The nodes are a fundamental part of a cpu architecture. When designing the architecture, it was based with a specific node in mind. But even that is irrelevant. You cant change the node, but you can change the power limit. And nobody argued that you should test at a low power limit. Im arguing that you should test at the SAME power limit. It can be 50 watts or 500 watts

Yeah, certain architecture details such as the cache sizes depend on the transistor density, the higher it is, the more cache you get.
But there also happens backporting, when a given chip is somehow built using a previous node.

2nd
How can you evaluate a CPU architecture vs CPU architecture and make a comparison between the two, knowing the nodes for both are totally different and both are being evaluated by random low power limit chosen by an evaluator even though both CPUs are desktop segment processors?

side question.
Would you evaluate efficiency and performance of a server processor for instance by the lowest possible wattage the CPU can handle, highest possible, or stock wattage set by the manufacturer on a variety of benchmarks?

Every design has a sweet spot where its performance per watt is highest.
Also, you can compare nodes - transistor per mm squared.

So here is the highest 12900K score I could find. I wonder if the 13900K will be able to beat the single core score here.

Single-core or even 2-core performance should be at a power below the stated long-term/base TDP of 65W.

For MT performance, you should blame hardware reviewers and motherboard manufacturers. The latter especially most often use high or no power-current limits and tons of load voltage (leading to effectively overvolted operating conditions, i.e. voltages exceeding values in the CPU-fused voltage–frequency curve), making default settings far from being true Intel defaults. They are allowed to, since power limits are not a processor specification and any current/voltage is allowed if below the specified limit and temperatures do not exceed TjMax.

Hardware reviewers seem generally clueless about all of this.

If Intel-recommended PL1 (65W) and Tau time for locked processors (recently usually 28s) were actually respected, due to how the algorithm works the CPU would go from 200W to 65W (PL1) within 10 seconds, making PL2 influence on long benchmarks like Cinebench scores limited.

People who want to efficiently use their 65W CPU at 65W no matter what, should tune their motherboard settings accordingly.
the default settings should be default, or either they should allow to select tdp by cooler selection like msi boards.
