Don't refer to userbenchmark. Their ratings are so blatantly manipulated that they've gotten themselves banned from virtually every forum or subreddit for hardware advice. You know something's up when both r/Intel and r/AMD ban a "benchmarking" site.

What's an alternative for when I want ballpark performance numbers, where I'm not making a purchasing decision and I just want to know, "compared to what I have, is this other thing a {little,lot}{slower,faster} or about the same? Where "about the same" is within ~20% and the little/lot line is around 100% (double)?

Here is an alternative. None of them are perfect but for spur of the moment comparisons, a consistent "general" CPU benchmark should probably work well enough.

If it matters, i.e. purchase/usage decision, you really should dig into specific benchmarks that reflect your use (e.g. the actual application or game).

AnandTech Bench is a decent resource. https://www.anandtech.com/bench/

That looks great for a detailed comparison, but is quite a bit too much information for when I just want a quick "I haven't looked up that cpu before, what ballpark performance is it?
