Yes, that's why I qualified my "real-world tasks" with "random". What is clear is that:
* Ryzen has a longer branch prediction history than Intel's processors.
* This will give it an advantage on repetitive executions.
* It's a challenge to robustly measure tasks since using repeated executions to gain confidence intervals can interfere with the measurement itself.
What's not clear is to what extent real-world tasks are repetitive enough to benefit or random enough to be negatively impacted. It's likely a mix of both.
By no means am I attempting to spread FUD — I find it quite interesting and wanted to spark a bit of discussion on it.
Pardon. I didn't mean to imply you were intentionally doing that. Just trying to make sure there's skepticism of benchmarks as well as skepticism that the boost from branch prediction is dishonest.
