Starting today, Amazon EC2 C5 instances will be available in new 12xlarge and 24xlarge sizes. These new instances will be powered by custom 2nd Generation Intel Xeon Scalable Processors (based on the Cascade Lake architecture) with sustained all-core turbo frequency of 3.6 GHz and maximum single core turbo frequency of 3.9 GHz. New Cascade Lake processors enable a new feature called Intel DL Boost which will help speed up typical machine learning operations like convolution, and automatically improve inference performance over a wide range of deep learning workloads. 

C5 instances are optimized for compute-intensive workloads and deliver cost-effective high performance at a low price per compute ratio. These instances are ideal for high-performance computing (HPC), machine learning, deep inference, distributed analytics, batch processing, and much more. With the new 24xlarge size, C5 instances increases available resources by 33% to provide even more resources and performance for those compute intensive workloads. 

With these new sizes, C5 instances are now available in 8 sizes, with 2, 4, 8, 16, 36, 48, 72, and 96 vCPUs and can be purchased as On-Demand, Reserved or Spot Instances. These instances are available in all the AWS Regions where the existing sizes are already available, including AWS China (Beijing) region, operated by Sinnet and AWS China (Ningxia) region, operated by NWCD.
