Apple is telling developers that it will be Dothan
You might see Yonah Powerbooks and Dothan iBooks/MiniMacIntel systems released at the same time. That would be a nice way to differentiate the low and high end - low end single-core, high end double-core.
The major factor in "going backwards" would be respinning all the 64-bit hype in Apple's marketing. As a practical matter, OSX is 32-bit today, few people would notice the backtracking. (Remember that recent OSX update that disabled 64-bits, and how long it took for anyone to notice?)
AFAIK, Apple has said nothing about the second OSX Intel transition - the transition from 32-bit to 64-bit. One would hope that they do a true 64-bit implementation, so that GUI and Cocoa apps can be 64-bit.
IMO, however, the fanbois would riot if Apple used a Netburst-based chip....
Apple is telling the developers in the Intel transition program to code their applications for Dothan - the current Pentium M. (see https://forums.macrumors.com/posts/1740048/)wrxsti86 said:Yonah is likely to be the first Intel processor used by Apple.

The current 64-bit support in OSX is quite limited - no GUI app can be 64-bit.wrxsti86 said:Unfortunately, the use of Yonah will return Macs to 32-bit operation. When Apple uses Merom, OS X will return to 64-bit operation.

I think that this would be a smart move, especially to get a line of PM.x86 systems for early adopters and developers. These would be sold alongside PM.ppc systems, and the PM.ppc systems wouldn't be phased out until Conroe and later low-power multi-core multi-chip systems were available.wrxsti86 said:Its likely the Intel dual-core 800 D series will be used in Intel powered PowerMacs. The 840 D series is ideal for editing 1080i HDV.
