Huawei Mate10 was just released, and was finally disassembled and analyzed at the chip level by foreign media techinsights. Some unknown details of Kirin 970 were exposed. Huawei is the only mobile phone manufacturer in the world besides Samsung that has mastered the core chip technology solution. The baseband, RF transceiver, power IC, audio chip, etc. of mobile phones are all independent mobile phones.
The chip size of Kirin 970 is 9.75mm x 9.92mm=96.72mm two , the overall area is larger than that of the previous generation (10.77mm x 10.93mm=117.72mm two ）It is also 18% smaller. Thanks to the 10nm process, the large core area of Kirin 970 has decreased by 38% and the small core area has decreased by 25%. The size of A73 core has changed from 1.37 mm two Reduced to 0.83 mm two , the effect is excellent. Even for the GPU with a soaring number of cores, the 12 core Mali-G72 core is 19% smaller than the previous generation of 6-core G71. Most unexpectedly, the area of NPU highlighted in the press conference was very small.
Other components include the new RF transceiver Hi6363, which is one of the secrets of Huawei's ability to achieve Cat 18/Cat 13 speed. There are three power management chips Hi6421, Hi6422 and Hi6423 in Mate10. The previous generation charging IC Hi6523 has been retained. In addition, Texas Instruments BQ25870 has been found on the motherboard.
The most interesting thing is that foreign media also compared the hardware costs of Mate 10, iPhone X, iPhone 8, and Galaxy S8. In addition to the low cost iPhone 8, Huawei Mate 10 costs only a little more than the iPhone 8. The cost of Huawei Mate 10 is 290 dollars, equivalent to about 1900 yuan, far lower than the iPhone X and Samsung's flagship Galaxy S8 half a year ago.
The screen cost of Mate10 is even lower than that of iPhone 8. Its particularly expensive components include memory, storage and camera, but the cost of RF transceiver, power management and other components is not different from that of other machines. Among them, the screens of iPhone X and Galaxy S8 are quite expensive, resulting in a large part of their costs.
