Looks like that video is running Windows 10 as well. Pretty sure that is what the "activate Windows" ghost is from.
So the video is running a different OS, a newer faster cpu, different memory (ddr4 vs ddr3), a different mobo, probably an ssd, etc and you're wondering why he is getting frame drops in slightly different places than you are?
IT'S BECAUSE HE IS USING A DIFFERENT COMPUTER! Even if everything was exactly the same there would still probably be differences. Even repeating the same loop on the same computer would probably have slight variations each time.
