I doubt there's any benchmarks on the Core Duo Mactels for the time being, since the x86-based core client has yet to be optimised/universal (correct me if I'm wrong)....
cause I'm still pondering between a PPC-based Mini and an Intel-based Mini for a 24/7 cruncher....
Which kind of puts the lie to the assertion that this was about cost/performance.
Paul,
What I read when the impending switch to Intel was announced was that the big factor was availability, quantity. The reasoning you've expressed would have put the lie to the move, had performance or cost been the goal.
Michael
The main reason Apple gave was performance per watt, and they showed a graph that put the G5 in very bad light.
And indeed, the Core Duo does use less current than the G5, but when they announced this deal, AMD had much better performance per watt than Intel. As it stands today, I think we can call it a match (performance per watt comparing the Core Duo to an AMD chip).
All in all I think the main reason was the financial incentives that made them go Intel.

Yes, the quantity issue--particularly regarding the then-top-of-the-line 500MHz+ G4s--was what prompted Apple to drop Motorola as their primary CPU supplier in favour of IBM a few years ago, but AFAICT is a less important factor in phasing out the PowerPC. Note that the changeover is beginning with the laptop and all-in-one consumer models, where power consumption and heat dissipation are most critical; the mini-towers, with their elaborate cooling systems, will continue to house RISC CPUs for some time.
I've got an Intel Dual Core Mac on order (so does Bernd) so we can start building and testing an x86 port for OS X.
Sounds good. I know that we have a few team members with the dual core Intel machines all ready, and they are anxiously awaiting someone to produce a science app compiled and hopefully optimized for it. I presume you are looking to do a universal binary that will run on both PowerPC and Intel machines.
Some BOINC projects will run under Rosetta (Apple's Rosetta, not the project) but they are quite slow compared to the PowerPC science apps. (or so I have heard)

Sure. If you want to justify a position you can always come up with a way to "prove" your point.
And, as you said, AMD is better across the board on performance per watt, but not on performance per watt per dollar kick back ... :)
Color me cynical ...
