Of course it will be faster if they replace the efficiency cores with high performance ones.
There's a good chance Qualcomm will beat it on efficiency.
This will probably still be among the most efficient SOC's when it comes out. The new designs may have some improvements, and I'm guessing this is 3nm instead of 4 which was the best previously available.
It's cool that we have an alternative to Qualcomm for high performance on Android.

I doubt efficiency will be much of a problem for the Mediatek Dimensity 9300. This is a beast!
Even with higher efficiency than last year, could it match the efficiency of a small core when doing next to nothing while the phone is idle? Feel like they should've included at least a single small core for that purpose
Performance is important, but efficiency is where it's at!
Arm claims the X4 has 40% better power efficiency than the previous generation.
So it will be more efficient than anything from previous generations.
