The sad thing is transformation/turn around of businesses never stacks up finance wise. Its hard since the current business is a "sunk cost", and transformation is seen as a big expense with no additional value. i.e. it just puts you where you are. Its also usually requires understanding a business in full and untangling it which is expensive and usually requires significant changes and/or uplift. Most of the time they will ask - Why not just do what we've always done? Why not just use the old thing that works? etc etc.
Its the reason startup's can sometimes disrupt and take over large leaders in the field with much less capital. They have less to lose, and can just do the right thing for now. In some ways AMD had less to lose.
