Samsung "actively working" on 64-bit processors, could launch the first one this year
Nevertheless, the first 64-bit processor made by Samsung will likely be introduced this year, according to CNET. Kyushik Hong, VP of marketing for Samsung's system LSI business, told CNET that "64-bit is very important - in the sense that there's a real demand, whether you need it or not." The exec concluded that Samsung is “very actively working on” developing its first 64-bit processor (we're guessing that this will be included in the Exynos family).
Although Qualcomm, Intel, Nvidia, Marvell, and even MediaTek have already announced 64-bit processors, Samsung is not worried. Its 64-bit chip “will be ready whenever the operating systems and ecosystem go 64-bit,” reportedly declared Kyushik Hong. In other words, Samsung is still waiting for Google to optimize Android for full 64-bit support.
Last year, Apple introduced its own 64-bit ARMv8 processor, the A7, which powers the iPhone 5S, the iPad Air and the iPad Mini 2 - these are the world's first commercially available mobile devices that come with 64-bit processors.
