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.

They are saying SMT for data center. There are no heterogeneous Intel CPUs for that market, right?

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

>>mrheos+RC
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.

Not sure if there are true heterogeneous server CPUs or not, but with Intel Speed Select Technology (SST) you can mimic some similar features. SST allows you to set some cores to be higher base frequency, turbo frequency, etc, in return for other cores having corresponding lower frequencies. Naturally, the cores are not inherently different here, it's just distributing the power/thermal loads differently, so it's not a true heterogeneous system.
