PN64 Angrylion multithreaded question

I apologise for making a similar topic last week at the Windows section but I received no replies.

I cannot find any information about a possible benefit of using a 6 core (12 thread) CPU instead of a 4 core.

Does angrylion multithreaded use an infinite amount of threads or is it pointless after (for example) 4/8 threads?
