Parallel N64 angrylion multithreaded - how many threads?

I was wondering if there would be a benefit from using a 6 core (12 threads) Ryzen 5 2600 against, say, a 4 core i7 6700.

Not in terms of single thread performance but in terms of multithreading, is there any benefit or is angrylion limited to a fixed number of threads (probably 4)?

Maybe this needs to be moved to the cores section… mods, please do so if needed. I’m not sure if it fits here or there.
