Beyond simple curiosity to learn about how and why is there any other serious reason why this reveal may be important?
Does it hinder performance or cripples the product somehow?
Why I see some people write "ha AMD lied to us gotcha" and such?

It's very likely that these are actually Epyc CPU's straight from the factory, and then they lasered off the bad dies and flashed firmware into the chip to show up as TR.
Minimum work, reduced waste, everyone wins !
Except Intel of course, which is losing marketshare on all fronts rapidly...
I really hope those foundries AMD is using can keep up with the demand !

Any way to unlock that stuff in there like back in the Phenom II X3 to a X4 days?

Or maybe two bad ryzen dies with bad cache and two bad zeppelins with bad cores. But I don't think its possible to make working threadripper in that way:)

Instead of making useless comments why they did it , to which the answer is very clear > production optimisation , we should ask are there actually intact 32 cores cpus sold as an 16 core cpus and is there a way to activate the rest of the cores π Since the platform is clearly almost the same as the EPYC platform there will be no surprise if we see up to 32 core Threadripper in the future put against the i9 series.

Dont forget people, that the Zeppelin dies are not just cores, but there is also a SoC on there.
Some wafers may have defects in the SoC part, and they would be totally lost, even if the cores worked.
This is a re-use and minimizing waste procedure, that is extremely cost effective.

Don't forget that with NUMA it's possible to access memory and PCI express lanes linked to another core, via infinity fabric.
So 32 core CPUs definitely possible on current X399, with 2 of the dies not directly linked to the motherboard. Latency will suck yes, but if such a CPU is built, it will be purely for content creators, where core power is more important than memory or IO latency.
