Yuzu can exhibit superior performance because the Switch is rocking the Tegra X1 from 2015. Yuzu absolutely cannot beat the Switch with contemporary hardware and/or comparable power consumption.
Oh yeah, clearly I did not read the article well. Still, it doesn’t mean what you think it does.
First, Yuzu is more of an alternative API implementation than an emulator in this setup. The stock Switch OS and API implementation have been entirely replaced with Linux and the Yuzu implementation of the API. Given recent performance uplifts in the Linux kernel, I’m not surprised that Linux+Yuzu beats the first-party implementation.
Second, the use of the word “emulation” in the above thread is really a misnomer: Rosetta 2, Prism and the like all perform what is called dynamic ISA translation. Yuzu need not perform ISA translation when running on ARM hardware.
It is always quite amusing to see a billion dollar corporation beaten in its own game :)
More information/context, if you’re curious:
Rosetta 2 in particular isn’t full emulation because the API is the same for both architectures - it is only dynamic ISA translation. I expect that Prism will be slightly closer to full emulation; there is simply no way Microsoft will reimplement all of the legacy Windows APIs on ARM.
WINE is a great example of something that is also not a full emulator, but for the opposite reason: it does not perform any ISA translation or hardware emulation, but rather only syscall (API) translation.
This is a pretty interesting counter example: https://www.eteknix.com/running-yuzu-on-switch-gives-you-better-performance-than-native-gaming/
But, as others have said, exceptions confirm the rule.

But yuzu was running on the switch in that example. So it was beating the switch on contemporary hardware.

I’m also not surprised and I still find it amusing. The ISA translation is something I never actually thought about in emulation
