Allen 8nm is just the minimum resolution of lithographic process on the silicon wafer and how dense the resultant SoC can be (in rough terms).
None of us understand that process as its massively valuable IP, but we don’t need to understand manufacture process just operation of the SoC and as @tkaiser posted we already have some absolutely whopping sized technical references datasheets for the RK3588.
@tkaiser as a test if you OC the OPP does the soc take any notice at all would still be interesting.
The amlogic was not a cheat as likely 10% is likely within tolerance of quoted specs what they where doing is locking the speed with a licensed blob.
The quoted specs was just the standard sales speak as many things are cheats where ever they can legally and presume it was.
The GPU on the S905Y2 seemed to be locked whilst on the a311d clockspeed is locked via a mcu blob.
I guess its the prerogative of the SoC manufacture and wondering even though we can not test GPU does the CPU OC?
