It seemed so far away when, in June last year, Apple announced their two-year transition to Intel architectures; it also didn't exactly add up. At their World Wide Developer Conference, Apple let the world know that every version of Mac OS X since 10.0 has been compiled and running on x86 hardware, so the OS was ready.  Apple's iLife and iWork suites are a great supporting cast to the OS, and those applications were either ready or very close to being ready.  Yet, Apple was telling everyone that they would start the transition by June of 2006 and be done with it a year later. 

Everything started to make sense once Intel's Core Duo launch was scheduled for the beginning of the new year. It was this chip with which Apple would launch, and why not, as it has a guaranteed migration path over the next year.  Core Duo platforms will eventually be able to be migrated to Merom based offerings (the two chips are pin-compatible) and using Core Duo on the desktop can tide users over until Conroe arrives if necessary.  This way, Apple doesn't have to worry about switching to the Pentium 4 and its high clock speeds and then over to Conroe with its lower clock speeds, explaining why one is superior to the other each step of the way.  Apple gets a quick and easy migration to an architecture that today offers similar clock speeds to their G5 processors (at least at the low end and mid-range), and they get to boost clock speed and performance later this year with Conroe and Merom. 

When Apple announced at this year's Macworld San Francisco that they were ahead of schedule with the move, it was most likely more of a nice spin to put on things than truly being ahead of schedule.  The MacBook Pro and the Intel based iMac both rely on Apple's existing product designs, and the software has been ready for months now.  Third party support is lacking, and Apple's Pro applications have yet to be ported over, but if anything, it wasn't that Apple was ahead of schedule, they were simply waiting on Intel.  It's probably better etiquette to say that you are ahead of schedule rather than saying that you are waiting on your brand new, larger-than-life CPU partner to deliver their goods though, isn't it?

Now that Intel's Core Duo has finally been launched, Apple could go ahead with their PowerPC to x86 transition, but there's another problem.  A very smart man at Intel once told me that you should never launch a new microarchitecture alongside a new manufacturing process. With so many variables, things are bound to go wrong, making delays inevitable.  With the Core Duo, Intel not only introduced a reasonably sized change in microarchitecture, they also made the shift to 65nm on this semi-new architecture.  The end result seems to be that availability of Core Duo processors and chipsets just isn't all that great.  In fact, unless you are a Tier 1 OEM or ODM, we're hearing that you aren't getting Core Duo chips until sometime next quarter!  That's getting dangerously close to the launch of Conroe and Merom, making Core Duo seem very much like a temporary solution. 

With limited supplies, all of Intel's partners were limited in what they could bring to market based on Core Duo, and when.  That's why one of Intel's strongest partners, Dell, made their first Core Duo product a higher priced 17" model that would sell in lower quantities than a lower priced mainstream solution.  And it's also a big reason why Apple's first Intel based products are what they are, and why we are also not finding the Core Duo in a revamped $400 Mac mini today.

Curiously enough, Apple was able to secure large enough quantities of Core Duo to stick in their iMacs before any PC vendor was shipping them in a notebook.  So, Apple's quantities are really small enough that they could operate well within Intel's capacity at this point, or Intel gave them some preferential treatment - potentially as a house warming gift to commemorate the new relationship. 

Then there's the issue of third party software support; the problem is that in the grand scheme of things, Apple is still small fish in the computer industry, and thus, their partners like Adobe and Microsoft are still not ready with their Universal Binaries; although, the transition was announced over six months ago.  So, today's Intel based Macs have to rely on slow binary translation for full software compatibility.  The other problem is that even smaller partners like Aspyr aren't quite ready yet either, so we can't really answer questions like whether or not the port to PowerPC was the reason that Doom 3 was so slow on OS X yet.  

While it's easy to argue that Apple had always planned to have Intel based Macs out as soon as Intel launched Core Duo, it's really tough to say that the transition is ahead of schedule if major software support isn't there (even some of Apple's own applications won't get support until March).  These first-generation Intel-based Macs are more like public beta tests rather than final platforms; while the hardware may be complete, as you will soon see, relying on binary translation to run any non-Universal applications isn't the most pleasant thing in the world.  However, Apple isn't forcing the new platforms on their customers, as you still have the choice to purchase the PowerPC G4/G5 based systems at the same price if you desire. 

The new Intel based Macs are selling though, despite the early stage of the transition.  And they are selling to whom you would expect: the early adopters, the Mac enthusiasts, those who need a computer today and won't upgrade for a very long time...oh, and of course, some may find their way into my hands.

    I have already preorded one (did so on the day they were announced), but now I am having serious doubts about keeping the order (does not ship until the 15th). The only thing that really worries me is if Apple will release new MacBooks when Intel releases the Conroe processor. I would think by that time (fall?) they would have most of the programs ported (i.e. Photoshop) and then an even better processor to run it with. I have been waiting so long for a laptop,...decisions, decisions. Reply

    I would say you should tough it out for a bit. Like Anand said, this is basically a Public Beta test. Kind of sucks that Apple brought out a 32bit version of the OS considering that it could've been x86-64 native if Apple had waited for a couple of quarters. Then again, it makes no difference if the OS is not 64 bits yet, since a 64 bit version would be able to run 32 bit apps anyway. Reply

    I wonder if Rosetta itself doesn't take advantage of multi-thread... Reply

    Wait, doesn't X1600 use H.264 decoding on hardware?? Reply

    It does if the drivers are set up to use it properly. Given that Windows users only got this about a month ago I'd say it probably isn't doing that yet on Macs. Could be, though. Reply
