I was just wandering how many cores/threads rpcs3 will use or uses..
Dolphin uses 2 cores + 1core( for Lle only)
pcsx2 uses 3 cores
rpcs3 will use ?
any idea?

At least as many as the games themselves use, so for high end games I guess 9. 2 PPU threads, 7 SPU threads. And since we are an HLE emulator some things may be able to run on their own thread as well. (If the game just tells the PS3 OS to do something, we can do that in a new thread, possibly, I am guessing this)

Further optimizations for more parallelism may or may not be possible in the future.

why 9 cores ? why 7 SPU ? as far as I know a PS3 game can only use up to 6 SPU, because 7th is used in internal by the OS and 8th is disabled. So it sounds for me like 8 cores.

Yeah, maybe so. I just quickly looked at this. "the PS3 can have at most 9 threads runnings at the same time (2 from PPE and 7 from SPE)." But yes, doesn't mention what games can do.
