When you run compute-intensive workloads like real-time analytics, batch processing, video encoding, scientific modeling, or CPU-based machine learning inference, every percentage point of performance matters. You need instances that deliver higher throughput per vCPU, faster memory access, and more network bandwidth, all while keeping your costs in check. Today I am happy to announce the general availability of Amazon Elastic Compute Cloud (Amazon EC2) C9g and C9gd instances, powered by AWS Graviton5 processors. C9g instances are compute-optimized and deliver up to 25% higher performance per vCPU compared to previous-generation C8g instances. They feature the fastest memory of any processor instance in the cloud, with DDR5 8800MT/s DIMMs, 5x more L3 cache, and up to 3x higher packet-processing performance compared to Graviton4-based instances. The faster memory and larger caches mean your workloads spend less time waiting on data, translating into higher throughput for in-memory analytics, faster agentic loops, and more responsive real-time applications. C9g instances are ideal for batch jobs, video encoding pipelines, or distributed analytics that can utilize Amazon Elastic Block Store (Amazon EBS) for storage. It is also a natural fit for agentic AI workloads, where concurrent environments and CPU-bound reasoning steps benefit from Graviton5’s higher core count and larger caches. As AI shifts from answering questions to taking actions, running code, and orchestrating multi-step tasks, the demand for CPU compute is growing, and C9g instances are built for this shift. Some workloads also need fast local storage alongside that compute power. Choose C9gd when your application benefits from…
