This just REALLY shows off ARM's major power efficiency advantage over x86 for chip TDP's at/under around ≈20-25W!
Once you go over that kinda power band ARM loses most and eventually all of its efficiency edge (which is why both Intel & AMD have been able to basically completely or near completely eliminate the power efficiency/battery life deficit to Apple's M series Macbooks in 25-45W devices w/ x86 chips like Lunar Lake & Strix Point, as well as why ARM servers are still broadly unsuccessful).
But once you hit around ≈20W or so ARM starts to notably pull ahead in efficiency, with the gap only getting exponentially bigger the lower the power level gets from there! (Which is exactly why x86 smartphone chips in the 2-8W TDP range were always a doomed idea right from day 1, despite Intel's foolishly expensive efforts to the contrary...)
And thus when you compare the 15W handheld mode 8nm Switch 2 to the also 15W OG 7nm Steam Deck (even considering the fact that RDNA 2 on TSMC 7nm is NOTABLY more power efficient than Ampere on Samsung 8nm), the former gets essentially DOUBLE the battery life when running the exact same game!
Otoh for handhelds with a >15W TDP target like the Xbox ROG Ally X, x86 still makes by FAAAAAR the most sense as nothing in ARM SOC land has enough CPU + GPU performance to justify ARM's massive compatibility problems w/ coded for x86 PC titles.
And even if such an SOC DID exist, ARM's power efficiency edge is mostly negligible in the ≈25-35W+ range that these beefier devices are targeting/will mostly be used in anyways, making giving up native x86 support essentially pointless... 🤷
Fitting for cyberpunk of all things to crash at the end. People keep on saying that it got better shows it still s*** optimized.

You're goofy. Just because something uses ARM doesn't mean it will be power efficient. Anyone that knows anything on this subjects knows that Nvidia Tegra chios are not power efficient in the least. Do you know why smart phone/tablet manufacturers stopped using Nvidia? It is because Tegra has terrible power consumption:performance ratio.
I've been getting about 5 hours consistently with Sea of Stars, for what it's worth.
