Since I personally don’t have any experience with high-performance 
contemporary CPUs and can’t remember all those reviews I read in my newsfeed 
from time to time, I tend to visit benchmark sites like the aforementioned 
cpubenchmark.net. Those provide comparable numbers of synthetic and/or 
real-world benchmarks for both single- and multi-core use cases.

The Phoronix Test Suite is another notable name, and also very 
linux-centric. I haven’t used that one myself yet, but have a look and click 
around:
https://openbenchmarking.org/suites/pts

It’s open source, so you can run it on your own machine to get comparison 
numbers.
