If I may interject, I think what Redd is trying to get across is that people might be overhyping the machine GPU capabilities when doing comparison with PS4 Pro GPU.
His point is that PS4 Pro is a big GPU with tons of available resources and clocked decently high (For 2016 GPU standards). When people say that Switch 2 GA10F GPU will of course surpass the PS4 Pro GPU *before DLSS (What does that even mean?) if clocked high enough, that couldn't be further from the truth.
He doesn't mean that there won't be scenarios where the Switch 2 GPU won't outpace PS4 Pro GPU. Of course, in some scenarios, Switch 2 GPU will outpace or even do things that wouldn't be possible on the 4Pro due to it being a modern GPU with hardware support for modern features. But, when doing a iso comparison, the goals of each GPU are very different. GA10F is designed to be into a power limited form factor and output 4K content with aid of machine learning upsampling. PS4 Pro GPU was designed to draw 200W+ and to bring PS4 content to 4K with checkerboarding. The former has a leaner GPU while the latter has a fatter GPU. In normal circumstances, the wealthy of resources the Pro GPU has access to mean it should be outperforming the Switch 2 GPU even if TFLOPs are equal.
But, again, for software developed to take advantage of modern featureset, the Tegra will be doing things that are outright impossible on the past Playstation machine. The grievance of @ReddDread is just that people are thinking Switch 2 Docked will be a 1:1 PS4 Pro when things should be much more nuanced. Ultimately, I think someone else description is perfect: Switch 2 is a device that can do the same things Series S can do. Just at slower performance due to the form factor.
