Intel's upcoming Alder Lake lineup schematics have been leaked:

Just a rumor, and these usually have multiple inaccuracies, so I won't bother reprinting the table here, or discussing it in too much detail, but there are a few interesting things to note.
First, Intel appears to be going full Vishera with the PL2 states. Fortunately, unlike AMD's infamous Vishera processors, these aren't the stock clocks, you have to activate them, and I doubt anyone who knows how to do that will have bought an insufficient CPU cooler, motherboard, or PSU to run it. Still, 228W TDPs are still a bracing figure to take in. Definite throwback to AMD during more desperate times.
Second, notice that the i9-12900K is 16 cores, but only 24 threads; the 12700K is 12 cores, but only 20 threads. Unlike the above, this is a good thing, and a sign of Intel trendsetting in the desktop space.
