Last week, Qualcomm announced two new processors aimed at premium tier 64-bit mobile computing devices – the Snapdragon 810 and 808, based on a combination of ARM® Cortex®-A53 and Cortex-A57 processors. The Cortex-A53 processor has been used by Qualcomm in all of its 64-bit product announcements so far (Snapdragon 410, 610 and 615), each with varying number of cores and operating frequency, and the Snapdragon 808 and 810 is the first time that we have seen Qualcomm use the Cortex-A57 processor as well.
Snapdragon 808 contains a dual-core Cortex-A57 processor and a quad-core Cortex-A53 processor, for a total of six heterogeneous cores, while the Snapdragon 810 delivers eight processor cores in a quad-core Cortex-A57 and quad-core Cortex-A53 processor combination.
The ARM Cortex-A57 and Cortex-A53 processors are both based on the new ARMv8-A architecture. The ARMv8-A architecture supports both 32-bit and 64-bit code, which enables the executing of both 32-bit and 64-bit applications on a 64-bit kernel, including application compiled for previous versions of the ARM architecture. This makes it possible to migrate in a step-by-step manner to ARMv8-A and its 64-bit capabilities.
The Cortex-A57 processor is ARM's most advanced, high-performance application processor. The Cortex-A53 processor delivers significantly more performance than its predecessors at a higher level of power efficiency, effectively taking the performance of the LITTLE core above that of the Cortex-A7 processor, which defines many popular high-end and mainstream mobile platforms. Together they offer significant power efficiency and performance advantage in various Android™ benchmarks:
As the first partner to use A57 and A53 together in their mobile A50 series parts, Qualcomm is one of the ARM partners leading the wide up take of ARM v8-A technology across the mobile computing market. Want to know more about how ARM big.LITTLE technology works? I shall leave you with this video.
