerating innovation across sectors.
Project Rainier’s scale is particularly significant, as it will rival Elon Musk’s xAI Colossus supercomputer and provide Anthropic with unprecedented computing power to develop next-generation AI models. This infrastructure investment underscores the massive capital requirements for frontier AI development and the strategic importance of controlling the hardware stack.
Apple’s consideration of Trainium 2 chips validates AWS’s approach and signals that even the most demanding tech companies are seeking alternatives to Nvidia. This could trigger a broader industry shift toward diversified chip suppliers, potentially reducing costs and supply chain risks. The introduction of Amazon Nova models at 75% lower costs than competitors also suggests a price war in AI services is intensifying, which could benefit businesses looking to implement AI solutions. These developments will shape the competitive landscape of AI infrastructure for years to come.
