Well, I will not be as critical until we have retail silicon I guess is what I am saying. I still think it will loose badly to Genoa, MAYBE even Milan, but can't tell now with this test. And unfortunately, the core count will not be equal. Anyway, I think it WILL suck a lot of power if its like Alder lake.
This isn't going to be a desktop part that has to reach high clocks...
Nobody in their right mind would run a server at full turbo anyway.
If we take the desktop parts as a guideline, as you clearly do, the super hot an un-efficient 12900k running at base TDP of 125W uses 5 whole watts more than the 5950x at its default settings...at which point it is about 7% slower in cinebench even with 24 against 32 threads, but also the 5950x is almost 20% hotter than the 12900k, especially for servers better temps will often trump better performance since better temps allow more systems in the same space without changing anything about cooling.
Also if a server has to pay for software by the logical core the 12900k makes much more sense due to the lower core count and still almost equal performance.
Another thing, but I don't know if this is true for server CPUs as well, but intel CPUs are extremely hard to trigger a thermal or any other kind of shutdown on, they will throttle down insanely but you wont have any down time unless you do crazy stupid stuff on it, desktop ryzen just immediately shuts off if they hit the thermal limit which would be ultra bad for servers.
Watch a goof trying to blow up an intel CPU
All these systems ran with the be quiet dark rock pro 4 and the 12900k was 13 degrees COOLER, 67 to 80.
