Amazon EC2 C7g Instances

Best price performance for compute-intensive workloads in Amazon EC2

Amazon Elastic Compute Cloud (Amazon EC2) C7g instances, powered by the latest generation AWS Graviton3 processors, provide the best price performance in Amazon EC2 for compute-intensive workloads. C7g instances are ideal for high performance computing (HPC), batch processing, electronic design automation (EDA), gaming, video encoding, scientific modeling, distributed analytics, CPU-based machine learning (ML) inference, and ad serving. They offer up to 25% better performance over the sixth-generation AWS Graviton2-based C6g instances. C7g instances are the first in the cloud to feature Double Data Rate 5 (DDR5) memory, which provides 50% higher memory bandwidth compared to DDR4 memory to enable high-speed access to data in memory.

C7gn instances are powered by AWS Graviton3E processors and the latest generation Nitro Cards. C7gn instances offer up to 200 Gbps of network bandwidth and up to 50% higher packet-processing performance than existing Graviton-based EC2 instances. These new instances are ideal for running the most demanding network-intensive workloads, such as network virtual appliances, data analytics, and CPU-based artificial intelligence and machine learning (AI/ML) inference.

Beamr is a leading provider of image and video optimization solutions that enable professional photographers to improve their workflows, photo sharing services to improve UX and reduce churn, and video service providers to reduce storage and delivery costs.

"Beamr's JPEGmini software, written in C/C++, optimizes JPEG image files by reducing their file size without compromising quality. The application is a compute-intensive and includes functions for image decoding, image encoding, and a quality measure algorithm that analyzes various image attributes. Since the mobile version of this software runs on Arm processors, we decided to test its performance on AWS Graviton3-based Amazon EC2 C7g instances. Rebuilding our software to run on C7g instances took us one working day, and the results were promising. When running on C7g instances, we saw 30% improved performance over comparable x86-based instances. Based on these results, we plan to recommend to our customers to run the Beamr JPEGmini software on Graviton3-based instances once those become GA, and we plan to benchmark Beamr’s H.264 and HEVC video encoders on Graviton instances as well."

ProSiebenSat.1 Media SE is a German digital and media company focused on entertainment, dating, commerce, and other ventures. Its wholly owned subsidiary, Seven.One Entertainment Group, offers viewers entertainment content across a variety of media technologies.

"The Seven.One Entertainment Group runs video transcoding, based on the open source tool ffmpeg, for on-demand content in Amazon EC2. In 2021, we switched to AWS Graviton2-based C6g instances and realized significant cost benefits over comparable x86-based instances. With C6g instances, we could also run more parallel transcoding tasks per EC2 instance, resulting in fewer instances and more cost savings. We have run transcoding tests with ffmpeg version 4.4.1 on the new AWS Graviton3-based C7g instances and benchmarked up to 40% faster performance compared to C6g instances. With a new build of ffmpeg version 5 using Arm64 optimizations, there are even greater performance gains, especially in near-live use cases. This enables to provide video on-demand content faster to our users."
