Aehhhm, sorry, I dont see this.
First, the flights are not exactly the same. 11900k is roundabout 100 meters in front right from the start. So geometry load differs. If you look at the same point (e.g 0,29nm to airport sign at 0.33m) both are at 54fps.
Second, there are some points when the 11900k is in front (e.g. 1.26m, 60 vs 58 or 0.11m, 52 vs 33)
Third, frametimes are more constant on 11900k. Unfortunately 1%low and 0,1%low are not shown.
And: 10900k runs @ 4,90Ghz all core, not default!!! 11900k is not shown. Häääää???
For what reason ever, HT is on (pointing to other applications that benefit from HT is pointless, we are talking about msfs, nothing else). TPV, why? Played SOTTR and AC for to long? Pilots use to sit IN the cockpit.
What applications running in the background?
My conclusions:
This video is not very meaningful. Gently said.
11900k@?.??Ghz on eight cores is (almost) as fast as 10900k@4,90Ghz-allcore on ten. Newer cores are faster - probably good for msfs.
Nobody is forced to buy an 11900k. 10900k is fine too.
Beside this: 1,5GB more ram is used for the 10900k system!?
I agree 100% here beside even +30% ipc on an amd is not enough to heal the trauma.
