Nintendo never makes high power consoles that’s not really their area. So I’d be surprised if this is true.
And what does PS5 equivalent graphics even mean? We just talking screen resolution or are we saying it can push the same poly count. I’d be prepared to accept it might get 1080p maybe 4k on a good day, but that’ll only be on low poly assets.
Both the N64 and the GameCube were built and marketed with performance in mind (especially the N64). Maybe you’re just too young to remember the ads.
Apparently the ps5 comparison is because they ran the same tech demo that the ps5 did 2 years ago. But that doesn’t really mean anything. At this point Nintendo may still be working with a wide range of specs on prototypes before finalizing a decision about what the console will be.
