Games "It all began when a young man named George Hotz began to work on the PlayStation 3, trying to gain access to the machine in a way that made Sony uncomfortable. In response, Sony removed the OtherOS functionality of the PlayStation 3 in a mandatory update, and the hacking community was not happy with this decision, resulting in a sort of cold war. PS3 hackers have once again gained the upper hand: Linux has been returned to the PlayStation 3."

For instance, the PS3 can run existing code with a recompile. CUDA requires developers to reimplement code around new APIs.

Actually, no.

The PS3's main CPU is a simple in-order PowerPC core. It's actually quite slow compared to standard PC parts.

If you want to get any kind of computing power out of the PS3, you need to use the SPEs. These are basically vector coprocessors (you have 6 of them on the PS3), which have a completely different programming model than a normal CPU. You can't really just re-compile for the SPEs and expect it to work. Even if you could, it'd be much slower than running on the main CPU. Code has to be specially written for the SPEs, taking their unusual architecture into account.

They aren't quite like GPUs, but they aren't much like CPUs either.
