SageMaker Notebook 实例现在支持 P5en.48xl 实例类型
Amazon Web Services · 2026-05-28 · via Recent Announcements

我们很高兴地宣布,Amazon EC2 P5en.48xl 实例在 SageMaker Notebook 实例上全面推出。

Amazon EC2 P5en 实例采用 8 个 H200 GPU,与 P5 实例采用的 H100 GPU 相比,其 GPU 内存大小和 GPU 内存带宽分别为 1.7 倍和 1.4 倍。P5en 实例将 H200 GPU 与高性能的第四代定制英特尔至强可扩展处理器搭配,支持 CPU 和 GPU 之间的 Gen5 PCIe,提供高达 4 倍的带宽,可以提高人工智能的训练和推理性能。与使用上一代 EFA 和 Nitro 的 P5 相比,P5en 采用 Nitro v5 和高达 3200 Gbps 的第三代 EFA,将延迟降低了 35%。这有助于提高分布式训练工作负载的集体通信性能,如深度学习、生成式人工智能、实时数据处理和高性能计算(HPC)应用程序。

Amazon EC2 P5en.48xl 实例已在 AWS 美国东部(弗吉尼亚州北部和俄亥俄州)、美国西部(俄勒冈州)和亚太地区(东京)区域的 SageMaker Notebook 实例上推出。
