Mac Pro ICH
Digging deeper on the Mac Pro's architecture and bottlenecks I 'discovered' the I/O Controller Hub (shortly ICH).
I read that it maxes out at 660MB/s, though I can't find more information about Apple's southbridge.
Is there anyone here who knows more about it and could tell me where I can find more technical details about the ICH? Is it the same for all generations of Mac Pro?
