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.
ah ok yeah this was more along the lines of an answer i was looking for. I was looking for a hopefully more technical answer.
I assume then that the cpus in the xbox 360 and ps3 (powerpc and cell) didnt have a very high instructions per cycle back then? again i was too young to really experience that era, but the clock speeds in both seemed pretty decent
