    PEOPLE, PEOPLE. Apple does have Marklar going wih AMD boxes, but that does not mean no more PPC. If they are released, it would be side by side with IBM's stuff.

    People have tried to sue Apple over lesser things. A major switch in the platform's direction, foisted on the consumer and development communities without any advance warning, would hurt, a lot. Investors would be very pissed off, potential litigants could claim that Apple misled by ommision. Probably wouldn't stand up, but if they do something like that, then they at least deserve the aggravation of a law-suit. Such a move has the potential to be the final nail in the coffin for Apple.



    As for selling X86 and PPC machines side by side? I don't think it would happen. Once you start selling X86 (or whatever it's replacement will be) you've either admitted that PPC is a dead end, or your making a very expensive "test" of "X86/AMD/Intel/IA-whatever" viability. No one's gonna sign up for the latter, and people will be pissed to have signed on to the former. One, and probably both, direction(s) will suffer as a result.

    I don't think it's implausible that Apple sealed the cases shut; but it's not to prevent the users from finding out what processor is inside. They're shipping them to _developers_, right? If they can execute custom code on the box, it's nearly impossible to prevent them from discovering the contents. The "eBay Red Mainboard" fiasco is probably the reason for the weld job, since it seems to match the current Wind Tunnel board almost exactly.



    Anyway, I think it might be a good idea for Apple to build certain types of machines with different procs inside. Think xServe - people aren't swapping out vid cards and the like in servers, so no worries about drivers. And servers usually run UNIX type apps, like databases which are cross platform (Postgres / MySQL) or are dedicated file/print/web/email boxes. They could say up front, "Don't bother complaining to us about Aldus PageMaker 3.0 not working, that's not what these machines are for." Or think of dedicated FCP / Photoshop boxes. Those users basically run one app all day - besides, their employers might be _happy_ they can't install Snood, Dark Castle, etc.

    I don't really see what's wrong with Apple admitting that different processors are better at different things. The PPC line is better for laptops, sexy desktops, and mainstream workstations. x86 is better for high performance machines, the kind where dissipating 100w is no problem if it saves you 2 hours of rendering time. IBM sells several different lines of proc / OS combinations, and no one seems to think that they are abandoning one type of proc for the other.

    I think that these sealed units have 970s in them...



    The whole OSX/x86 thing is a smokescreen, and Steve Jobs is getting his kicks messing with our (the online Mac rumor forums geek community) collective heads...



    I'll take a dual CPU model, with the fattest OpenGL card that will run in it, and a brace of HD Cinema Displays, thanks...

    IIRC, at last summer's shareholder's meeting, Steve Jobs told the stockholders that Apple would not switch processors from the PPC. He also said that the company would have options after the transition to MacOS X was complete. Jobs said that the PPC had a bright future toward the end of his comments about a possible processor switch.



    A switch of processors within months of those statements after saying that it would happen no time soon would mean that Jobs lied to his board and to his shareholders. He would have denied his shareholders crucial information required to make informed choices about the value of their stocks. Make no mistake--switching from the PPC family to Intel or a clone would represent a tremendous risk for the company. Unlike the switch from 680x0 to PPC, the 680x0 emulator made the transition transparent for most users. There is no PPC-to-x86 emulator. If you think that it is a good move and that Apple will take off when the transition is made, then the shareholders were denied the opportunity to take off with it. Either way, Jobs would have cheated his shareholders at a time when executives at bigger companies are being arrested and carted off to jail for lying to their shareholders.



    Make no mistake about it, this is not trivial. If Jobs lied, the board would be the least of his worries.

    in january the transition is supposively complete...Jaguar will have been out for many months, we will probably be at 10.2.4, and new machines will be Os X bootable only.....

    and secondly....perhaps they have developed and will have ready to release a ppc to x86 emulator that is as transparent as the 680x0 to ppc emulator was.....



    just thoughts...personnallly i don't think they are going "intel inside", but i do think the imb 970 chips will be seen much sooner than Q3 of 2003...i think they will be hightlighted at MWSF and machines will ship in march....perhaps just wishful thinking though......g

    So lets say the 1.8GHz PPC 970 and 1.8GHz AMD chip are available from the Apple store. Is Apple going to charge the same prices (or close to them) for their 3 different models? If so, what's going to happen when someone compares an AMD box from a pc manufacture against a similarly equipped Apple X86 box? I bet they find it'd be almost a thousand dollars less from the pc manufacturer. I'm partial to macs and think OS X is great (although I'm sick of the aqua candyish look and don't like the finder or dock), but I don't think OS X and a nicer case is enough justification to charge a much higher price for an Apple X86 box.



