Qualcomm 's SoC "Snapdragon 845" will be the heart of the next generation high - end smartphones, announced, 25% faster than previous models & 30% faster graphics processing

Next generation high-end SoC from Qualcomm "Snapdragon 845"Was announced. This is Samsung'sGalaxy S8Or Google'sPixel 2Mobile SoC mounted on high-end smartphones such as "Snapdragon 835"Although it is an 8-core SoC manufactured with the same 10 nm process, the processing speed has been increased by 25%, and furthermore, in the case of graphic processing alone, it is 30% faster.

In the "Snapdragon Technology Summit" held by Qualcomm in Hawaii, we announced Snapdragon 845, which will become the main SoC in 2018. Because Qualcomm offers nearly exclusive SoCs to high-end smartphones other than the iPhone and Galaxy, it is assumed that this Snapdragon 845 will be installed at the heart of high-end smart phones other than the iPhone / Galaxy that will appear in 2018 I will. Also, in 2018PC with ARM version Windows 10It is expected that Snapdragon 845-equipped terminals will appear from among these as well.

The Snapdragon 845 is an SoC manufactured in 10 nm process as well as the previous model Snapdragon 835. CPU core is equipped with eight "Kryo 385", the clock frequency is 2.8GHz, the remaining four Cortex A55-based efficiency in its inner four are CPU that is specialized for Cortex A75-based performance (Performance Core) The CPU frequency is important and the clock frequency is 1.8 GHz. The performance core's clock frequency has improved by 19% compared with the previous model, and Qualcomm wrote that the overall performance has improved by 25% due to CPU redesign. In addition, the CPU also has a new 2 MB L3 cache and 3 MB of system cache.


The GPU is equipped with "Adreno 630", resulting in 30% improvement in graphics processing and 30% improvement in power efficiency. By increasing the display throughput by 2.5 times, it is also possible to use a 2K × 2K display at a refresh rate of 120 Hz. By using this high-performance Adreno 630 GPU, you can use Snapdragon 845 for better eye tracking and hand tracking. For example, "Foviet Rendering" to recognize the line of sight of the player and render only around it, and "Multi View Rendering" to output images separately to the left and right eyes, HTC Vive style6 DoFIt will be possible to correspond to headsets and controllers. About this, Ars Technica of foreign media wrote that "Qualcomm is promoting AR and VR with Snapdragon 845". Also, for the first time in many functions, Qualcomm calls Adreno 630 "Visual Processing Subsystem" instead of GPU. Not all of the processing we mentioned here could be realized with GPUs so far, but from Adreno 630 Qualcomm has officially supported various VR and AR use cases.


In addition, Snapdragon 845 's ISP (Image Signal Processor) "Spectra 280" enables 4K · 60 fpsHDRIt is also possible to shoot movies at 10 bit color depth and shoot 720p slow motion movies at 480 fps. In addition, the picture can be recorded as a large capacity image of 60 frames / 16 million pixels per second, and it can be instantly applied to depth sensing etc.


In addition, Snapdragon 845 is equipped with SPU (Secure Processing Unit) completely isolated from others, which can be used for applications that need to pay attention to security such as virtual currency, settlement service, biometric authentication function It will be possible to process safely.


The cellular modem has an X20 LTE modem that can theoretically realize a download speed of up to 1200 Mbps. Wi-Fi supports the 802.11ad standard of 60 GHz, which does not replace the existing 802.11ac, it is a standard capable of ultra high-speed communication over a very short distance. Since the radio waves used in 802.11ad are weak against obstructions, it is not suitable for use in a wide range, but the maximum speed is 4.6 Gbps, and it is possible to transmit large capacity data from the terminal to the terminal by radio communication It may be the best way to receive and receive.


And Snapdragon 845 also focuses on artificial intelligence (AI), using "Hexagon 685 DSP" as AI and image coprocessor. The Hexagon 685 DSP is three times faster than the Hexagon 682 that was on the previous model Snapdragon 835, and is scheduled to be released on Android 8.1Neural network APIIt is also a feature that supports. It may be possible to improve "always-on keyword detection function and voice processing with ultra low power", so it may be a nice update for users who frequently use the voice assistant Google Assistant.


In addition, Snapdragon 845 is scheduled to ship in early 2018.
