This is correct. AMD and Intel CPUs had many slower cores. GB5 made them look better. Apple has fewer cores but more fast ones.
Most applications can't utilize many cores. Thus, usually, consumer applications perform better with fewer but faster cores than many slow cores. Geekbench is a consumer CPU benchmark.
I think you may be a few steps behind, what you're explaining is the rationale for the ST and MT individual scores. This is something all modern benchmark software has.
