The company says C7g instances are suited to a wide range of compute-intensive workloads including web servers, load balancers, gaming, video encoding, scientific modelling, and machine learning inferencing.

Graviton2-based instances were launched in 2020, and are now used by 48 of the top 50 Amazon EC2 customers.

The new new C7g instances are said to deliver up to 2x faster performance for cryptographic workloads, up to 3x faster performance for machine learning inference, and nearly 2x higher floating point performance for scientific, machine learning, and media encoding workloads.

Other Graviton3 benefits include using up to 60% less energy for the same performance than comparable EC2 instances.

C7g instances also use the latest DDR5 memory for 50% higher memory bandwidth than Graviton2-based instances, which is important for memory-intensive scientific applications. They also provide 20% higher networking bandwidth than C6g instances.

“Customers of all sizes are seeing significant performance gains and cost savings using AWS Graviton-based instances,” said AWS vice president of Amazon EC2 David Brown.

“Since we own the end-to-end chip development process, we’re able to innovate and deliver new instances to customers faster. With up to 25% better performance than current generation Graviton instances, new C7g instances powered by AWS Graviton3 processors make it easy for organisations to get the most value from running their infrastructure on AWS.”
