Comparing performance cores and efficiency cores with each other. And then comparing them with AMD Ryzen, who will win?
In my opinion performance cores are always better than the efficiency cores.
P's are better than E's.
Coming to the comparison with Ryzen. AMD's are far better than any Intel processor in the game of web hosting.
If I am not wrong then AMD also cost more if you want to get them as your processor in your server. So, do the math yourself.
AMD has came a long way. Many just avoid Intel because of the power consumption. And also they are not very good at handling large traffic all at once.
