In the early morning of November 11, Qualcomm officially released the latest generation of mobile flagship chip - Snapdragon 820. After experiencing the tragic failure of Firedragon 810, Qualcomm must increase publicity on PPT this time, and become more and more brave. Once we understand the worries of manufacturers, let's see how powerful the Snapdragon 820 is!

Snapdragon 820 (MSM8996) uses its own Kryo architecture and 64 bit processor this time, which is the first 64 bit SoC of Qualcomm using its own architecture. In terms of CPU, Snapdragon 820 uses four Kryo cores, Two large cores (2.2GHz)+two small cores (1.6~1.7GHz), using Samsung 14nm FF LPP technology, support 1866MHz LP DDR4 memory, and can provide 29.8GB/S bandwidth. The PPT also said that the Snapdragon 820 has doubled its performance and energy consumption compared with the previous generation. For GPU, use the latest Adreno 530, which supports OpenGL ES 3.1+AEP，OpenCL2.0， 64 bit virtual addressing DirectX 11.2, surface subdivision. PPT also said that compared with the previous generation Adreno 430, it has increased by 40%, and the energy consumption ratio has increased by 40%. In terms of flash memory, UFS 2.0 and eMMC 5.1 flash memory are supported.

In terms of photography, video, audio and screen, Snapdragon 820 supports 14 bit dual ISPs, and uses Hexagon ™ 680 DSP performs digital signal processing, and its performance is improved by two times, and its energy consumption ratio is increased by 10 times, Support 25 million pixels, 30 pictures/S continuous shooting, and reduce the power consumption by 25% compared with the previous generation ， Video decoding supports 10 bit 4K 60fps, 1080P 240fps HEVC(H.265) 10-bit/VP9 , better and reasonable screen power consumption control, reduce 25% power consumption of LCD/AMOLED screen compared with the previous generation, support higher screen refresh rate, support REC.2020 color gamut, provide professional color calibration, color management, increase screen details Audio encoder WCD9335, capable of playing Hi Fi 24bit, 192kHz FLAC , which can reduce the delay of 3D stereo, provide HIFI surround sound, reduce flux noise, and enhance game sound effects and virtual audio.

In terms of calls and networks, it supports X12 LTE, covering LTE FDD, LTE TDD, WCDMA (DB-DC-HSDPA/DC-HSUPA), TD-SCDMA, CDMA 1x/EVDO, GSM/EDGE networks, and supports LTE Cat.12， It can reach the maximum download speed of 600Mbps (75MB/S), and the upload speed of 150Mbps (18.75MB/S). The download speed is 33% faster than Snapdragon 810, and the upload speed is 200% faster than Snapdragon 810. The 11ac MU-MIMO Wi Fi module supports 2.4GHz, 5GHz and 60GHz WIFI. The power consumption of mobile phones as WIFI hotspots is reduced by 45%. Reduce the drop rate of 30% during the call, and reduce the call power consumption.

In terms of fast charging, it supports the latest Qualcomm 3.0 fast charging scheme, It only takes 35 minutes to charge from 0% to 80% , its charging power is 4 times that of traditional charging, its charging speed is 2 times higher than Qualcomm Fast Charge 1.0, and its speed is 38% higher than Qualcomm Fast Charge 2.0, Its charging voltage can be adjusted between 3.6V and 20V, At the same time, Qualcomm Fast Charge 3.0 is downward compatible with Fast Charge 1.0 and 2.0 solutions, supporting USB Type-A、USB-Micro、 as well as USB Type-C interface, Intelligent battery management is also added to reduce battery consumption by 20%

At the press conference, Tim McDom, vice president of marketing of Qualcomm, has repeatedly stressed that Snapdragon 820 is a mobile chip that can create immersive experience, which can bring unparalleled experience in vision, hearing and communication. At the same time, in response to questions from the media, he also said that Snapdragon 820 uses the most advanced 14nm process, and there is absolutely no heating problem.

In fact, this PPT, everyone will say, just follow the instructions. We have experienced many battles in the field of aviation. What kind of PPT have we not seen? Nvidia's PPT is much higher than you don't know. I feel that you Qualcomm still need to improve your own technical level. Don't pay too much attention to PPT. Whether the Snapdragon 820 is hot or not, run NBA 2K15 and we will know!
