AI打分理由: "正文主线是AWS Graviton5通用内存型EC2实例新增四个区域可用，属于云厂商CPU实例的区域扩展，并非超节点、AI Rack或机架级AI基础设施主题；与超节点相关性弱。来源为AWS官方公告，权威性高。历史知识库未见M9g/M9gd此区域扩展信息，有一定区域扩展新增性，但核心M9g/M9gd及Graviton5此前已发布，本次仅新增区域，新颖性有限。正文缺少超节点相关架构、互连、HBM、CPO、NVLink、供电、液冷、RAS等技术细节，技术细节分低。无具名超节点客户、量产或部署信号。正文完整、来源可追溯，但只能算官方区域上线公告，未命中高价值准入通道，按主题弱相关和旧品区域扩展处理。"

Starting today, Amazon Elastic Compute Cloud (Amazon EC2) M9g and M9gd instances, powered by AWS Graviton5 processors, are available in Europe (Ireland) and Asia Pacific (Singapore, Sydney, Tokyo) regions. AWS Graviton5 processors are the fifth generation of custom-designed CPUs, delivering the best price performance for memory-intensive workloads running on Amazon EC2.

[M9g and M9gd instances](https://aws.amazon.com/ec2/instance-types/m9g/) deliver up to 25% better performance compared to AWS Graviton4-based M8g and M8gd instances. They are up to 30% faster for databases. These instances are built on the sixth-generation [AWS Nitro System](https://aws.amazon.com/ec2/nitro/) and are the first to feature the [Nitro Isolation Engine](https://aws.amazon.com/blogs/compute/aws-nitro-isolation-engine-formally-verifying-the-hypervisor-in-the-aws-nitro-system/), harnessing formal verification to provide mathematical assurance that customer workloads are isolated from each other and AWS operators, pioneering a new standard for mathematically proven cloud security.

M9g instances are ideal for workloads such as open-source databases, in-memory caches, big data analytics, and memory-intensive applications. M9gd instances offer local NVMe-based SSD block-level storage for customers running memory-intensive workloads that also require high-speed, low-latency local storage for scratch space, temporary files, and caches.

M9g and M9gd instances are available for purchase in these four regions via Savings Plans, On-Demand, Spot instances, Dedicated instances, or Dedicated hosts.
