Amazon Web Service (AWS) released its C4 instances on January 11th. Cloud Spectator was interested in its performance and price-performance improvements over its previous generation, the C3 instances, and therefore conducted a study comparing C4 instances’ performance and price-performance outputs against the C3 instances.
Some Key Findings
Some of the Key Findings in this report are:
- The C4 VMs had 10 to 20 percent higher vCPU performance than the C3 VMs across different machine sizes;
- The C4 VMs had approximately 6 GB/s more memory throughput than the C3 VMs across different machine sizes;
- The price-performance values of the C4 VMs were on average the same as those of the C3 VMs;
- Both vCPU performance levels and network throughput displayed high stability over time and across all tested machines;
