Now available: C4 instances, featuring the highest compute performance on Amazon EC2

You can now launch C4 instances, the latest generation of Amazon EC2 Compute-optimized instances. C4 instances are designed for compute-bound workloads, such as high-traffic front-end fleets, MMO gaming, media processing, transcoding, and High Performance Computing (HPC) applications.

C4 instances are available in five sizes, offering up to 36 vCPUs. C4 instances are based on Intel Xeon E5-2666 v3 (codename Haswell) processors that run at a base frequency of 2.9 GHz, and can deliver clock speeds as high as 3.5 GHz with Intel ® Turbo Boost. Each C4 instance type is EBS-optimized by default and at no additional cost. This feature provides 500 Mbps to 4,000 Mbps of dedicated throughput to EBS above and beyond the general purpose network throughput provided to the instance. C4 instances also provide Enhanced Networking for higher packet per second (PPS) performance, lower network jitter, and lower network latencies. The specifications of C4 instances are provided in the table below.

* Pricing for US East (N. Virginia) and US West (Oregon) AWS regions. For pricing in other regions, please visit the Amazon EC2 pricing page.

C4 instances are currently available in the US East (N. Virginia), US West (Oregon), US West (N. California), EU (Ireland), Asia Pacific (Singapore), Asia Pacific (Sydney), and Asia Pacific (Tokyo) AWS regions, with the support in other regions coming soon.
