Flawed comparison, more apples to oranges. Steam Deck is counted as full system.power while Switch us just SoC. Not to mention that both games aren't equal, consoles get optimized pedal to the metal style, because they are developed for that exact hardware, whole Steam Deck runs PC version that has general OC optimizations, it isn't optimized for Steam Deck only. Plus consoles rarely use one of PC presets, they use custom settings that sometimes don't even match individual options on PC.
And all that just to find out what we already knew, that 2025 is more efficient than 2023 hardware. Like duh, it would be way more shocking if it was other way around. Like whole point of newer architectures for portable systems and low TDP is doing more with same power limits. Though with how you can't really test apples to apples betwen console and portable PC, this also is questionable.Steam Deck dedicated and optimized version for that exact architecture probably would run better. Switch 2 got that, Steam Deck did not.
