Apple was the first to introduce a 64-bit mobile processor which was used in the Apple iPhone 5S. Then, Nvidia and Samsung introduced their next generation high-end 64-bit processors which are already being used in commercially available devices such as the Xiaomi MiPad 7.9 and the Samsung Galaxy Note 4. Qualcomm might be one of the last one to introduce a high-end 64-bit processor, the Snapdragon 810 in the market.
According to a Chinese tech analyst Pan Jiutang, Vivo Xplay 5 could be the first device to sport a Snapdragon 810 processor. It could also be used in the Oppo Find 9 and Xiaomi Mi 5 but the Vivo Xplay 5 has a higher chance with it being announced either in December 2014 or January 2015.
The Qualcomm Snapdragon 810 is an octa-core processor which uses four ARM Cortex A57 CPU cores along with four ARM Cortex A53 cores working in big.LITTLE manner. It also features a powerful Adreno 430 GPU and inbuilt 4G LTE radios. By the time it becomes available to OEMs later this year or early next year, Qualcomm will see it compete with dual-core Nvidia Tegra K1 with 64-bit Denver CPU, octa-core Samsung Exynos 5433 and octa-core MediaTek MT6795.
