Which is why you got a honest thumbs up.
Mentioning its a review sample, being clear about what you do and why you do it.
Like that everyone can decide if it's worth looking into it and spending time, or not.

So when I say "their reviews are fine for basic stuff" I don't mean that what they do is basic (you get spammed with tables that any1 not having studied statistics must get annoyed by from time to time) but that anytime they go deep they do mistakes, just like we all do.
So now ... because of this review ppl will think wow +10% performance, lets go and buy 4x8GB kits. Which is exactly the wrong conclusion.

I still have a 4650G over here. Just an average chip though.

Turns out that my "2nd best" SR B-die is able to offer higher RAM clock 

Or have a look how RocketLake with their new UHD 750 IGPU (i5-11500 and above) is doing.
Matter of fact I received a i5-11500 today and will start testing it late this or next week when I have the time doing so. 

UHD Graphics 750 is Iris Xe

APU: AMD R7 5700G
RAM: 2x8GB 3733 22-23-23-55 HP37D4U1S8ME (HyperX Fury) (XMP 1)

1) so far using HWiNFO64, from my past experience (Renoir APU) with the digital reading from my AX1200i and a watt meter it's accurate. After I'm done with all my stuff I will slap a Fuma 2 on and show wall power draw.
2) For sure! That's just the XMP. SPD not accessible and RAM not mine so I can't take off heatspreaders to see what memory IC it is using. Anyways once Curve OC is done RAM is next on the list. Will figure with timings/frequency which memory IC I am likely to be dealing with.
