wird die intelversion dan auch dual 64bit?
100%. apple könnte es nicht verantworten, nach den 64er-G5ern wieder einen 32er-chip zu fahren. gaaanz gaaanz schlechte idee![]()
Here's a dirty little secret that surprises more people than it should: Mac OS X is already fairly warped when it comes to 64-bit computing. It works, and it's there if you're willing to jump through a bunch of hoops, but you'd have to be remarkable in your definition of what a 64-bit OS was to give the moniker to OS X as it currently stands. [...]
Now, it's worth noting, Mac OS X isn't really a 64-bit OS. The kernel itself, through a type of 3-card monty is able to address bunches of memory so if you stack your shiny PowerMac G5 with eight gigabytes of memory you can fill it up, but you can't launch Photoshop and tell it to use 6 gigabytes of RAM because the majority of the libraries and frameworks and such are not 64-bit.[...]
And really, not having a fully 64-bit system causes so many problems (in addition to the above) for developers that it just isn't happening. Buying a G5 gets you very little in the way of 64-bit goodness right now, although you do get some goodness from the other enhancements in the G5 for your 32-bit apps and code. And yes, Apple really is behind the curve here, as even Microsoft put out a 64-bit version of Windows awhile ago and Linux has lead the vanguard.
The point is, Apple isn't exactly at the vanguard of 64-bit computing as it is, and that mostly just came along with the MHz bump of the G5 and 64-bit hasn't been all that important. They'll eventually have a fully 64-bit system, probably sooner rather than later, and most developers (even those that really need 64-bit goodness) have chosen to wait for that. When Apple wants to, x86 has it.[...]
Apple's current support for 64-bit is somewhat weak right now, and few developers are actually jumping through the hoops to use it, and while it's unknown which product lines will first receive Intel chips, just as its unknown whether Apple will be pushing out Mac OS X as a fully 64-bit OS by then, or whether or not they'll be using 64-bit Pentiums when they do ship, but if they want to use 64-bit chips, they should be available across all the products lines Apple would want to use them for.
