Apple Switched Chips Too Soon?
Ctrl+Alt+De1337 writes "C|Net is reporting that IBM has announced a method of altering silicon that will allow its next generation of Power chips to run at speeds between 4 and 5 gigahertz, and consume less power as well. From the article: 'Instead of just making transistors smaller, IBM came up with a process to alter how silicon behaves by placing a layer of insulator underneath a layer of silicon less than 500 atoms thick ... The higher speed of the Power6 will be achieved with existing chip manufacturing technology that etches transistors only 65 nanometers wide, several hundred times smaller than a human blood cell.' These won't be out until 2007, but it still raises the question: did Apple jump the gun by switching to Intel?"
Who says Apple won't switch chips again? The current relationship isn't all roses, despite all we have heard. Apple won't put those retarded "Intel inside" stickers on their products.
And, it would seem, the Intel core duo is full of serious bugs which Intel doesn't really care about.
SOI is nothing new. It's been around for decades for radiation hardened ICs used in space and military electornics. The only news is that it is now being considered for large scale commercial production. IBM has been hinting at a transition to SOI for years and rest assured that Apple planners were well informed of this when they made the decision to switch.
I am becoming gerund, destroyer of verbs.
I thought the major impetus for switching to Intel was the supply and timely delivery of the PowerPC (or lack thereof). IBM was not willing to meet Apple's requirements. There is no guarantee they would meet them with this chip, either.
So no, Apple did not move too soon.

And the Cell processor is almost as pie in the sky, until there's some real information about the Cell everything is just conjecture and hope.
Anyone who whines about being modded down should be.
Technically, didn't they have two before? IBM and Freescale?

If you're not outraged, then you're not paying attention.
Apple switched because Intel offers a better deal right now.
I seem to recall it was also a matter of supply problems: IBM couldn't keep up with Apple's demand, while Intel is (apparently) having no problems doing so. In this case, switching back to IBM would just mean inviting this problem back.
Its not implied - its stated. Look at Steve Job's words at the keynote where he announce the intel macs Maybe they can go back - but Steve sure as hell abandonded PPC during the keynote.

Because, up until recently (2004 or 2005), the PowerPC still was a better performing chip (and the G5 is still better in many ways). The G5 came out in 2003, and it knocked the socks off of any Intel offering at the time. However, the PowerPC G4 was left to get old and rust (As much as I hate the x86, I will admit that the G4 performance sucks in comparison to the Pentium M and Solo/Core Duo), and they couldn't fit a PowerPC G5 processor into a laptop, which is Apple's bread and butter. I would much rather have a PowerBook Core Duo^W^W^W MacBook Pro than a PowerBook G4 (even though I would much rather have a PowerBook G5 than a MacBook Pro if the G5 existed).
Apple's switch to Intel is about performace per watt. The G4 is getting too ancient compared to Intel's offerings, and the G5 isn't designed for laptops and other small-form computers (like the Mac mini, for example).
It sounds like that to me too. It also sounds like strained silicon, so maybe a combination of both. (wiki says stretched, the IBM guy says squeezed)
"You literally can squeeze silicon, and thereby give it properties to make it faster. The thing that is making it run faster is not just that it's smaller but because you're changing its basic physical properties," Meyerson told Reuters in an interview.
http://en.wikipedia.org/wiki/Strained_silicon
Strained silicon is a layer of silicon in which the silicon atoms are stretched beyond their normal interatomic distance. This is accomplished by putting the layer of silicon over a substrate of silicon germanium (SiGe). As the atoms in the silicon layer align with the atoms in the silicon germanium layer where the atoms are farther apart, the silicon atoms become stretched. The electrons in strained silicon move 70% faster allowing strained silicon transistors to operate 35% faster.

