Nah, they already technically can implement what they did with Zen2 on PS5.I wouldn't be shocked if it wasn't some sort of hybrid between a jaguar derived core and the construction core shared FPU layout.
The current rumored specs for Big.Little appear more or less like this in my opinion:
Small Zen4 cores with 128-bit SIMD and big Zen5 cores with 512-bit SIMD.
Zen4 4-track on 3nm => lower leakage, same frequency capability (smaller FPU requires less current)
Zen5 5-track on 3nm => higher leakage, higher current capability (to feed larger FPU), thus higher frequency support at low/mid SIMD capability.
8 Zen5 cores(Big core CCX), 4 Zen4 cores(Small core CCX) => similar strategy as Apple.
