To quote from Anandtech:<p>Amazon is also making some very impressive benchmark comparisons against its fifth-generation instances, supporting Intel Xeon Platinum 8175 processor of up to 2.5GHz:<p><pre><code> All of these performance enhancements come together to give these new instances a significant performance benefit over the 5th generation (M5, C5, R5) of EC2 instances. Our initial benchmarks show the following per-vCPU performance improvements over the M5 instances:
- SPECjvm® 2008: +43% (estimated)
- SPEC CPU® 2017 integer: +44% (estimated)
- SPEC CPU 2017 floating point: +24% (estimated)
- HTTPS load balancing with Nginx: +24%
- Memcached: +43% performance, at lower latency
- X.264 video encoding: +26%
- EDA simulation with Cadence Xcellium: +54%</code></pre>
