Currently sporting a Pixel 7 with GrapheneOS but i only started to play with emulation this week on it. So i cant give you much of in-depth answer but just some observations. My previous phone had a snapdragon 870 which serves as kind of a reference point. IDK how i really feel about the Tensor G2 performance. It seems to be on par with the 870. Which is totally fine since the 870 was a pretty fast chip. But damn, with that Google is 3 generations behind Qualcomm atleast when it comes to emulation.
This guy on youtube has quite a few videos testing out the emulation performance on the pixel 7: https://www.youtube.com/watch?v=hG6ayegaEzA&list=PLqTxux-zjFRO47ffNrC0ixA6WCSdd9viq I think he even plays the games long enough for throttling kicking in and then mentions it in the comments. I wouldnt click on his links in the descriptions though.
Besides that i couldnt get to run Burnout 3 and Legends on Aethersx2(in menu but crashes before any race starts). Never had a problem with them on my old phone. But i havent looked further into it. Midnight Club 3 runs great though. 3x resolution runs smooth on the first race.
No experience with yuzu yet. Especially with Mali its just better to wait and let things mature a bit. But i dont expect Tensor G2 to be ever good with switch emulation.
On the emulation for android subreddit Mali is a meme. Snapdragon is clearly faster. No doubt. But Malis reputation is almost comical there. Sure your average 5 year old 150$ Xiaomi has a really slow Mali gpu. But a modern flagship with like a Tensor or a Dimensity chip will be adequate for most stuff. No custom drivers for sure and worse drivers overalls. But its not automatically unuseable.
