I dont think its this at all. What happened is the processors became fast enough. Each year the processors were "twice as fast" as the year before. Somewhere around the A10 there were diminishing returns, where being twice as fast wasnt useful anymore. Much like laptops, once they got fast enough, energy efficiency became the most important metric.
