Geekbench 5 pretended that all multi-core workloads were embarrassingly parallel by running N independent copies of the single-core test across N cores, with zero communication between threads. Geekbench 6 takes a more realistic approach so Amdahl's Law applies and it doesn't scale linearly with more CPU cores.
