Small-Scale Question Sunday for March 19, 2023

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

I don't know of a good way to work it a priori. I guess chip designers must have a way to be reasonably sure before they make the chips that they'll be faster than their predecessors.

But generally you'll want to use benchmarks, like https://www.cpubenchmark.net/. Benchmarking software runs a computationally expensive test, which is ideally somewhat representative of real-world workloads, to see how a given CPU performs. This is complicated by systems with the same CPU having different other components, but I assume they adjust for that somehow.
