The performance was never the consideration for Nintendo. They want a handheld that can last a long time, so they will always clock their chips down. You can’t compare 30 watts all the time to 30 watts plugged in, let alone 5 watts in handheld mode.
Steam Decks are great, but lets be real; when you play a big AAA title, even on moderate settings, you might get two hours out of the machine pushing it to the limit at full TDP.
This is kind of a nothingburger story. We always knew Nintendo were not going to scale their machines up to the level of PC gaming handhelds.
I think it’s prudent to be on an older node, using stock that’s more abundant, even if it’s older - especially if it still performs the duties well enough. You’re 100% on the cost side of things, especially considering that Nintendo has never had any consoles that were crazy expensive. Everything was always supposed to be family friendly and therefore family attainable.
I still think battery life is a higher concern for them than sheer power when in handheld mode though, and that’s a key differentiating factor between a Deck and a Switch, besides the Nintendo first-party library and chip architecture. It’s really cool that the Deck is flexible enough to do both high performance and low performance tasks with toggles for the draw.
