Intel, without admitting it, continue kind of tick-tock uarch development.
A core with major uarch update followed by core with small updates when followed by large uarch update again.
GoldenCove/RaptorCove->RedwoodCove
LionCove->CougarCove
PantherCove is big uarch change with large IPC and APX/AVX10 and more
For Client the 'Lake' names correspond to SoC which is developed orthogonally.
The development cycle for Core and SoC doesn't match, SoC is shorter as result PantherLake SoC featuring non-PantherCove core. Yes, names are confusing :(
