You can now launch R5 instance types when using Amazon RDS for Oracle in the AWS China (Ningxia) Region, operated by NWCD, and AWS China (Beijing) Region, operated by Sinnet. AmazonEC2 R5 instances are the next generation of Amazon EC2 Memory Optimized Instances

R5 instances have a 1:8 vCPU to memory ratio, with the largest size offering up to 768 GiB of memory per instance, well suited for memory intensive database workloads such as data warehousing and analytics. 

You can easily scale up to these new instance classes by modifying your existing DB instance in the AWS Management Console. Please refer to the Amazon RDS User Guide for more details. Refer to Amazon RDS Pricing for pricing and regional availability.
