Rosetta and AltiVec?
Meanwhile iLife and the apps that come with OS X are Intel native, and in theory, anything that states G3-compatibility should run (via Rosetta) too. Also, some apps (like Quake 3 engine games) that SAY they need a G4 will actually run on a G3: it's just that no G3 fast enough existed when the requirements were written. (Rosetta is G3-compatible, but that does not mean limited to G3 speeds.)
Beyond that, we'll have to see! I'm very curious to see whether Rosetta supports AltiVec now or not. Because in truth, I don't demand maximum raw speed from most apps I use: just being able to RUN them--at all--would be very nice. I look at most of the apps I use, and ask myself what I would think if I could run them twice as fast... and for MOST of them I don't care! Mail? Text editing? FTP? Lots of things don't demand max speed. I'd happily settle for them "just running" so that other apps (more and more of them over time) would run far faster. Apps I do care about speed for.
So the rumored AltiVec Rosetta translation would be a good thing even if it lacks AltiVec speed. Do we have that answer yet?
The other half of the question is speed: what apps does Rosetta run... at USEFUL speeds? I'm optimistic: apparently the devkits (which didn't even have real 3D boards) were running some 3D games (like Alice) at excellent speeds in Rosetta. And we've heard other examples too. Rosetta won't run as fast as native--but Core Duo is a faster chip to begin with, and that helps offset the penalty.
If we're comparing Rosetta-on-fast-Core-Duo to native-on-slow-G4, I think we may be pretty happy with the results overall. We'll know soon!
the whole point of the yonah processor and going to the 65nm size is that it consumes less power and thus, can run faster for the same power consumption.
But if Intel used 65nm to make chips that were no faster than the old chips, they would run cooler than the old chips.
Apple has said their pro apps (Soundtrack, Final Cut etc.) won't run--until an update coming in a couple months is out. So don't buy those apps now.sw1tcher said:Now if only someone would put together a list of programs that won't run on these new Intel Macs.

Yes, but they were comparing to past Intel architectures, not to PowerBook G4s.excalibur313 said:Intel was making this big deal about how computer manufacturers could be really creative with case designs because the cooling doesn't have to be as elaborate.
