News AMD's 64-Core EPYC and Ryzen CPUs Stripped: A Detailed Inside Look

I don't understand why every site except Cowcotland says 3.9B transistors/CCD although the slide from the AMD presentation at Hot Chips 2019 mentionned in many of those articles says 3.8B transistors. It looks as if the original news from harwareluxx got it wrong and said 3.9B and everyone copied the error. Or it's the AMD slide that is wrong ?
