If a P-Core thread runs faster than an E-Core thread, P-Core threads finish their task earlier than E-Core threads and need to wait for E-Core threads to finish their task. All previous versions of EmEditor assumed that all threads run at the same speed. This new architecture is interesting because a P-Core runs faster than an E-Core. Since the 12th Gen Core processors, Intel has introduced a hybrid architecture that combines P-Cores for performance and E-Cores for efficiency.
I recently bought a PC with a 13th Gen Intel Core i7-13700.
