I would say the clock speeds are excellent. AMD improved IPC enough that the clock speed doesn't need to be extreme - Look here for the efficiency disparity between Intel and AMD processors.
More importantly, the process has little to do with maximum clock speed, particularly in the comparison between 7nm and 12nm/14nm.
The uarch and density elected to be used by AMD is the dominant factor, and they have absolutely smashed it out of the park in terms of die size and performance. Also keep in mind these dies have multiple use cases from personal to enterprise processors, so they are never going to be clock speed optimised.
I think the die size actually works against amd here though it’s to small a surface Area for heat to transfer away from the die and not being center of cpu. I believe with socket orientation on the motherboards it’s at the bottom part on the cpu so some water blocks are not as effect as they could be.
I know amd did the io chiplet is older no and it much larger then the dies but these 3000 cpu temps doe suffer from the way they are made atm and I hope that amd change the design for future cpu’s When they die shrink again
What we have to remember is Intel's 14nm+++++++++++++++++++++++++++ is extremely mature.
Broadwell (i7 6800 / 6900 series) was Intel's first 14nm CPU, did they hit 5Ghz? 4.5Ghz at best and like a toaster oven.
7nm is brand new, give it time to mature.
That’s the one thing that will go against amd from there road map they want to jump on the latest nm and process though.
From there road map we see ryzen 4xxx being on 7nm uv process so that would be a maturing but then zen 3 proberly called ryzen 5xxx will be on 5nm and so on. I don’t think we will see maturing from amd like we have from intel.
Not saying that’s a bad thing but amd will allways be at someone’s else process and following what they manufacturer at the time . But Nvidia have shown with there gpu and other company’s have done it’s a very good strategy
