Because you criticize Apple for doing stuff themselves (leaving google as you said ?), so A6 was a point about how making more stuff yourself is making better products. Because despite they are not producing it, it's all internal design now that Samsung is not able to compete with.
That's my only point.
But the A6 and others in the apple products are NOT internal design. It's like having a custom race car built for your specs. You cant say that you built it yourself, McClaren or Ferrari did. When Ferrari comes to you and says "Hey, we have a V10 or V12 turbo, but the V12 turbo costs more" and you then select the higher $ option, IT DOESNT MAGICALLY MAKE YOU THE DESIGNER.
What apple is doing is saying "Hey, our last car was great when we told Ferrari to put in extra horsepower and that we'd pay the costs because we think its worth it. So NOW we're going to build the racecar from scratch. What does Ferrari know about racecars that we cant figure out by stealing an engineer or 2?"
Thats my point.
The A___ (whichever #) are custom chips, not in-house chips. There is a difference.
Any one of these chip fab plants could make a faster speed, more # of cores, more cache chip, but they are making business decisions that those chips
would be more expensive than what they anticipate their customers (samsung, htc, sony, etc) would be willing to pay in general for their intended products. Apple just said they'd front the cash to allow them to build a higher spec processor. Apple didnt design it.
