Yeah, Intel reacted four years ago to a CPU that came out a few months ago.
Haswell is a reaction to the tablet market.
The first iPad was released on April 3, 2010
Currently, it is 2013.
Four years ago was 2009, and 2009 occurred before the iPad was released.
Something is wrong with your logic. Haswell can't possibly be competing with trinity you argue, because haswell was initially designed 4 years ago, before trinity was released. Okay, I understand what you are saying- I may not fully agree, because I feel Intel could see what way AMD was planning to go as soon as AMD bought ATI, but whatever, you can make that argument.
But then you turn around and claim that Haswell was designed to react to tablets. Which, incidentally, did not exist as a viable market until the iPad created that market. Since the iPad was released AFTER Haswell's initial design 4 years ago (according to your logic above) somehow Intel reacted to the iPad a year before it was released?
