Specifically, I don’t like them because they show really vague percentages or “scores” where it’s very unclear what specific benchmarks are being used. The benchmark bars for things like single and multi-core performance don’t break down different applications and use cases or even say which benchmarks they are referring to.

This link in particular never goes deeper than Geekbench and has a bunch of comparisons to stuff that shouldn’t guide purchase decisions like:

Newer - released 1 year and 4 months later

More modern manufacturing process – 3 versus 6 nanometers

I much prefer the more in-depth tests that outlets like GamersNexus do, where CPUs are tested using multiple workflows and solutions. For example, you can test specific games and applications, test file compression and video encoding, test simulation speed on CPU-dependent simulation games, test clock speed behavior and throttling (does the CPU have jittery boost clocks or does it settle in to a consistent frequency).
