Yes it is generally very annoying that many reviewers skip out the ‘practical benefits’ part of the review.

So not too much difference then? Bit disappointing really, but I guess you're limited as to the impact a CPU can make at 4K.For my fellow 4k native gamers;
From what I've seen in reviews, for the most part it looks like an X870 board isn't necessary, unless you want the absolute best/bleeding edge.

Hence why reviewers never test a CPU using 4K gaming. It doesn’t tell you much.
On the contrary, it tells you what you need to know if you game at 4K.
Both sets of data are valuable.

It can tell you it's not overly worth getting. Guess it depends what narrative the reviewer is trying to spin. Why not go down to 720p or 480p, surely that'd make it look even better?

Sure thing. Just to make the CPU look ever better. Makes sense /s

isn't that what they're doing by testing at 1080p?
Yeah, as much as I love shiny new things, there's really no compelling reason to get one over my 7800X3D.
Maybe I'll save the cash for a £3K 5090 Strix

It also depends on what you'd be 'coming from' (assuming gaming is important) e.g. if someone is running an AMD 3600x or older, at ANY resolution (with an decently capable graphics card) the user will see a MAJOR uplift in overall framerate and a HUGE uplift in the minimum framerate etc.
Like most possible buying decisions, the equation can vary hugely depending on the needs and circumstances of the person asking the question.
like if you don't already know? if the cpu is not affecting the result then my guess is that it would be SFA, shocking that.

They are trying to highlight the performance differences if that’s what you mean.
At 720p and 1080p, you’ll isolate the CPU as the performance factor, so yes. Making it “look better”
3D cache is an insulator, so it's not like it gets more heat, it's that it stopped insulating cores. There's whole articles out there where AMD employee describes all the bits and pieces they had to do with TSMC to get here (flip the cache to the bottom was one step, but not the only one, they removed loads of insulating silicon in general), from the chip. AMD also finally clarified that in case of older generation it wasn't cache that could've overheated (so interwebs were wrong) but cores, hence they had to lock them down to prevent frying. Cache isn't very affected by heat, it seems.

1080p shows the actual differences in CPUs so is technically correct in my eyes, but, I game at 1440p so would like to see those benches more than 1080p
BUT
look at Steam hardware surveys, 57% of people game at 1080p so reviewers are really showing the most used option so its hard to complain. also a strong CPU at 1080p now will remain strong in a few years vs one that is weaker now, so again, long term its probably a good metric.
For those of us gaming over 1080p, reviews exist that show this, so pay attention to them, its not hard.

I want to see more reviews where the CPU is held back by a huge GPU bottleneck at 4k. The bigger the bottleneck the better so every CPU performs the same.

There's a Polish website that always does very interesting benchmarks of CPUs - they don't use in-built benchmarks, they run games on full details but use their own custom procedure and for CPU testing places in games that stress CPU the most, for GPU the opposite. You can see graphs they came up with (summary from multiple games) in various resolutions here:
https://www.purepc.pl/amd-ryzen-7-9800x3d-test-recenzja-opinia-wydajnosc-gry?page=0,55
It looks much more interesting when tested like that, as differences are much bigger. By the way, you can click any of the CPUs there and graph will change numbers to match it against that.
With their tests in 4k 9800x3D is about 9% faster than 7800x3D, for example. So yes, CPU DOES make a difference in 4k, but not everywhere in the game and usually not with in-built benchmarks, but there's always places in every game where CPU does much harder work.

But the fact every cpu performs the same, but the price can vary wildly, is really important real world information. It could save someone spending hundreds more than they need to. Not everyone is as well informed as enthusiasts.

When you upgrade to the RTX 5090, it will remove some of that bottleneck. Then upgrade to the RTX 6090 and it will remove even more bottleneck. I guarantee that an RTX 7090 + 9800X3D will absolutely destroy everything else.
