Task Manager of prototype Intel CPU shows Core and Logical processor count are the same at 8.

This is still a relatively low end chip if its just 8 cores and a 13500 has 6 + 8 = 14 total so this is maybe a laptop processor. Hyperthreading probably doesn't make sense anymore.

I am curious about why performance cores would go with a no-smt implementation; the die area improvements are obvious, but how are they going to spend that die area improvement to make up the performance gap?

AVX only really affects a small subset of applications, so I can't see that going too far.

A better branch predictor could be a boon, but given how good they are already I'm not sure how they could make up the 50% multi threaded loss.

Perhaps just cramming more physical cores together and a better cache sharing mechanism?

The multi thread performance would be handled by e cores. I guess the trade off for smt is no longer worth it with e cores in the picture.
