Evolution of future high-end SoC "Snapdragon 810" and future prospects Summary
Qualcomm's next high-end SoC "Snapdragon 810Is a conventional modelSnapdragon 805Based on the stories heard from Qualcomm officials about how they evolved fromAnandTechIt is summarized.
AnandTech | Understanding Qualcomm's Snapdragon 810: Performance Preview
The Snapdragon 810 is an octa core of Cortex A 57 (4 up to 1.958 GHz) 4 core + Cortex A 53 (up to 1.555 GHz) 4 core, which combines two large and small processors to achieve high performance and power savingBig.LITTLEAdopted the configuration. It greatly evolves from Krait 450 (2.65 GHz 4 core) of the conventional high-end model Snapdragon 805.
In addition, the GPU will be changed from Adreno 420 to Adreno 430 and graphic performance is expected to rise by 30%. Snapdragon 810 is equipped with an HEVC encoder and supports 4 fps movies at 30 fps. In addition, the Image Signal Processor (ISP) improves from 1 GP / s Adreno 420 to 1.2 GP / s, so expectations for higher image quality of cameras will increase. Qualcomm said "Adreno 430 is not on the extension line of Adreno 420", suggesting a change in architecture, but avoiding the details as to details.
In addition, the internal memory has bandwidth of up to 24.9 GB / s by 32 bit dual channel LPDDR 4 - 1555, maintaining the same parity as Snapdragon 805 while decreasing bandwidth. In addition, LPDDR4 achieves 20% reduction in power savings with conventional LPDDR 3 ratio.
Snapdragon 810 supports carrier agreement (CA) which speeds communication by bundling different frequency bands. There is already a demonstration to stream 4K movies by CA of Snapdragon 810 at CES 2015 venue.
It is Snapdragon 810 which realizes higher performance with more power saving, but it is honestly that the future is uncertain. Snapdragon 810 has an unexpected fever problem and rumors are being whispered that there will be a delay in release timing. In relation to that, Samsung, a large customer at Qualcomm, is increasing the possibility of canceling the adoption of Snapdragon 810 in the next high-end smartphone Galaxy S 6 series and installing our own Exynos 7420.
Manufacturers that have announced the adoption of Snapdragon 810 already have Xiaomi (Small America), Oppo's Chinese forces in addition to Sony Mobile, LG, Microsoft, and expectations are expected for mass adoption to a growing Chinese smartphone, Based on China's antitrust violation, QualcommYou can order a reduction of 995 million dollars (about 116 billion yen) + patent fee for communicationWe also suffer from unexpected troubles in the Chinese market. Qualcomm's Snapdragon 810 led the high-end smartphone market while rival manufacturers for SoC manufacturing for mobile terminals such as MediaTek steadily improving the difference in performance and NVIDIA with Tegra X 1 with outstanding high performance are also evolving their products It seems that it can be said that it is unpredictable whether we can hold the right.
