This fuck is obviously one same chip, why should it be divided into two models?
Arm G57 and G77 are the same architecture, just the number of cores are different.
If 6 cores are called arm G57, 8 cores are called arm G77.
As you can see from the picture,Kirin 820 have 8 GPU cores that same as Kirin 985.
it looks like 820 & 985 are one die, just CPU&GPU frequency is different.
