I would have to add that AMD management has also been asleep at the wheel. They are in the tech business. They ought to have tried to outflank Intel, rather than to take them head on.
For example, they should have jumped onto the Android phone bandwagon and just made a phone. They have a decent brand, and I am sure I would have bought their phone. They needed something that will give them good margins, and CPUs ain't it. Apple showed the world how to beat an 800 pound gorilla. Don't take them head on. Go left field.
Apple made outrageous margins on phone to the extent that they are now way more profitable than Microsoft. Honestly, even though I thought Apple would do well, I never saw that coming.
AMD cannot compete with Intel head on. No one can. You need God money to get anywhere close.
