AI打分理由: "正文为AWS官网C8g实例在新增区域可用的公告，属于通用CPU实例的区域扩展，主线是Graviton4计算实例可用性而非机架级AI基础设施、AI Rack或超节点关键部件。来源权威但历史知识库显示AWS已有P6-B200/B300等GPU超节点实例信息，本文仅新增台北、新西兰和GovCloud三个区域，无超节点架构、规格或部署新增。技术细节仅含vCPU、内存、网络带宽等普通实例参数，缺少rack-scale拓扑、互连或AI集群机制；商业信号仅为区域可用性扩展，无客户、订单、量产或部署计划。完整性较高但主题偏离超节点业务情报库，命中强否决项中应用与通用计算实例区域扩展，故非优质。"

Starting today, Amazon Elastic Compute Cloud (Amazon EC2) C8g instances are available in AWS Asia Pacific (Taipei, New Zealand), and AWS GovCloud (US-East) regions. These instances are powered by AWS Graviton4 processors and deliver up to 30% better performance compared to AWS Graviton3-based instances. Amazon EC2 C8g instances are built for compute-intensive workloads, such as high performance computing (HPC), batch processing, gaming, video encoding, scientific modeling, distributed analytics, CPU-based machine learning (ML) inference, and ad serving. These instances are built on the [AWS Nitro System](https://aws.amazon.com/ec2/nitro/), which offloads CPU virtualization, storage, and networking functions to dedicated hardware and software to enhance the performance and security of your workloads.  
  
AWS Graviton4-based Amazon EC2 instances deliver the best performance and energy efficiency for a broad range of workloads running on Amazon EC2. These instances offer larger instance sizes with up to 3x more vCPUs and memory compared to Graviton3-based Amazon C7g instances. AWS Graviton4 processors are up to 40% faster for databases, 30% faster for web applications, and 45% faster for large Java applications than AWS Graviton3 processors. C8g instances are available in 12 different instance sizes, including two bare metal sizes. They offer up to 50 Gbps enhanced networking bandwidth and up to 40 Gbps of bandwidth to the Amazon Elastic Block Store (Amazon EBS).  
  
To learn more, see [Amazon EC2 C8g Instances](https://aws.amazon.com/ec2/instance-types/c8g/). To explore how to migrate your workloads to Graviton-based instances, see [AWS Graviton Fast Start program](https://aws.amazon.com/ec2/graviton/fast-start/) and [Porting Advisor for Graviton](https://github.com/aws/porting-advisor-for-graviton).
