A Price War Fairy Story . . .
 

Once upon a time, there were two stores named AMD and Intel selling widgets. Under normal circumstances, let's say that if you add in all the direct and indirect costs of the widget, it costs AMD $10 to make the widget, and they can charge $11 for it.

While the two AMD and Intel stores were fighting fiercely, there were two smaller stores two blocks away. They were VIA and TSM; instead of fighting these two stores might be quietly working together to get a piece of whatever left over just two blocks away.
