As always, thank you for your excellent suggestion.
My plan is to basically duplicate what they do over at PassMark's site cpubenchmark.net
https://www.cpubenchmark.net/compare/5027vs5684vs5172vs2830/AMD-Ryzen-9-7900X-vs-Intel-i9-14900KF-vs-AMD-Ryzen-5-7600-vs-Intel-Xeon-E5-2667-v4
Definitely won't be easy. But comparison like that is extremely helpful.
Side note: pretty sure I'm going with the Ryzen 7900X on the new database server. Currently running Dual E5-2667 v4. The 7900X hits where I need it most (single thread) and a single CPU will blow the doors off what I'm running right now. ... couple that with Ryzen's ECC memory support and then they say that the AM5 socket will be the platform until 2027 so upgrade options for many years. -- when you run a mysql database query, that's a single thread operation. Excited to get it built and compare performance.
So imagine that comparison but with internet benchmarks. Easy to understand and easy to use.
