The most of interesting part for me is the acked that dropping SMT was a mistake. I wonder if this means the end of E and P cores.

SMT leads to some nasty bugs. Some customers already turn it off due to security concern. Better adding real core(E cores) than SMT.

Plenty of computing uses don't run third party potentially malicious code.

SMT, implemented well, can significantly increase execution unit usage in the face of memory latency.

Now, if it makes business sense to have cpus with such a major functionality that is only useful for render farms and other compute clusters is another question.
