Yes, the 10900k as the biggest 14nm consumer chip was a power guzzler and is bad compared to Intel/AMD/Apples current line up on new processes.
November 2020 the m1 mac mini was released... September 2022 was when Zen4 came along, the next CPU to use the same node. Nearly a full 2 years.
Cinebench scores... The M1 Ultra got 24189 multithreaded... not that impressive but its tdp is 60w... at 65w the 7950x (eco mode) scored 31308 in the same test, down from 38291 at full power usage (170w).
It will be interesting to see if apple pushes for another exclusivity deal with TSMC for 3nm.
It’s pretty much guaranteed as it’s part of the deal Apple has with TSMC. They bankroll a significant part of costs for a new process node, in exchange they get exclusive access to the node for a number of years.
