No. Results from a scenario you'll never experience fail to answer the question for which benchmarks exist: "if I purchase this chip, how much benefit will I see?" The "real difference" is what you see in the real world.
Again, this is where you're wrong. CPU tests aren't made to answer one person's quest of "how this CPU would perform on my build?". That is absurd, do you expect every reviewer to test every single combination of CPUs and GPUs in existance for your convience? Or do you expect reviewers to adopt your personal build as their test benches, to the detriment of everyone else? Either way you are delusional.
That's not what CPU benchmarks exist to answer. What they exist to answer is "how do these CPUs compare in gaming performance objectively, with GPU bottlenecks removed". That's the only way CPU tests can ever provide meaningful information. Then, if you wnat to know how they would perform on your particular build, you cross-reference it with tests of whatever GPU you have.
Again, suggesting reviewers do 4K tests just to show a bunch of CPUs artificially tied due to a GPU bottleneck doesn't help anyone, it's just lunacy.
You're literally admitting my point: "yes, THIS test tells me nothing. I need data from an entirely different test to know how the chip will perform."
Again, you couldn't be more wrong. The actual answer is "this test tells me exactly how this chip performs in an objective manner, I need data from a different test to know if it makes sense to pair it with my particular GPU".
The idea of a test that answers how it would perform on your particular build is ridiculous. If the test were tailor-made to show performance in your eprsonal build, that test would be useful to you and useless to everyone else. The only way a CPU test produces results that are useful for everyone is if you remove GPU-limited scenarios entirely by testing at low resolutions with the best GPU available.
Ouch! This is an even worse mistake. Yes the 3700X certainly DID grow faster. But there was nothing "magical" about it. The second test was done on entirely different software.
Software in late 2024 is optimized for a different instruction mix than software from early 2019. As just one example: the 3700x natively supports AVX-256, while the 2700x only does in slower "double pumped" mode. This didn't matter in 2019 as not one game engine supported AVX-256. Once games supported it, a gap suddenly opened.
Except, once again, that is complete nonsense. Nothing changed in the software between 2019 and 2024. You can see that by looking at the low resolution tests, in both 2019 and 2024 you get the exact same result, the 3700X is a bit over 10% faster than the 2700X in both cases. That wouldn't have been the case if the software changed. But it was, the >10% advantage of the 3700X was always there, even in 2019.
The only thing that changed between 2019 and 2024 was the GPU. In 2019, a 2080 Ti was not capable of showing that >10% difference at 4K, because it wasn't fast enough, so the 4K tests were GPU-limited and that obscured the real performance of the CPUs. Fast forward to 2024, now the 4090 exists. And lo and behold, testing both CPUs again with a 4090 now shows the exact same >10% advantage for the 3700X that the 2019 low resolution tests showed. The advantage was always there, even at 4K, the 2080 Ti just wasn't fast enough to show it. Remove the GPU bottleneck (either by waiting a few years so the 4090 comes out, or by lowering the resolution) and the advantage appears.
The example you should have chosen were chips from the same generation: 3700x compared to 3900x, as their instruction sets match. In 2019, the chips were effectively tied, and in 2024 they were STILL effectively tied ... even with a new $3000 video card. So why on earth would you pay the extra $150 for the higher-priced chip?
That's completely unrelated to the topic at hand. The 3700X and 3900X are tied because past a certain point (6 to 8 cores) game performance doesn't scale with core count. You still see the exact same thing today, the 9700X is barely faster (like 5% to 10%) than the 9600X despite having 33% more cores. And the 9900X/9950X are not any faster than the 9700X no matter how many cores you add. That's just the nature of games, it has nothing to do with resolution or GPUs. You pay the extra money if you need the productivity performance, otherwise buying more than 6 to 8 cores for gaming is pointless.
