    Apple was the first company to introduce the 64-bit architecture chipsets which debuted in iPhone 5s. The 64-bit CPU - Apple A7 was based on ARMv8 instructions. Now the news has it that Samsung is also said to be working on its 64-bit Exynos chipsets. The leading mobile chipset manufacturer - Qualcomm today announced its latest flagship grade 64-bit architecture CPU’s - Snapdragon 810 and 808. Earlier, Qualcomm had announced the 64-bit Snapdragon CPU’s – 410,610 and 615. Both the new Snapdragon 810 and 808 chipsets bring improvements in processor performance, 3D graphics, video, imaging and LTE. Also, both the chipsets use big.LITTLE architecture.


    Snapdragon 810

    This chipset replaces the Snapdragon 805 as the flagship CPU. It is an octa-core chipset which features four Cortex-A57 and four Cortex-A53 cores. It supports the new ARMv8-A instruction set for improved efficiency. The Snapdragon 810 uses Adreno 430 GPU which supports 4K displays and OpenGL ES 3.1. The Adreno 430 is said to deliver 30% faster graphics performance against the Adreno 420 GPU while reducing the power consumption by up to 20%.

    This chipset also has a hardware H265/HEVC encoder. The 810 uses dual 14-bit ISP (Image Signal Processor) which provides amazing imaging experience and supports image sensors up to 55MP.

    Snapdragon 808

    This one is a hexa-core chipset with a combination of two Cortex-A57 cores and four Cortex A-53 cores. The Snapdragon 808 uses Adreno 418 GPU, which comes under Adreno 420 found in Snapdragon 805 and has 20% better performance than Adreno 330. The chipset has an 12-bit dual ISP that can decode H265/HEVC but not encode it.


    Both the new chipsets feature 4G LTE Cat.6 modems which offer maximum download speeds of 300MBps and use 20nm manufacturing process which helps in 20% less power consumption than the 28nm chipsets. The Snapdragon 810 and 808 will be available in first half of 2015.

      Finally a range of processor that not just lay stress on performance but also on power savings.

      ARM's big.LITTLE technology is one of the prime reason behind less power consumption & better peak performance.Even though company claims it to be octa-cores, it really ain't because out of two clusters (one with big cores & other with small cores) only one cluster is activated at a time, while other cluster is not receiving any power. (Which is done using big.LITTLE code )

      In Snapdragon 810 there is one cluster of four A57 cores (BIG cores) & another cluster of four A53 cores (small cores). The switching of cores from A57 to A53 & vice versa happens as per the workload and thus results in better performance plus more power saving.
      However, Snapdragon 808 is hexacore with one cluster of two BIG cores & another cluster with four small cores hence performance wise it's inferior to Snapdragon 810.

      Handset sellers are fooling non-technical buyers in the name of octa-core.
