Is the MacBook C2D fully 64bit?
apple leopard site has this to say about the OS
"Since the entire operating system is 64-bit ready, you can take full advantage of the Xeon processors in the Mac Pro and Xserve. You get more processing power at up to 3.0GHz, without limiting your programs to command-line applications, servers, and computation engines."
but i've heard that the only apples that are truly 64 bit are the xeons.
So what is the macbook (and macbook pro's) deal? are they fully 64 bit or not? A 64bit processor on a 32 bit board? Does anyone here know for sure?
Lots of people on the internet just go as far as saying that yes, the macbooks are 64 bit. but i generally don't trust them. all those posts are in random comment sections on engaget or zdnet pages.
apple says about the core2duo
"With its 64-bit processor architecture, the Intel Core 2 Duo can execute instructions in chunks that are twice as large (64 bits versus 32 bits), delivering advanced computational power to MacBook. "
but why are some people so insistent that they are not actually 64bit?
i really shouldn't be this confused.

Re: Is the MacBook C2D fully 64bit?
Probably because they are confused as Core and Core2 may be marketed under the 'Core Duo' marketing banner.
Core2 is 64-bit.

Re: Is the MacBook C2D fully 64bit?
why would apple say that only the xeon c2d processors take full advantage of leopard being 64 bit?

let me rephrase.
Why would apple only say that the xeon c2d processors take full advantage of leopard being 64bit.
You'd thing that they'd want to tell you that leopard makes all their "64 bit" machines faster.

It doesn't make them faster, really.
It's marketing. Feel like you need a totally awesome computer? You must need a Mac Pro or XServe!

simple ... macpro's and xserve are marketed to huge number crunching organizations (such as DNA processing / modeling) that can actually use 64 bit
most of target audiance for say a imac or a macbook would look at
Since the entire operating system is 64-bit ready
and say durrr

A 64-bit ready OS taking full advantage of the 64-bit Xeon processor is not mutually exclusive with the same OS taking full advantage of the 64-bit Core 2 Duo processor.

Re: Is the MacBook C2D fully 64bit?
It would help if we knew where you found the text you are referring to in the first post. Context is everything. If there was no need to talk about the non-XEON processors in the context then it would just be a matter of the scope of content in this instance.

Re: Is the MacBook C2D fully 64bit?
Just a theory but say your apple. You want to sell your high end machines. So you put them in a lot of your adds or like in that link and make people think, "Wow look at that. Maybe I should get one of those because they are 64bit. Better then the rest!" Now real high end users would know. Just a theory so yea its wacky but who knows.

There's lots of pages about leopard on Apple's site.
But, yeah, that page leaves the status of the laptops in limbo. Maybe it was written before the lappies hit C2D processors and was never updated. Could be a simple oversight in advertising copy.

Re: Is the MacBook C2D fully 64bit?
The MacBook C2D makes use of more RAM than the CD, it can also accrue it faster. So I presume the MacBook C2D is fully 64bit.
However, if you're expecting that every application will work as 64bit on your machine, that's probably not going to happen.

Every single Mac Apple has out now has a 64 bit CPU. Period.

I'm not so sure that Leopard uses the 64bit under a 1st gen C2D. (what was the name?) Santa Rosa is something something more 64 bit than a MacBook C2D.
Then there is the question which was wether Leopard uses the 64bit on those chips.
But you seem sure of yourself, so please enlighten me..

Hardware-wise, all Core 2 Duo CPU's are 64 bit capable. The Core Duo CPU (predecessor to the C2D's) did not have 64 bit capabilities. The motherboard does not play a factor into whether you can run 64 bit software or not (although, the drivers would have an effect), but yes, the Santa Rosa platform did support more memory (4GB vs 3GB) than the old Napa platform.
So, the hardware is 100% 64 bit capable, it's up to the software (on a per-application basis) to actually run 64 bit code.
