Do you have an AMD press release stating current Turin processors are on N3E? Google AI is saying some of the Turin processors are on N3E (highest end chips) and others are on N4P. That's AI but I always thought all Turin processors would be on at least N3.

The classic (vanilla) Turin CCDs are on N4P, same as desktop. Turin Dense is on N3E.

In AMD press release, they only mentioned that these processors use N3 and N4, without specifying the specific iteration of the nodes.

There was exactly 1 reference I could get from googling this:

According to AMD, the CCDs on this chip were fabbed on a 3nm process (undoubtedly TSMC’s), with AMD apparently looking to take advantage of the densest process available in order to maximize the number of CPU cores they can place on a single chip.

There is also Tom's, but not sure how reliable they are:

The Zen 5c models employ up to 12 3nm CCDs with 16 Zen 5c cores per chiplet paired with the same I/O die.

It's as others have stated. Dense is on n3e and desktop and standard Turin on n4p

I have 8 Zen 4 desktops. It faster than those, takes less power and runs cooler, so in my opinion, even the desktop it is still a winner.

Each to his own. If you don't like it, buy a failed and degrading raptorlake.
Then again you are well aware you are niche within a niche with your 8 zen4 CPUs and same goes for your avx512 use case. Its only marginally faster outside of that specific use case and few other, mostly server-like loads, taking less power and running cooler is bit debatable as well. Bottom line, your perspective is different, and yeah, absolutely, to each their own. Not being enamored with Zen5 does not mean one has to be hasting to get Intel, in my case i will simply hold on my 7950x most likely. 9950x3D might still sway me, though, if the rumors/leak about clock parity with vanilla chips are true.
