So a 10% difference deserves a callout but saying that one console will render the same game at less than half resolution of the other one is speculation (hint hint more than 50%). Which, in addition, is based on some cherry picked data points and benchmarks that are completely misleading.
"For the benchmark they ran it at full ultra mode with no extra settings and THEY compared directly with a PC with an RTX 2080 and a 2950X"
"What that benchmark shows us is XboX Series X produce nearly identical results"
"The PC has some advantages but the performance is on par with an RTX 2080"
Well, I apologize, I didn't watch this particular video, I was running off information of the original article and interpreted it poorly. But this is a good info here.
I was wrong about the benchmark, but that still doesn't change the nature of the my argument.
You are fixated largely on the wrong argument, I'm not saying XSX will run 4K60 and therefore PS5 will run 4K30.
I'm saying if a game is optimized exactly for 4K60 on XSX. Then by default PS5 will run below 4K60. Since the next closest framerate is 30fps, the option is to clip or scale resolution. If your engine does not support scalable resolution, you will clip.
I'm not saying there is a power differential between the 2 GPUs of that amount. I'm saying in the real world and how in the console world things are running fixed frame rates, these types of scenarios can happen.
Performance between these 2 GPUs can be determined through formulation.
But when it comes to retail release and specifications, formulation doesn't apply, we move onto probability and distributions.
If everything was as simple as formulation, we wouldn't have such as many outliers as we do in comparing PS4 Pro and X1X, some of which titles are running 4K on X1X and 1080p on 4Pro. Does formulation explain that? No, it doesn't. But that was the release. We have median values, and 4Pro for the most part performed in the median value with respect tot performance vs X1X. But that doesn't remove the outliers. Which has been my argument all this time. I am "speculating" that there will be some titles that fall into this category, because we've seen it happen before.
There were at least 2000 titles released last generation, we are likely to have another 2000 odd or so. Are you so confident that there is no way outliers could occur in which XSX will double the frame rate, or resolution will be doubled? I wouldn't bet on that, surely not based on the data we have from this current mid-generation. In the same vein, I wouldn't bet against that PS5 and XSX run the same settings either despite the 18-20% advantage XSX has over PS5.
