This would presumably let x86 windows games run on ARM hardware.
This is almost certainly meant for the next Valve VR headset, but ARM has so much better power efficiency than x86 that a future ARM based Deck would be a huge improvement to battery life.
Also see this tweet:
VR games that have already secretly pushed Android ARM builds onto the Steam Store are ran via Waydroid (androidARM to LinuxARM)
VR games that do not have an ARM build on Steam (windows x86) are being translated/emulated via ProtonARM and FEX
is there any ARM chipset out there that can deliver performance on par with the Steam Deck’s CPU
Yes, but they’re made by Apple.
I got a M1 Pro MacBook a couple weeks ago. I’m astonished at how fucking powerful those thing are. An Intel laptop I had with similar specs would start screaming for mercy for any heavy Programming work I’d do. The MacBook just shrugs it off. Fans don’t even come on
keep in mind, for the longest time Intels processors were still on Intels fab. a huge chunk of the efficiency/performance gains was less x86 > arn and more Intel Fab > TSMC. even to a lesser extent, compare the snapdragon 8 gen 1 to the snapdragon 8+ gen 1. Samsung wasn’t as far behind tsmc (compared to intel) at the time and both designs basically are the same chip but implemented at two different fabs.
It also involves how manufacturers decide how to handle price performance. Most laptop manufacturers see any performance lost due to clocking it low bad for sales(so they agressively clock it higher for performance) causing louder fans. Apple takes the opposite approach, where they tune it for noise performance because they control what people see on their graphs (while being misleading, by essentially never including anything faster than it) and asking users to pay top dollar for the top tier fab runs (apple essentially has top cut priority at TSMC) so they always get to see the bleeding edge efficiency nodes/performance before anyone else does at the higher cost to them(which is then passed on to the consumer)