Given Apple's reputation for the following:
/one/ processor to /another/ - regardless of vendor - on how well they could do so /seamlessly/ for them and their customers, developers, and ultimately end-users.
/announcing/ (not releasing, pre-releasing, spec-ing, /announcing/) a new processor based upon relatively untested production technology, not having been 'shaken out' - locked in on one supplier. And development & revision & 'shaking out' of this technology is out of Apple's control.
/want/ to hitch itself & its reputation to this?
A: Quality products,
B: High-quality and responsive technical support,
C: High profit margin on systems they sell,
D: Doing massive amounts of R&D and testing on the (Computing) equipment they sell -
AND, given that Apple actually has a grasp of supply-chain necessities and economics,
I'd say the view of them being caught "unawares" or "switching away too soon" are too simplistic.
Apple has the customer loyalty and following they have amongst their rabid geeks due to such things as being able to trace a particular issue to a particular revision of a particular card - and developing a fix for it, literally on receiving less than ten reports of the incident, in a matter of days.

Here, we have IBM
And you're saying that Apple might actually
To whit: You picked up that 802.11g box too soon, son - dontcha know UWB is right around the corner?
I seem to recall it was also a matter of supply problems
That, and the impossibility of getting a G5 into a laptop.
Apple probably lost a billion dollars or more every quarter since the G5 came out, because of supply restrictions. It's a fine CPU, but we just couldn't get enough of them.

Not vaporware, just bad reporting. IBM's indicating that the chip will use SOI and strained silicon... if the reporter is too daft to realize that's unrevolutionary, whatever.

Actually, chips for Apple accounted for less than 2% of the capacity of just one IBM fab. IBM's tech division (which does chip fabbing) accounted for less than 3% of IBM's total revenue. That's a really small piece of IBM's global business. It's kind of like an oil company losing one gas station...not really gonna hurt them that much.
[RIAA] says its concern is artists. That's true, in just the sense that a cattle rancher is concerned about its cattle.
SOI just makes the chip run cooler.
They are talking about strained silicon, which makes the electron mobility larger in one direction. Intel, in fact, is working on that too, as are others.
While not GPL, Apple has released much of the source code under APSL.

There are two parts to that question: "...went with a 32-bit part" and "...went with an Intel part".
I have no information on why Intel was chosen. Plenty of people probably have their own theories about that.
Once Intel was chosen, however, at least for the MacBook Pro, a 32-bit part was the obvious choice if you don't want a Pentium 4 (e.g., too much power, too much heat) and want to ship machines before Merom ships; it's not as if the PowerBooks were 64-bit.
The iMac might not have the same power and heat concerns, and the previous version was already 64-bit, so perhaps a case could've been made for using an EM64T P4 there. I'm not a hardware or business guy, though, so I'm not sure whether that would've made sense or not.
In any case, as the next-generation x86 chips from Intel will be 64-bit (if Paul Otellini wasn't lying in his presentation at the Intel Developer Forum, where he said
showing 64-bit OSes running on Merom and Conroe prototype boxes), so any Macs with next-generation x86's will have 64-bit processors.
Unlike the transition from 68K to PowerPC, the operating system itself is running native in x86 assembly. When Apple transitioned to PowerPC, they rewrote less than 5% of the OS and added the Mixed Mode Manager and the Code Fragment Manager and then shipped it. The system was quite often running in 68K mode. Over time, they made more of the OS PowerPC native. Thus, Mac users got used to equating an OS update to mean "faster system" while in the Windows world the opposite is true.
This time, the OS is written in a high level language and has been maintained in X86 for years.
I think the one serious problem with this scheme is that they think they can drop support for Classic. I think more people use Classic than they think.

Call it unfortunate naming, but these two processor families don't really have much in common (other than possibly some marketing material). A POWER processor is the stuff dreams are made of. See http://www-03.ibm.com/systems/power/. A PowerPC processor is the stuff printers are made of. And until recently; Macs.
As a long-time Unix guy, I have to say I don't see that much of a difference between them. Maybe if you're writing device drivers or need to output PDF, yeah, but they're all pretty much POSIX Unix systems. They're similar the way Solaris and AIX are similar, or BSD and Linux.
