> Issue is, it's a pain in the ass to develop for

Agreed,that definetely does sound like a pain in the ass. I've never heard of anything like the ps3's cpu setup. Also as you've said trying to reprogram a game engine to run on such core setups sounds like hell.

> Clock speed doesn't equal IPC

I knew that part. I just recalled a simplistic theoretical equation for calculating cpu time where IPC*Clock speed*Instruction count=cpu time, So i made a crude estimate that ipc must be low. I didn't take into account any software optimizations or how the crytek engine was designed.
