I would normally agree, but the iPhone 5 already has a 64x chip...made by samsung funny enough. Samsung was supposed to be working on their version this year.
Samsung’s 64-bit chipsets will launch later this year
While almost all hardware manufacturers are getting on the 64-bit bandwagon, Samsung has not announced uncharacteristically silent in this segment. That does not mean that the South Korean giant isn’t working on any 64-bit hardware. The vice president of marketing for Samsung’s system LSI business, Kyushik Hong, announced in an interview at the Mobile World Congress that work is underway on 64-bit chipsets, which will be launched later this year. He said that there isn’t an ecosystem for 64-bit hardware yet, and when there is, Samsung will be ready with new hardware. “64-bit is very important … in the sense that there’s a real demand, whether you need it or not. We are very actively working on it.”
He also confirmed that there wouldn’t be a delay in launching the hardware once there is an ecosystem for it. “Our chip will be ready whenever the operating systems and ecosystem go 64-bit. We’re pretty sure we’re not going to be the bottleneck for that.”
The South Korean manufacturer has high ambitions for the Exynos line of SoCs and has signified its intentions of increasing its market share in the segment. Toward that regard, Hong said that Samsung’s LSI division is actively working on adding new vendors that use Exynos hardware. He did mention that it is initially hard to convince potential customers in the benefits of Samsung hardware, considering that most of these customers are Samsung’s rivals in the mobile or tablet segments. But he did state that there is a clear demarcation between Samsung’s mobile division and its LSI division, and that, “Once we work with our customers, then they fully appreciate this separation between the different business units.” In addition, Hong mentioned that work is underway on creating new products for the mid- and low-tier segments.
