AMD won't repeat bulldozer era, it isn't small company anymore. They have resources, knowledge, money, they bought Xilinx which will expand market for them, and battle will continue in 2022 too. And about Intel margins, yeah, ADL is completely new architecture which cost lots of money, and they offered them for cheaper than AMD product, they had to give up much of the profits. AMD have lots of space for price cuts, it is old architecture on mature node with excellent yield so for them price cuts is easier than for Intel, and with first round of price cuts they regain top positions. Based on that AMD don't need to release Zen 3D, or rush with Zen 4,especially not in April which some leaks suggest.
