In this AWS Tutorials, we will see Amazon EC2 M5 vs C5 Instance Comparison.
AWS M5 EC2 instance – Cost | Performance | Benefits | Features
Amazon EC2 M5 family is the new generation instance in general-purpose computing that offers balanced Memory, CPU, and Network for high workloads.
These Instances are good for web and application servers, enterprise applications as backend servers, gaming clusters, and app development. 
Benefits of M5 instance:
- Flexibility to choose between 18 different instances with multiple processor options (Intel / AMD) and storage options (EBS / NVMe SSD).
- M5 instance has a higher density than the previous generation which results to reduce cost.
- Maximize resource efficiency as they are built on Nitro System which results in better overall performance.
Features of M5 instance:
- M5 instance features the Intel Xeon 8000 series processor which is also called Skylake-SP Processor with sustained all core Turbo CPU clock speed up to 3.1GHz.
- 20% performance improved in Compute and Price compare to M4 instance.
- M5 comes with ENA (Elastic Network Adapter) and NVMe (NVM Express) which results in high throughput and low latency interface for network bandwidth and EBS
- AWS provides a larger M5 instance size called m5.24xlarge which comes with 96 vCPU, 384 GiB RAM (memory) and 25 Gbps Network bandwidth these results or helps for running high workloads to run more cost-effectively.
| Model | vCPU | Memory (GiB) | Instance Storage (GiB) | Network Bandwidth (Gbps) | EBS Bandwidth (Mbps) |
| m5.large | 2 | 8 | EBS-Only | Up to 10 | Up to 3,500 |
| m5.xlarge | 4 | 16 | EBS-Only | Up to 10 | Up to 3,500 |
| m5.2xlarge | 8 | 32 | EBS-Only | Up to 10 | Up to 3,500 |
| m5.4xlarge | 16 | 64 | EBS-Only | Up to 10 | 3,500 |
| m5.12xlarge | 48 | 192 | EBS-Only | 10 | 7,000 |
| m5.24xlarge | 96 | 384 | EBS-Only | 25 | 14,000 |
AWS C5 EC2 instance – Cost | Performance | Benefits | Features
Amazon EC2 C5 instances are the new generation of compute-optimized instance family. It provides a low cost per vCPU and basically it is used for running high compute workloads.
Example: C5 instance can be used for high-performance computing applications, high-end web servers, batch processing, ad serving, video encoding, machine learning, and scientific modeling.
Features for C5 Instance Type:
- C5 instance has Turbo CPU clock speed up to 3.4GHz, Processor is Intel Xeon 8000 series.
- Single-core turbo up to 3.5Ghz with Intel turbo Boot Technology. C5 instance has 25% improvements in compute, memory and performance compare to C4 instances.
- C5 instance also comes with high-performance local storage NVMe-based SSD storage which is physically connected to the host server.
- C5 instance supports up to 25 Gbps network bandwidth which is suited for compute workloads that are not network bound.
- C5 is built on AWS Nitro System. Nitro System offloads many of the traditional virtualization functions to dedicated hardware and software to deliver high performance, HA, Security and also reducing virtualization overhead.
| Model | vCPU | Memory (GiB) | Instance Storage (GiB) | Network Bandwidth (Gbps) | EBS Bandwidth (Mbps) |
| c5.large | 2 | 4 | EBS-Only | Up to 10 | Up to 3,500 |
| c5.xlarge | 4 | 8 | EBS-Only | Up to 10 | Up to 3,500 |
| c5.2xlarge | 8 | 16 | EBS-Only | Up to 10 | Up to 3,500 |
| c5.4xlarge | 16 | 32 | EBS-Only | Up to 10 | 3,500 |
| c5.9xlarge | 36 | 72 | EBS-Only | 10 | 7,000 |
| c5.18xlarge | 72 | 144 | EBS-Only | 25 | 14,000 |
