Mac Pro ICH

post #1 of 7
Thread Starter 

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?

Read and be wise.

I've read it already long ago... No mention of the Mac Pro.

So apparently I'm not wise enough, that's why I ask it here...

 

Anyone who can provide me info about the ICH in the Mac Pro?

Seeing your name all over the places that one would search for this info I presume you already have read this, but in case not:

Enterprise Southbridge Interface (ESI)
The North Bridge and South Bridge ICs are connected by an Enterprise Southbridge Interface (ESI) bus, a high-speed, bidirectional, point-to-point link supporting a thruput of 1 GBps in each direction.

But that info is from 2008 and from a retired doc, o no, I don't know for sure. Sorry 'bout that.

Thx, I've indeed asked this on other forums.

 

Theoretically (= following that document) should it reach up to 1GB/s, other report it practically goes up to 660MB/s, or 800MB/s.

So I really don't know what to follow...

Mail the owner of this site: http://macperformanceguide.com

He's very kind, responsive and knows stuff like this. I wouldn't be surprised if he not only knows the answer, but can give you solid advise on how to configure your Mac Pro.
