Or it could be some combination of the above.
There's no way that that's the case, otherwise you'd see uniformly lower performance across the board. Instead, for games that don't take advantage of MAME's multithreaded rendering, you're seeing a performance loss of around 5-8%, whereas for games that do use MAME's multithreaded rendering, you're seeing a performance loss of around 30%. It's painfully obvious that it's because of the extra cores (or lack thereof) and not due to any other factor.
