Yeah, thats what I meant. Microsoft overshot with the One X, and it's design is creaky (GCN, Jaguar, HDD), but it's performance is not - it's 1.5x the raw GPU performance of the Series S. Update its architecture, and you've got a machine that could keep pace with the PS5.
To answer
@Concernt - it's going to underperform the Series S. It's not a GPU question, it's everything else. Those ARM CPUs are remarkably efficient, but there is no way you can get up to matching the sustained performance of Zen 2, with 16 threads, clocked out to nearly 4GHz. And while RDNA isn't as memory efficient as Ampere, Series S still has 2x the memory bandwidth of Drake.
Even if Nintendo decides to match Series S FLOP for FLOP, it will underperform Series S on many games because of these bottlenecks. And if you push docked mode that far, it starts affecting handheld mode too. If the gap between the two is too large, either docked mode has wasted power (because devs target handheld) or handheld has severely sacrificed games (because devs target docked)
Try to close that gap on the handheld side, you kill battery life and run hot. Try to fix
that with a big battery and fan, and you've got SteamDeck with it's huge formfactor and screaming fan.
I think the smarter move is to keep the GPU better balanced against the rest of the machine, and keep handheld's performance gap about where the Switch already is. If I had to guess, I'd say that 3TF is about the peak there.
All that said: Series S doesn't have any exclusives! There are zero games on the market built from the ground up for its level of power. Microsoft is under increasing pressure to drop the rules which require that Series S only differ from Series X in visuals. Meanwhile Nintendo is going to be crafting exclusives for that 2.5-3TF box which are built for DLSS and Nvidia's superior RT solution. [REDACTED] is set to age better when compared to the Series S across the generation. I don't think that's in question
