AWS expanded availability of R8g and M8g instance types based on Graviton4 processors to numerous regions worldwide, including Asia Pacific, Europe, and South America. These instances provide up to 40% better performance and 29% improved price/performance over previous Graviton3-based instances, featuring enhanced CPU, memory, networking, and DDR5 memory support.
The new R8g sizes offer up to 192 virtual CPUs and increased networking bandwidth, improving database workloads on Amazon Aurora (MySQL and PostgreSQL compatible) and Amazon RDS for multiple engines. AWS provides easy launch options but independent validation of these performance claims is not stated in the source.
