Need more powerful compute services than the regular AWS EC2? The new C5 instances are designed to take on compute-intensive tasks: high-level analytics, machine learning inferencing, HPC, high-end video gaming, video encoding, batch processing, and so on.
The C5 series includes the next generation of hardware, including a hypervisor, which lets the host CPU allocate nearly all its resources to the instance type. This gives you the compute power you need without compromising security and providing consistent performance. As such, the C5 boasts of 25%-50% higher price/performance ratio compared to its predecessor, the C4 series. It also offers significantly more network and EBS bandwidth.
Sizes for C5 Instances
The new series includes a customized 3.0 GHz Intel Xeon Platinum 8000-series processor, with every vCPU a hardware hyperthread. The two largest sizes can give you complete control over the C-states for compute power of up to 3.5 GHz using Intel Turbo Boost Technology.

| c5.18xlarge | 72 | 144 GiB | 9 Gbps | 25 Gbps |
C5 instances require Elastic Network Adapter (ENA) and NVMe drivers for its HVM AMIs. However, latest versions of Amazon Linux, Microsoft Windows Server 2012 R2 and Windows Server 2016, Ubuntu, RHEL, CentOS, SLES, Debian and FreeBSD AMIs support the C5 series.
You may launch an On-Demand or Spot instance of the C5 series today in any of three regions: US East (Northern Virginia), US West (Oregon), and EU(Ireland). More regions to come soon.
