Envisioning mobile devices as becoming more computer-like than phone-like as they are used more for the delivery of high bandwidth multimedia, Qualcomm Technologies has introduced its newest 64-bit 810 and 808 Snapdragon mobile processors  designed to make its delivery over nextgen highbandwidth LTE communications networks even faster.

According to Murthy Renduchintala, executive vice president, Qualcomm Technologies, Inc., and co-president, QCT., both the Snapdragon 810 and Snapdragon 808 processors integrate the company's fourth generationn Cat 6 LTE Advanced multimode modem together with support for its RF360 Front End Solution, as well ast 3x20MHz Carrier Aggregation, which allows one device to combine more than one cell-network radio link into a single broadband network connection.

He said this will make possible speeds of up to 300 Mbps in the broadest set of spectrum deployment configurations to date. Both processors are designed in 20nm technology node with Cat 6 LTE, advanced multimedia features and 64-bit capability,

The new devices are one step up from the company's previous Gobi LTE modem with the ability to combine two LTE network connections using a 10 MHz-wide band of LTE wireless network spectrum into a single pipe with a theoretical download capacity of 150 Mbit/s.. By comparison, both the 808 and 810 have been design to combine three carrier links of 20 MHz each, which would top out at a theoretical combined top download speed of 300 Mbit/s,

Both chips incorporate multi-user MIMO dual-stream 802.11 a/c wireless network interfaces designed to send and receive data unidirectionally on different streams which improves delivery of multimedia over LTE by doing away with the need for a single receiver to stop talking in order to listen.

They incorporate as well, a rich native 4K Ultra HD interface, along with an upgraded camera suite using gyro-stabilization and 3D noise reduction for producing high quality 4K video at 30 frames per second and 1080p video at 120 frames per second.

On-chip 14-bit dual Image Signal Processors (ISPs) are designed to deliver 1.2GP/s throughput and image sensors up to 55MP., which will be useful in such advanced mobile camera features asincluding enhanced exposure, white balance and fast low light focus.

The capabilities of combined 64-bit quad core ARM Cortex-A57 CPUs and Cortex-A53 CPUs have been enhanced through the use of the ARMv8-A instruction set architecture as well as an onboard Adreno 430 graphics processing unit (GPU) for OpenGL ES 3.1 plus hardware tessellation, geometry shaders and programmable blending.

He said the combination results in up to 30% faster graphics performance and 100% faster GPGPU compute performance, while reducing power consumption by up to 20%, as compared to its predecessor GPU..

He said the Snapdragon 810 and 808 processors are expected to be available in sample quantities in the second half of 2014 and to be available in commercial devices by the first half of 2015. Developers can find tools to optimize their apps for Snapdragon processors at developer.qualcomm.com.
