Quad-cores - Page 2

BirdFuzz · October 7th, 2007

The reason PCSX2 works really well with dual core is because the PS2 has 2 high-performance components that are loosely coupled: EE and GS. Since they are high performance, they need tons of CPU (and GPU) power to emulate --- there is no point in using a separate core for something that takes 0.1% of CPU. Since they are loosely coupled, you can actually run things in parallel, and not have two cores just taking turns waiting for each other. I am far from an expert on PS2, but my impression has been that other components do not match this description.

What people need to realize is that many tasks can not be split into more than one thread w/o a slowdown, or, at best, a negligible speed up.

Go for the Quadcore for sure, I have one and it's great.