    I've heard in the past that Apple keeps an up to date X86 version of OS X on hand in case something happens to PPC and I think this is good business sense. But this is the first time I've ever heard that they are sending prototype boxes to developers (assuming the NMR's report is right). I wonder when they are going to ship PPC 970 prototypes for evaluation? Is it possible these are really PPC 970 prototypes disguised as AMD prototypes?

    Yes. Apple would not go x86. That architecture is 30 years old, and the PC world may soon change to IA64. If Apple decided to go IA64, that would be another story entirely.



    And Intel will, eventually, get a good IA64 compiler.



    What would be even more interesting would be a "Classic" boot into Windows.

    *scoff*



    IA64 doesn't run legacy x86 stuff well. Why on earth would consumers adopt it? Is it because of the Intel name? Pth..



    Or to run the 64bit version of MS Office. Yea, that's the ticket!

    That's stupid.



    Why do consumers adopt any new technology in the first place? Because it's better!



    As long as there is some backwards compatibility, if the product is a leap forward, great!



    The PowerPC was initally slower than 68k CPUs at 68k code.

    How many freakin years has Intel been working on IA64? 10? They STILL haven't managed a good compiler and it has shown itself to suck so badly that MS, who was originally saying they wouldn't support the Opteron chips from AMD which are x86-64, is fully supporting them in Windows and is planning it's own x86-64 direction.



    Now I realize this is similar to the X on PPC vs X on x86 as there are 2 different processor types, but I don't think Intel is going to win out necc on this one. I think they'll end up having to scrap IA-64 and reverse engineer AMDs x86-64 or figure their own version out quickly, leaving AMD as the sole 64bit desktop chip maker between the 2 of them.

    Um, I think some of you are missing the point here:



    Mac OS X does not care what kind of processor it runs on.



    Once you tweak the kernel (a rather easy job, since it originated on X86), everything else could care less whether it's a PPC, IA64, or Dragonball, for that matter.



    Remember the OS X architecture is designed to keep ALL software away from hardware, instead handing off hardware-contact items to the kernel subsystem.



    The only problem might be Altivec -- IF Apple had never adopted it, Mac OS X would be very portable from processor to processor. Even with Velocity Engine (note, That's Apple's brand, not Mot's or IBm's or Intel's or AMD's), the OS could reasonably be adapted to any SIMD.



    The point is, thanks to the Unixy nature of OS X, it is a relatively easy port from Processor to processor, and that is NO accident.

    every program available for macosx is compiled through ppc machine code, which is not similar or even easily transferrable to x86 machine code. so, the portability of the kernel, and possibly many apps, is nice, but it still means that shit has to get recompiled. just remaking the kernel will only fix the kernel. each app will need a recompile (at a minimum).

    People on here are mixing things up quite badly again...



    Let's - for a moment - assume that the Naked Mole is right. Apple has shipped some test units running Mac OS X and some recompiled applications using AMD processors to testers. (Yes, a recompile would be necessary, but there isn't large porting issues to be solved if Apple has Darwin and Cocoa up and running on X86 and we are talking Cocoa applications, as Darwin *IS* running on X86 today and Cocoa *WAS* ported from X86 to PPC first. Let's just assume that the Aqua stuff on X86 has been kept up at the same time, like older X-on-X86 rumours assume.)



    This doesn't mean that we'll see AMD processors in Macs anytime soon. It means that TEST boxes have been shipped to selected TESTERS.



    Now what if Apple finds out they can do a transition to AMD's X86-64 platform easily? Not marketing-wise, but technology-wise? Let's assume that Apple has the technology to introduce some machines running on AMD processors (whatever kind) in late 2003.



    Steve SAID they like options. Hell, what options do they have if they don't actually TRY these things?



    Basically, Steve kicked Motorola's and IBM's asses with that statement. And if both companies can't deliver competitive processors in a nice timeframe, Apple oughta put their money where their mouth is! They can't wait forever for their AIM partners. So what would be better suited for Apple than to actually DO something about it and prepare those options a little bit?



    Doesn't mean a switch to X86 has to come this Spring. Doesn't mean it has to come in 2003. Doesn't mean it has to come at all, in fact. But to add a bit more fuel to the fire Steve started by saying that 'they like to have options', they also have to test this stuff.



    However, the NMR's rumour is as cloudy as can be, so I don't give it too much credibility. Still, it's only logical.

    From what I know of (electric) welding, MIG, arc, etc, welding a case shut would have a tendancy to fry any electronic components inside. So this part at least is bollocks.

    It could be welded without damaging the components. The motherboard is isolated from the case, and the case grounded during the welding. As long as the electronics aren't touching the arc it would be fine. You can even touch the case while it is being welded and not get shocked.
