m6i Instances with 3rd Gen Intel Xeon Scalable Processors Delivered Better Estimated SPECrate®2017_int_base Scores Than m5 Instances with 2nd Gen Intel Xeon Scalable Processors
Whether a solution is on-premises or cloud-based, high integer performance is necessary for many applications to function smoothly. The SPECrate®2017 Integer benchmark measures integer performance, with higher scores representing higher throughput. The results of benchmarks like SPECrate®2017 Integer and similar can help guide the decisions of cloud customers faced with hundreds of instance options.
In Intel testing on Amazon Web Services (AWS) at multiple instance sizes, Amazon EC2 m6i instances enabled by 3rd Gen Intel Xeon Scalable processors delivered higher estimated SPECrate®2017_ int_base performance than m5 instances with 2nd Gen Intel Xeon Scalable processors. Read on to see the performance differences that testing revealed.
Better Integer Performance for Small Instances
Figure 1 highlights the results of a small-instance comparison pitting a 4-vCPU m6i instance against a 4-vCPU m5 instance. The m6i instance featuring 3rd Gen Intel Xeon Scalable processors was the clear leader, delivering 27% more estimated integer performance than the m5 instance.
Better Integer Performance for Medium Instances
Figure 2 highlights the performance difference between a 16-vCPU m6i instance with new 3rd Gen Intel® Xeon® Scalable processors and an m5 instance with 2nd Gen Intel Xeon Scalable processors. Here again, the m6i instance came out on top, delivering 23% more estimated integer performance than the m5 instance.
Better Integer Performance for Larger Instances
As Figure 3 shows, at the 16-vCPU instance size, an m6i instance featuring 3rd Gen Intel Xeon Scalable processors outperformed a 16-vCPU m5 instance by approximately the same margin as it did at the 8-vCPU instance size.
At each of the three sizes Intel tested, Amazon EC2 m6i instances enabled by 3rd Gen Intel Xeon Scalable processors delivered higher estimated SPECrate®2017_int_base performance than m5 instances with older processors. This clear performance boost can help guide organizations seeking to optimize their cloud investment.
