R8g instances expand to Asia Pacific, Europe, GovCloud, South America, and Mexico regions, while M8g instances gain support in US West, Asia Pacific, Canada, Europe, South America, and Africa regions. Graviton4-based instances offer up to 40% performance improvement and up to 29% better price/performance over Graviton3 equivalents. R8g instances support 24xlarge and 48xlarge sizes with up to 192 vCPUs, DDR5 memory, 50Gbps networking, and 40Gbps EBS bandwidth. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Which AWS regions now support Graviton4-based R8g instances for Amazon RDS and Aurora? R8g instances are generally available for Amazon Aurora (MySQL and PostgreSQL compatible) and Amazon RDS for PostgreSQL, MySQL, and MariaDB in Asia Pacific (Hyderabad, Melbourne, Malaysia), Europe (London, Paris, Zurich), AWS GovCloud (US-East), South America (Sao Paulo), and Mexico (Central). M8g instances are separately available in other regions. _Teams planning Graviton4 migrations can track regional rollout details like these on daily.dev._ ### What performance gains do AWS Graviton4 R8g and M8g database instances offer over Graviton3? Graviton4-based instances deliver up to 40% performance improvement and up to 29% better price/performance for on-demand pricing compared to equivalent Graviton3 instance sizes on Amazon Aurora and RDS, with results varying by database engine, version, and workload. R8g instances also add new 24xlarge and 48xlarge sizes with up to 192 vCPUs and DDR5 memory. _Engineers weighing a Graviton4 upgrade for database workloads follow announcements like this on daily.dev._ ### What are the maximum specs of the new R8g 48xlarge database instance size on AWS? The R8g 48xlarge size, built on the AWS Nitro System, delivers up to 192 vCPUs with an 8:1 ratio of memory to vCPU using DDR5 memory, up to 50Gbps of enhanced networking bandwidth, and up to 40Gbps of bandwidth to Amazon Elastic Block Store (EBS). _Database architects sizing large-instance workloads keep up with specs like these on daily.dev._ ## Similar posts on daily.dev - [Amazon Aurora PostgreSQL now supports R8g database instances in additional AWS regions](https://daily.dev/posts/amazon-aurora-postgresql-now-supports-r8g-database-instances-in-additional-aws-regions-4belkfurr) · AWS · 0 upvotes · 0 comments - [Amazon EC2 R8g instances now available in additional regions](https://daily.dev/posts/amazon-ec2-r8g-instances-now-available-in-additional-regions-qync2gwfs) · AWS · 0 upvotes · 0 comments - [Amazon RDS and Aurora expand R8gd and M8gd to additional Regions](https://daily.dev/posts/amazon-rds-and-aurora-expand-r8gd-and-m8gd-to-additional-regions-wgzz3wz0d) · AWS · 1 upvotes · 0 comments - [Amazon Neptune Database now supports R7g and R8g instances in 5 additional regions](https://daily.dev/posts/amazon-neptune-database-now-supports-r7g-and-r8g-instances-in-5-additional-regions-ojh25jlip) · AWS · 0 upvotes · 0 comments --- Tags: [#aws](https://daily.dev/tags/aws), [#backend](https://daily.dev/tags/backend) [View this post on daily.dev](https://daily.dev/posts/amazon-rds-and-aurora-now-support-r8g-and-m8g-database-instances-in-additional-aws-regions-wj7kqesch) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Amazon RDS and Aurora now support R8g and M8g database instances in additional AWS Regions","url":"https://daily.dev/posts/amazon-rds-and-aurora-now-support-r8g-and-m8g-database-instances-in-additional-aws-regions-wj7kqesch","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/amazon-rds-and-aurora-now-support-r8g-and-m8g-database-instances-in-additional-aws-regions-wj7kqesch"},"datePublished":"2026-07-15T18:05:44.891Z","dateModified":"2026-09-14T06:12:28.598Z","description":"AWS Graviton4-based R8g and M8g database instances are now available for Amazon RDS and Aurora in additional AWS regions worldwide.
