AMD EPYC vs. Intel Xeon Cascadelake With Facebook's RocksDB Database
Written by Michael Larabel in Processors on 17 October 2019. Page 3 of 3. 9 Comments

Not only does EPYC Rome do very well with RocksDB in raw performance, but it easily dominates when it comes to performance-per-dollar. Pricing on the processors via their current list/retail pricing.

AMD EPYC 7002 series offers terrific value for any RocksDB servers, similar to the strong performance seen out of the PostgreSQL 12.0 database performance. At least with Intel's current public Cascade Lake pricing, Rome is the hands-down winner.

For those wondering about the EPYC 7002 series power efficiency at 7nm, those extensive Linux tests are currently being worked on.

Beyond the performance and value proposition, not covered by these metrics but also quite compelling on the AMD EPYC 7002 front is the greater number of PCIe lanes (48 for Intel vs. 64 for AMD per socket) in allowing more PCIe SSDs per database server. As well, the PCI Express 4.0 support with AMD EPYC Rome opens the door for even greater database server performance albeit we have yet to test any PCIe 4.0 enterprise SSDs to measure that uplift.
