Intel is currently a customer of ARMH and uses some of it's technology in controllers for SDD's. It's not a question of "if" Intel would ever make an ARM processor, they already do. Though Apple may not be out front in new innovation introduction they still seem to have excellent follow through. Windows 8 was the first step of Microsoft to offer one operating system that ran from PC's to smartphones. It was flawed by having it come out on two different platforms. Apple will probably not make the same mistakes. They've made no secret that their OS and iOS platforms will eventually merge. They just need to start taking the steps to make this happen.
The smartphone is currently a lighter version of a PC. Eventually it will be a PC. The hardware is heading that direction. In the short term yes there are the issues of doing business with Samsung who is starting to beat Apple at the very market it developed. Long range there is the vision of having smartphone that are actual PC's entrenched deeper in people's everyday life. Perhaps the future innovation for Apple really isn't about the next big idea but instead enhancing prior innovations to fit even more seamlessly into our lifestyle.
I can see a deal but Intel will never build an ARM chip in its factory. Apple has long been rumored to want to build their own chip. I have posted this before. Most likely is they will design their own chips and have Intel foundries build them for them. This makes a lot of since for both companies.
Yes, Steve Jobs would have done this, it was part of his vision. And the iPad Mini wasn't anywhere in his vision. But the company has moved on from his vision and they are too scared to rock the boat. Tim Cook is worrying about sinking stock prices, porting to ARM64 would be his death nail.
Intel will make the A processor for Apple, at first. Then they can start collaboration long term about which processors make the most sense. Heck, it may even be a propitiatory processor. Intel/Apple has some interesting joint projects like Thunderbolt. Apple and Intel have thus far played fairly nicely together, better than they have with Samsung.
And, in your mind, Apple is going to keep pushing its processor design going head-to-head against Intel?
Can Apple stay ahead, or at the very least, have competitive performance vis-a-vis Intel especially with having to manufacture the processors at TSMC or Global Foundries? And how long can they keep it going...and at what cost?
