I compiled a binary with gcc 6 and clang 3.9.1. This are the result from 3 runs for every binary. Used only world no nether and no the end.

In world/world.ini changed:
PregenerateDistance to 100
Seed to 42

clang 3.9.1

As you can see gcc beats clang. I didn't changed anything in the source and added no flags.

The question is now why. I know that there are a few warnings in the noise generator with shift left negative value and overflow. Maybe clang adds additionally checks or doing some casting with the numbers.

To be safe I copied the world.ini from here

Nice, good to see that there haven't been any regressions from 2018! Congrats on actually finding stock for the processor...

The 5600X and 5800X can easily be found at MSRP here in The Netherlands. The 5900X and 5950X on the other hand...
