Database Tests
Sometimes it is not the number of cores that matter but the access to oodles of low-latency memory bandwidth, as is the case with the in-memory NoSQL database test that is Redis.
Previously, the dual Epyc 7742 chips from the last generation were beaten by the Intel Xeon Platinum 8280 in three of the four tests, highlighting the potential stumbling blocks of running this application using Rome's caching hierarchy and organisation.
Third-gen Epyc does a whole lot better, underscoring the benefits of having up to 32MB of lower-latency L3 cache per eight-core complex. Server processors need to be well-balanced in every area, and Epyc 7003 Series is better than Epyc 7002 Series in ways that are not obvious from the specification sheet.
