My XBox 360 vs PS3 comparison (mostly technical)

[shams]

I haven't followed this thread to date - and have no time or intention to do so.

But two things caught my eye:

1/ I was pretty sure SPU 8 was *completely* disabled as part of the manufacturing process - to keep die sizes down, and the unit itself more stable (and less power drawing). I find it hard to believe that its there in some form of redundancy state.

2/ Has there been ANY mention of the system resources that each OS gobbles up? From what I understand the PS3 reserves at LEAST one of the SPUs - plus an arbitrary amount of general CPU cycles for the OS. And depending what is running, up to 60-100MB of system RAM?

(the 360 uses a fixed amount of 32MB of RAM, and minimal cycles while a game is running?)
