The more I look at that methodology an presentation, the less I like it.
According to the chart above the i3-12100F (4P 0E) is beating nearly all AMD CPUs without X3D cache in efficiency. This looks strange considering that the 4 P-cores have to run at high clocks and that should be the worst outcome in efficiency. Idk what is happening there.
There is another more meaningful test with two CPUs locked to 86W and now outcomes are very comparable again. I think that is the key for Intel CPUs: you have to lock them at around 90W to get good efficiency. This will likely force the usage of E-cores and lower clocks for P-cores.
We know that Intel decided to unlock their CPUs to win benchmarks and that will destroy their efficiency at +200W. I think it would be better to sell these CPUs locked to 90W (14700) and 120W (14900) and enable full power via an overclocking option.
