C5 Instances are finally available!


Posted on November 8th 2017

New compute-intensive C5 instances are available today in six sizes for launch in three AWS regions! These instances are designed for compute-heavy applications like batch processing, distributed analytics, high-performance computing (HPC), ad serving, highly scalable multiplayer gaming, and video encoding. The new instances offer a 25% price/performance improvement over the C4 instances, with over 50% for some workloads. They also have additional memory per vCPU, and (for code that can make use of the new AVX-512 instructions), twice the performance for vector and floating point workloads.

Each vCPU is a hardware hyperthread on a 3.0 GHz Intel Xeon Platinum 8000-series processor. This custom processor, optimized for EC2, allows you have full control over the C-states on the two largest sizes, allowing you to run a single core at up to 3.5 GHz using Intel Turbo Boost Technology.

You can launch C5 instances today in the US East (Northern Virginia), US West (Oregon), and EU (Ireland) Regions in On-Demand and Spot form (Reserved Instances are also available), with additional Regions in the works.
