My suspicion was in itself the same as Nick's.
There are probably shifts, because the unused variables are not removed.

Re: Strange speed up with unused variables
Btw: Why do I have such low values? Is the code that much faster on Linux or what could be the reason? I don't think that my CPU is much faster than any of yours.
The english grammar is freeware, you can use it freely - But it's not Open Source, i.e. you can not change it or publish it in altered way.
Re: Strange speed up with unused variables
Hi, yes, I had also expected more from it.
I don't have native Linux here unfortunately, only a VM on an old i7, for the other OS except Windows.
I have turned off the Core Boost.
With Core Boost, you also need water cooling with this thing or the fan will annoy you endlessly with eternal up and down.
But even the water cooling has fans, which are far less annoying but still a clear up and down.
Practically in normal operation, the boost doesn't bring anything either.
With my medium graphics card, the thing runs extremely fast in games, which is probably the primary use case for this CPU.
Unfortunately, I do not game is only because of the GPU support.
With boost ~ 715 / 870
It has become quieter and quieter with the newer bios versions.
With the first Bios versions I thought there is something broken, so crazy was that.

Re: Strange speed up with unused variables
Thanks for testing. It looks like i am the only one with a huge difference for that code snippet.

I was talking about this code snippet from other thread:
