AMD's 90nm Processors to Dissipate 105W?

If so, That's comparable to what's been reported for intel's 90nm CHMOS Process. I wonder if the Partially Depleated SOI Process is running out of steam? If so, then the industry would need to move to Fully Depleated SOI pretty soon. Intel has announced they're working on that, so it will probably be their first SOI Process. Possibly at 65nm, maybe even with strained silicon. Is AMD doing anything in that direction?

This might also explain why intel didn't go with Partially Depleated SOI. If it was only effective for 1 Process, and significantly less effective for a 2nd, then with intel's Scale of Manufacturing, the Investment return might not be there. Better to try and stretch the CHMOS Process, and spend your R&D on Fully Depleated. Which seems to be exactly what intel did.

YB -

According to currently available details, maximum current (IDD) of future 64-bit processors from AMD will be 80A, while maximum thermal power will be 105W.

Boy that Smolderon is going to be one hot chip!

Could be dual-core. My guess is that those 90nm chips in H2 2005 are the dual-core chips we've been waiting for. I'm pretty sure AMD made K8's optimized for process nodes smaller then 130nm. It would be hugely embarassing for them to have a 3GHz 90nm product at about 100W.

I think we all remember when someone from AMD i forget who) said that they'd go dual core before doing SMT. Then again, it could just be PR speak.
