So, when I run cinebench benchmark couple of times in a row on my MacBook Pro 15 2018 i7, it will usually start around 1030, then second time around 960, and then 3rd or 4th time it will dip below 900, then it will come back to mid 900, then again 850ish etc. I was just wondering if that is normal thermal throttling or is my unit faulty?
