Amazon EC2 C5 instances are the newest generation of Amazon EC2’s compute optimised instance family. The C5 family has definitely lived up to our expectations and proved itself superior in all aspect when compared to the equivalent instance types in the C4 family, especially when it comes to price and performance. Being C5 the new AWS efficiency leader in CPU throughput per dollar, it’s 4 to 15% more cost effective in terms of compute/memory per dollar. On C5 family the compute is cheaper, the memory is faster, and the network is also faster.
C5 instances are powered by 3.0 GHz Intel Xeon Scalable processors, and allow a single core to run up to 3.5 GHz using Intel Turbo Boost Technology. The Skylake processor has several improvements over the Haswell processor which is used in the C4 instance family.
Optimized to deliver the right combination of CPU, memory, storage, and networking capacity for a wide range of workloads, C5 features AWS hardware acceleration that provides consistent, high performance, low latency networking and storage resources. C5 instances are designed for running compute-heavy workloads like video encoding, batch processing, scientific modeling, high-performance computing (HPC), distributed analytics, highly scalable multiplayer gaming, machine/deep learning inference, high-performance web servers, and ad serving.
