Now with proper benchmarks, innit
Mere spec sheets?
Old news, friend.
Asus handheld is both smaller and lighter than the Steam Deck, and build quality hasnt suffered for it.
The Steam Decks extra bulk is also largely accounted for by its own features.
With the Deck, you only get anti-glare on the most expensive 512GB model.
Unfortunately, if its maximum framerates youre after, know that the 1080p display still exacts a heavy toll.

Neither machine, interestingly slash disappointingly, was able to runReturnalat a playable pace.
Still, its hard to argue against the ROG Ally being more powerful on the whole.
As it stands, the only ROG Ally SSD is a 512GB model.
At least the ROG Allys microSD slot is backwards compatible.
With all that in mind, the Steam Deck is better if youre trying to keep costs down.
Same for the ROG Ally, too.
This mode can also damage performance in tougher games, to the point whereForza Horizon 5became downright unplayable.
Anti-cheat systems, mods, and anything else that places nice with Windows will do so here too.
Because, yknow, it is also Windows.
SteamOS, on the other hand, looks and feels right at home on the Steam Deck.
Whether thats worth sacrificing in favour of wide game compatibility, Ill leave up to you.
All the same, that still leaves the Steam Deck as the more affordable option.
As un-gouged as the ROG Ally pricing is, I would say that the Steam Deck is better value.
The question of which portable PC is best, however, requires a more complicated answer.
The ROG Ally is worth its premium, especially when that display is part of the deal.
