  https://aws.amazon.com/blogs/big-data/amazon-redshift-rg-faster-and-lower-cost-graviton-powered/ RG is both faster and cheaper. While cloud vendors typically charge more for faster performance or newer generation hardware, Amazon Redshift delivers better performance at lower cost. With RA3, data lake queries offloaded scans to a separate compute fleet known as Amazon Redshift Spectrum. Because data lake queries ran on this separate compute, additional overhead was introduced to transfer query metadata and results between RA3 clusters and the Spectrum fleet. Amazon Redshift RG instances include a completely new built-in scan layer designed from the ground up for data lakes. This new scan layer includes a purpose-built I/O subsystem that incorporates smart prefetch capabilities to reduce data latency.
