Because Apple controls iOS, with their new 64-bit A7 processor, “they can ‘tune’ or ‘optimize’ the software to maximize efficiently every bit of the core they designed,” Ben Bajarin writes for TechPinions. “Apple needs only to design the A7 for one purpose – iOS. Therefore, they can focus in on optimization for performance gains in all areas they feel are important.”
“By moving to 64-bit and staying dual-core, Apple has effectively delivered equal to and perhaps better performance than competitors running quad-core chipsets with a dual-core solution,” Bajarin writes. “So where will this matter? Battery life is the biggest beneficiary in the short term. Every task that utilizes the CPU or the GPU will happen faster allowing the CPU to return to a low-power state much faster… By going to 64-bit now it sets Apple up for greater performance gains utilizing the architecture for their future. This years gains are 2X with better power efficiency. Next years will be 2X or greater with even better power efficiency and so forth. Each generation delivering better performance-per-watt.”
Bajarin writes, “Apple certainly could have kept riding the 32-bit curve and just added cores and optimization with each new process node. But by going 64-bit now, it means they have more grand ambitions to push the envelope in what is possible computationally with their smartphones, tablets, and perhaps more much sooner than expected. The iPhone will benefit from this, as I pointed out, with battery gains and new classes of applications (particular those that are graphically or computationally complex) but the real winner with this move will be the iPad.”
