Hi, someboy knows what is the controller chip on PowerMacs G5? Apple calls it "Advanced PowerPC G5 System Controller"... but what is the specific model of the ASIC?
Thanks

It's brand new. What's to know? It was designed by Apple for this machine. It might end up in iMacs some day for all we know.

It's a custom chip made by Apple for Apple, and that's all we really know.

Didn't I hear that it was made by IBM side by side
with the G5 chip?

Correction: made by Apple side by side with the G5 chip (made by IBM).
Well, they would have to share data and specs to insure interoperation. One is designed with the other in mind. Can't really do that in the dark. But the controller is designed by Apple.

ASIC is an abbreviation for "Application Specific Integrated Circuit".
In other words, a custom chip built for a specific purpose.
It no doubt has a model number, but it's an Apple chip, proprietary to the Mac and useless for anything else.

Gotcha, but we missed each other still. Apple did build the chip. I don't know who fabricated it. I assume whatever Taiwan based contracter makes the motherboards, but I don't know how Apple outsources their fabrication. It might even be in-house for all I know.
Apple built the system controller, not IBM. But the design obviously requires cooperation to insure they each do what needs doing on the system.
