Atom was originally developed not to deal with ARM but to usher in a new type of ultra mobile device. That obviously didn't happen. UMPCs failed, netbooks were a temporary distraction (albeit profitable for Intel) and a new generation of smartphones and tablets became the new face of mobile computing. While Atom will continue to play in the ultra mobile space, Haswell marks the beginning of something new. Rather than send its second string player into battle, Intel is starting to prep its star for ultra mobile work.
Haswell is so much more than just another new microprocessor architecture from Intel. For years Intel has enjoyed a wonderful position in the market. With its long term viability threatened, Haswell is the first step of a long term solution to the ARM problem. While Atom was the first “fast-enough” x86 micro-architecture from Intel, Haswell takes a different approach to the problem. Rather than working from the bottom up, Haswell is Intel's attempt to take its best micro-architecture and drive power as low as possible.
Read on for our full analysis of both Haswell as a microprocessor architecture and as a ultra mobile platform.
