MOBILE CHIP DESIGNER Qualcomm has unveiled its next generation 64-bit flagship processors for high-end smartphones and tablets, the Snapdragon 810 and 808, which the firm claims are its "highest performing" to date.

The Qualcomm Snapdragon 810 and 808 processors are aimed at improving the "connected mobile computing experiences in video, imaging and graphics" by integrating the firm's fourth generation Cat 6 LTE advanced multimode modem along with support for its RF360 front end and 3x20MHz carrier aggregation, which is said to enable speeds of up to 300Mbps.

"Both processors are designed in 20nm technology node with Cat 6 LTE, advanced multimedia features and 64-bit capability, all tightly integrated and optimised for low power consumption that does not sacrifice performance, making them the first premium-tier 64-bit processors to enable LTE Advanced globally with a single design," Qualcomm said.

The Snapdragon 810 processor is what Qualcomm is calling its "highest performing Snapdragon platform to date". Onboard there's the combination of 64-bit quad-core ARM Cortex A57 and ARM Cortex A53 CPUs, while implementation of the new ARMv8-A ISA enables improved instruction set efficiency.

Featuring LPDDR4 memory, the Snapdragon 810 also supports the native 4K Ultra HD video interface, along with an upgraded camera suite using gyro-stabilisation and 3D noise reduction for producing 4K video at 30 frames per second and HD 1080p video at 120 frames per second.

There's also an Adreno 430 graphics processing unit (GPU) built in that is designed for 4K displays and provides support for OpenGL ES 3.1 plus hardware tessellation, geometry shaders and programmable blending.

"The Adreno 430 is designed to deliver up to 30 percent faster graphics performance and 100 percent faster GPGPU compute performance, while reducing power consumption by up to 20 percent, as compared to its predecessor, the Adreno 420 GPU," Qualcomm said.

The firm also noted that the combined 14bit dual Image Signal Processors (ISPs) are capable of supporting 1.2GPps throughput and image sensors up to 55MP.

"Advanced imaging software helps enable advanced mobile camera features, including enhanced exposure, white balance and fast low light focus," Qualcomm said, adding that the Snapdragon 810 is also the first mobile processor to implement the firm's Vive two-stream 802.11ac with multi-user MIMO (MU-MIMO).

The Qualcomm Snapdragon 808 processor is also designed for high specification phones and integrates the same LTE advanced, RF360 and WiFi connectivity as the Snapdragon 810 processor but with 2K display support.

Other differences of the Snapdragon 808 processor are that it's designed for WQXGA 2560x1600 resolution displays, it features the Adreno 418 GPU offering up to 20 percent faster graphics performance than the Adreno 330 GPU, and it is configured with two ARM Cortex A57 CPU cores and a quad-core ARM Cortex A53 CPU.

The Snapdragon 810 and 808 processors are expected begin sampling in the second half of 2014 and should be available in devices by the first half of 2015. µ
