They already have a partnership. Intel is already making a profit from it and so is Apple.
They have a good partnership because Apple has options. They didn't choose AMD, but Apple could pull AMD out as the boogeyman in case Intel starts not to listen.
If Intel ever became the only x86 game in town it is likely they would be a very much less friendly partner. At that point, Apple would probably start looking to move. I don't think AMD is going to completely implode but nothing they've done in the last 2-3 years is promoting confidence they can stop the bleed.
Apple even asked Intel to integrate faster mobile graphics into their upcoming Haswell top-end mobile processors,
LOL. Everyone and their mother has been asking Intel for faster iGPU units. This didn't solely happen because Apple happened to ask.
This is also the one area where AMD actually has been competitive with Intel moves. They are still a step ahead with respect to graphics in SoC offerings. The trigger to put the foot down on graphics likely was far more triggered by AMD's ATI buy than Apple introducing a concept to Intel they never heard of.
If the HD5200 solution is a RAM+CPU+GPU package solution I can see how it is kind of inspired by Apple's ARM solutions, but that sort of packaging existed before Apple should up with ARMs. Intel has been packaging multiple dies in to a single package long since before iPhone.
because Apple has a vested interest eating into the desktop as fast as possible with their mobile portfolio. Both know they need each other for this.
Frankly Apple's 13" MBP units need them for mare than "eating into desktops". The Mac Mini ( a desktop ) would be more competitive with it.
It is also the case the OS X needs to be able to do high value things to a broad audicience so that can stay out in front of iOS devices.
I think you´re underestimating the impact that Intel´s x86 products have had in Apple´s line-up over the last several years. For every product that Apple introduced the last couple of years they needed efficient and fast processors.
Not really. Overall PC growth has largely plateaued in last couple of years. Mac growth continued for a bit by carving into share of other PC vendors but they haven't really be growing the pie much. Mac growth has stall ( in part to a
Intel makes products that keeps Mac products competitive. Not saying that are bad products, but what customers want to buy is changing.
Intel even manufactured a custom mobile processor package for Apple´s Macbook Air, because Apple needed that.
Again overblown. There were several other customers who also wanted it. You are correct it wasn't everyone. Apple wasn't afraid to ask.
Apple took up the case of EFI when other vendors were dragging their heels . Apple has helped with the stagnant in the PC market. Vendor spending most of the effort of race to the bottom boxes and knock-offs with superficial differentiating features. I think Intel needs Apple more so to keep the PC market "fresh" with well thought out ideas than these tactical things like triming a bit off a package size.
Intel can also use Apple as a foil against Microsoft dominating the PC industry. So it went both ways.
They want to be at the top when it comes to thinner, faster, more performance per watt/more battery. Apple dumped PowerPC for the very same reason.
They dumped PowerPC because wanted to share processor R&D costs with the overall broader market. Apple could have bought PowerPC designs that did what they wanted. But they would just have to take all the risk. They punted on that.
When Apple helped found PowerPC they brought in Motorola and IBM to the table. It was only when IBM started to become the only option that they punched out. As long as Moto and IBM were competing to provide better options Apple kept going. When that started not to work and Apple was the only desktop variant customer ( there were embedded and big-iron options doing OK) that's when it became too problematical. If Apple had plopped down the money to make it IBM would have built a mobile oriented G5.
There´s no software skills in this world that could compensate the loss of Intel on the manufacturing side. You can code efficient software, but even that has it´s limits.
Apple has to add differentiation on top of what Intel sells. Windows is on top of the same platform and gets all the same benefits. There is nothing exclusive that Apple gets. ( Well maybe if Intel made a custom boot-rom inside the CPU package so that nothing but custom Apple specific chips could boot OS X .... but hackintoshes aren't that big of a threat yet).
If OS X doesn't stay competitive then it is going to shrink to be a smaller and smaller pie of Apple's revenue mix. Too small and they'll just axe it. That has nothing to do with Intel's manufacturing skills.
Yes, they won´t go bankrupt without Intel and they will probably find a way. But staying with Intel is certainly the easier route to take.
Yes. I don't think Apple wants OS X to die off. But it isn't entirely Apple's choice. If customers choose that outcome Apple isn't going to sit there and say "I have to be partner with Intel". Intel is not a major customer. They are a supplier. If the customers are going someplace else Apple will follow them.
