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?

It's normal that's how Mac's and some PC's are just designed. It's the trade off for a such a powerful CPU in a very thin & light chassis. As you repeat the test the CPU is forced to reduce frequency. For the score, you'd need to compare with others of the same model.

CPU Throttling down because of the heat. Sad but normal for i7 Notebooks from the Apple brand, I have the same issue with a 2011 Model.

Install the "Intel Power Gadget" tool, using this tool you are able to see the throttling, also the power consumption, temperature and clockrate of the CPU in real time.

Indeed sad but true, nor a small difference 850CB is pretty poor for an 8th Gen hex core i7, given a decent 7th Gen 7700HQ quad core i7 will push 750CB. The current 8th Gen hex core CPU's are tremendously performant when paired with a competent chassis with even the base 8750H i7 being capable of pushing 1300CB and maintaining 1200CB

whahah. i just did a test whit our new Computers. i5-8400 and i got 804 points. Nice.

On my MacPro 2010 i have around 1400 points, but that machine has two six-cores CPU's in it.

/edit: Retest and got 914 and 926 points

For a stress i use "yes > /dev/null &" for each thread on macs.

But that corona site says something about buying....? But the PC i am working on has a good CPU cooler :D

DL the Corona Benchmark it's free and will push the CPU hard on a rendering test. You'll see how good your cooler is then :p My numbers are from an ASUS ROG GL703GS notebook re-rolled as a portable workstation (8750H, 32GB @2666, GTX 1070, NVMe SSD & SSHD, soon to be replaced with a 2TB Samsung Evo)

Thermal limit of the notebooks chassis; Intel PL2 90W, PL1 65W, no thermal throttling

The notebook offers near desktop performance that you can throw in a bag and travel with. Currently up country now in Malaysia on my primary engineering project. The GL703GS came with 3 years OEM warranty as ASUS believes in their product, as opposed to Apple who only ever offers the minimum legal requirement on so called premium products :rolleyes:

TBH I've a better support policy with a $650 2in1 from Acer than I'd have with Apple's MBP and my spec would cost over $4,250...
