I was curious about exactly how the Intel 12th gen efficiency cores compare to the performance cores, so I wrote a script that runs Geekbench 5 against each individual core. I chose Geekbench for this test because it offers a nice mix of real-world algorithms rather than an arbitrary synthetic mix of computations. Here are the results for an i7-12700h running in an Asus Vivobook S 14X.
Cores #0-5 are the six native performance cores (hyperthreaded cores excluded); cores #12-19 are the eight efficiency cores. Core #0 is the 100% baseline.
Based on these results the efficiency cores are 62% as fast as the performance cores on a i7-12700h.
Note how cores #4 and #5 are faster than the other four performance cores - these are the "favored cores" on this particular CPU die. See Intel Turbo Boost Max Technology 3 for details.
Here is a link to my GitHub repository if anyone would like to run this test on their setup as well. It runs under Linux.
