The 14400 C0 and the 14600 are the only ones worth even looking at, after that skip GO and head straight to a 14900.
14600K might be better binned but the difference will be negligible, and the 14700 series continues to be the ugly duckling of the family.
Late 2024 for 8000 series.
Lets say mid 2025 for the 8000X3Ds
By then PantherLake will be ~6 months away......what exactly are you getting at?
I know the release schedules of CPUs, theres a better one on the horizon constantly.
