[CES 2013] quad-core SoC Qualcomm introduced Snapdragon 800 and 600, more powerful and power saving S4 Pro

Last year, Qualcomm introduced generation quad-core processor Snapdragon S4 Pro and it has been used in many high-end smartphones such as the LG Optimus G, Nexus 4, HTC Butterfly and recently Xperia Z. Today at CES 2013, the company continues to announce some new SoC with other naming ever.

First two Snapdragon chips are 600 and 800. We aim to phones, tablets and high-end smart TV is expected to appear in the next three to six months. Manufacturer said Snapdragon 800 samples can bring 75% higher performance than the S4 Pro by using production line 28nm High Performance for mobile (HPM), while S4 Pro is just the usual 28nm lines. Power consumption is thereby reduced. Qualcomm adds that SoC 800 uses four Krait CPU 400 (up to 2.3 GHz per core), Adreno 330 GPU, DSP Hexagon v5 and 4G transceivers LTE Cat 4 (150 Mbps) promises to enhance the performance of the whole system. Structures Symmetric multiprocessing (SMP) that Qualcomm Snapdragon 800 provides the ability to identify energy (dynamic power sensing) and control maximum performance per core CPU, while maintaining battery life without a special process (probably Qualcomm is trying to say to appear in Tegra 3/4). More about SMP, this is architecture in which two or more processor cores similar with a shared memory.

They will be controlled by a process in the operating system and each application, the software that enabled users to work in a separate press. Many app like that are allowed to run in parallel, thereby enhancing machine performance. Regarding the GPU Adreno 330, Qualcomm said it could bring computing power higher than 2 times compared to the Adreno 320. Snapdragon 800 will support both 32-bit LP-DDR3 running at 800MHz, allowing bandwidth to move data up to 12.8 GBps. A digital signal processor (DSP) Hexagon V5 provides floating-point computing power, multi-threaded run (dynamic multithreading) as well as expand the command instructions to help reduce energy consumption.

In addition we also have IZat technology combines multiple positioning systems with high accuracy. Another interesting point of Snapdragon 800 which is its integrated Wi-Fi 802.11ac, Wi-generation latest-Fi allows better speed and coverage than the 802.11n standard is widely used today. Up to this point, there was more ac Wi-Fi router launched from many different companies. Besides, Snapdragon 800 supports USB 3.0 connectivity, Bluetooth, FM, allows recording and playback photo resolution Ultra HD @ 30fps or 2560 x 2048 @ 60fps. These SoC devices can be used with highest screen resolution is 2560 x 2048, while the wireless video transmission through Miracast protocol is stopped in Full-HD 1080p.

Dual chip image signal processor for Qualcomm Snapdragon Camera supports better camera calculations. As for 7.1 surround sound, two technologies improve the quality of DTS-HD and Dolby Digital Plus will be Qualcomm into its chips. Meanwhile, Qualcomm Snapdragon 600 has a little more low profile, however it still provides 40% higher performance compared to the Snapdragon S4 Pro while consuming less power.

Qualcomm Snapdragon 800 and 600 are assigned to samples in which the SoC 800 is widely expected to appear in the middle of the year, and SoC 600 will appear in the second quarter of this year. Qualcomm representative revealed that there were more than 50 designs ready to integrate Qualcomm Snapdragon 600 as well as the 800. In addition, the upcoming Qualcomm will also give two lower-end processor of Snapdragon 400 and 200.
