The Pixel Fold (2023) surpassed an Asus RS720A-E11 server with AMD EPYC processors in single-core benchmark tests. While the server has a significant advantage in multi-threaded performance due to its numerous cores, Google Research indicates that 25 to 50 smartphone motherboards could match the power of a single server.
Each smartphone motherboard contains 8 to 12 GB of RAM, sufficient for common academic applications. By clustering these boards using Kubernetes and switching to a Linux data center distribution, unnecessary background processes are eliminated, enhancing efficiency. Retaining existing smartphone hardware can reduce the need for new material extraction and manufacturing, addressing sustainability concerns.
