Amazon Web Services announced that Amazon Neptune, its managed graph database service, now supports R7g and R8g instance types powered by AWS Graviton3 and Graviton4 processors in five more regions including Hong Kong, Osaka, Singapore, Canada (Central), and US West (Northern California). These instances feature the latest DDR5 memory technology, providing faster data access, and offer up to 30 Gbps of enhanced networking and significant EBS bandwidth.
R7g instances are priced approximately 16% lower than previous-generation R6g instances, while Graviton4-based R8g instances deliver up to 40% better performance compared to Graviton3. The R8g family supports larger sizes (up to 48xlarge) and an 8:1 memory-to-vCPU ratio, catering to more demanding workloads. Users can upgrade existing Neptune clusters by modifying the instance type for engine versions 1.4.5 or higher.
