AI打分理由: "正文主线是AWS官方宣布既有C8gn通用网络优化型EC2实例扩展至巴黎区域，CPU AI推理仅为应用场景之一，并非超节点或机架级AI基础设施。文章给出Graviton4、六代Nitro卡、600Gbps网络、120Gbps EBS、384GiB内存及EFA支持规格，且区域可用构成明确商业动作。固定知识库未见C8gn同事件，但本文新增仅为巴黎区域开放，未发布新产品、机架拓扑、关键部件路线或规模AI部署；命中主题弱相关否决，当前页面虽为完整官方原文，仍不具备高价值准入条件。"

Starting today, Amazon Elastic Compute Cloud (Amazon EC2) C8gn instances, powered by the latest-generation AWS Graviton4 processors, are available in the AWS Europe (Paris) region. The C8gn instances provide up to 30% better compute performance than Graviton3-based Amazon EC2 C7gn instances. Amazon EC2 C8gn instances feature the latest 6th generation AWS Nitro Cards, and offer up to 600 Gbps network bandwidth, the highest network bandwidth among network optimized EC2 instances.

Take advantage of the enhanced networking capabilities of C8gn to scale performance and throughput, while optimizing the cost of running network-intensive workloads such as network virtual appliances, data analytics, CPU-based artificial intelligence and machine learning (AI/ML) inference.

For increased scalability, C8gn instances offer instance sizes up to 48xlarge, up to 384 GiB of memory, and up to 120 Gbps of bandwidth to Amazon Elastic Block Store (EBS). C8gn instances support Elastic Fabric Adapter (EFA) networking on the 16xlarge, 24xlarge, 48xlarge, metal-24xl, and metal-48xl sizes, which enables lower latency and improved cluster performance for workloads deployed on tightly coupled clusters.

C8gn instances are available in the following AWS Regions: US East (N. Virginia, Ohio), US West (Oregon, N.California), Europe (Frankfurt, Stockholm, Ireland, London, Spain, Zurich, Milan, Paris), Asia Pacific (Singapore, Malaysia, Sydney, Thailand, Mumbai, Seoul, Melbourne, Jakarta, Hyderabad, Tokyo, Hong Kong), Middle East (UAE), Africa (Cape Town), Canada West (Calgary, Central), South America (Sao Paulo), AWS GovCloud (US-East, US-West).
