Probably thermals, at ~3W/core TDP, 192 cores is gettingg close to 600W to dissipate from a single socket, which is beyond all off the normal heatsink/watercooling solutions I'm aware of

Yeah, that it plausible, though it seems like they could just run the cores a little slower.

There are some pretty interesting cooling solutions in development. Will be interesting to see which ones become economical enough for mass market use.
