Intel, Mediatek and Allwinner have all come out with new SoC announcements at Mobile World Congress and Qualcomm is no different. By far the most interesting release is what it calls the "first commercial" 64-bit Octa-Core chipset with integrated global LTE support. The list of features and technologies included on the chipset is impressive.
The Snapdragon 615 integrates 8 x ARM Cortex-A53 cores that opterate on the newer 64-bit ARMv8 architecture while supporting 32-bit for backwards compatibility. Qualcomm is not using a custom designed CPU core for this chipset but the company has stated it will have its own custom 64-bit core sometime in 2015. This 8-core model is divided into a pair of quad-core clusters that will be tuned to different clock speed and power levels, offering the ability to run slightly more efficiently than would be possible with all cores tuned to the highest performance.
Snapdragon 610 is essentially the same design but is limited to a quad-core, single cluster setup.
Both of these parts will integrate the Qualcomm custom built Adreno 405 GPU that brings a DX11 class feature set, along with OpenGL ES 3.0 and OpenCL 1.2. The Adreno 405 performance is still unknown but it should be able to compete with the likes of PowerVR's Series6 used in the Apple A7 and Intel Merrifield parts. Quad HD resolutions are supported up to 2560x1600 and Miracast integration enables wireless display. H.265 hardware decode acceleration also found its way into the 615/610.
Connectivity features of the Snapdragon 615/610 include 802.11ac wireless as well as the company's 3rd generation LTE modem. Category 4 and carrier aggregation are optional.
Qualcomm has publicly stated that the move to 8-core processors with software lacking the capability to manage them properly was a poor decision. But it would appear that the "core race" has infected just about everyone.
