In the warm-up on March 27th, Xiaomi said that Xiaomi Mi 11 Ultra will be the world’s first full phase change heat dissipation technology. [Picture] [Picture] What kind of technology is this technology? Or what changes can it bring?
The Mi 11 Ultra has a large pile of heat dissipation, which seems to be very powerful, but this is a product of compromise. The mobile phone actually has two directions. One is to make the processor energy consumption very high compared to what it does, and the heat generation is extremely low, so there is no need for heat dissipation. The second is that the energy consumption ratio of the processor is not high, the heat generation is high, and the stack heat dissipation is required. Everyone should understand these two directions, which one is right. Not much to say, let’s compare the energy consumption ratio of Apple A14 Bionic and Qualcomm Snapdragon 888. CPU core (Spec6): Apple A14 Bionic, 63.34 points/4.42W=14.33 points/W; Qualcomm Snapdragon 888, 41.3 points/3.16W=13.06 points/W. CPU mid-core (Spec6): Apple A14 Bionic, 20.03 points/0.44W=45.52 points/W; Qualcomm Snapdragon 888, 30.32 points/1.74W=17.42 points/W. GPU (GFX3.1): Apple A14 Bionic, 138 frames/5.6W=24.64 frames/W; Qualcomm Snapdragon 888, 120 frames/8.34W=14.38 frames/W. From the above data, we can see that the energy consumption ratio of Qualcomm Snapdragon 888 is much lower than that of Apple A14 Bionics, and its energy consumption is far behind Apple A14 Bionics than Qualcomm Snapdragon 888. This is why Apple dared not do any heat dissipation at all, and the Mi 11 Ultra needs to dissipate heat on such a large scale. Even if the heat dissipation is up, the performance release is similar to that of the Apple A14 Bionic model, but the power consumption of the Qualcomm Snapdragon 888 cannot be compared with the Apple A14 Bionic. The end result is that the Xiaomi Mi 11 Ultra is a half-catty phone, and its performance is similar to that of an extremely thin and light 133g mobile phone like the iPhone 12 mini. This is a compromise. So when we choose the Mi 11 series, the standard version is sufficient. The improvement of Mi 11 Ultra is traded in volume. For mobile phones that pay attention to portability, it is not worth sacrificing volume for improvement.
