The title technically isn't...wrong, per se, but it's kinda obvious given how power limits work on any locked Intel chip or any PPT-limited AMD chip since 2019.

You can probably get the same result on Ryzen by artificially running 1066MHz Infinity Fabric @ 0.9V VSOC where you save like 10W on SVI2 SOC power draw compared to 1866MHz 1:1 IF @ 1.1V VSOC. Like, yeah, you get 10W more to invest into the cores (if not already current, temp or voltage limited) and will probably get slightly better boost performance out of strict CPU benchmarks, but people don't build new 11th gen computers to run CPU benchmarks 24/7 at stock settings and nothing else.

In return, running Gear 2 or low IF speed both get you doodoo performance in 99% of everything else outside of CPU benchmarks, so is it really "performance loss"? It's not even a revelation that's useful to overclockers because 1) 11400F isn't winning any races regardless of what you do 2) power limit is not an issue on anything that isn't locked 3) power limit isn't even an issue on the 11400F as long as you remove them.

So basically, "Gear 1 can lead to performance loss" is about the same as saying "1900MHz+ IF can lead to performance loss". Both technically true to some extent, and both misleading and benefiting precisely nobody.
While I agree with your summary of power budget limitations I don't agree with your conclusions, IF you can run those memory speeds and infinity fabric speeds(on Ryzen) it doesn't affect your core speed significantly.
I can't comment on Intel's thing I couldn't know having not dabbled or read enough yet but doesn't seem like too much of a drama and to me could be more nuanced, what if you have 3200/3600 memory, IE lower speeds than 4000/ , perhaps there's a gain to be had with less core performance loss, I dunno.
After all most go for the sweet spot memory frequency not the ceiling.

Intel is so against the wall that they can't run the memclock at full speed when using fast memory, due to the ancient manufacturing process they are forced to use, the cores need every Watt they can get their hands on just to offer almost AMD like performance!
Very interesting theory. So maybe that's why Gear 2 exists, so that low-watt SKUs can still use fast memory. Imagine a 35 W -T CPU running with the MC using up 15 W

Isn't Ryzen 3's MC located on the IO die which is made on GF 12nm? doesn't make sense that Ryzen MC is more efficient than Intel MC.
Also can you try messing with the Ring Cache ratio? they could improve/degrade efficiency to some degree.

I guess my car has Intel Inside as in Gear 2 its faster than in Gear 1.

Efficiency is barely a function of the process, what matters is the chip/circuit design and algorithms. Look at Navi 1x vs 2x

I suppose technically it's news, but gee so much time wasted reporting about an utterly crap product that should have never been released. Why delve into the minutia of an evolutionary dead end. Roll on Alder Lake and Zen3+/4.

Well just run it at the unlimited TDP mode or whatever raised TDP the motherboard allows. Running these at 65W is really dumb imo.
