While it is not a flagship solution, it is able to handle complex graphics in Full HD+ resolution, which is native to the screen of this smartphone.
The Hidden Power of AI Engine
In the console AIE There is a separate unit for artificial intelligence tasks, which unloads the main cores when recognizing scenes in the camera and processing speech.> The effectiveness of the Snapdragon 660 depends largely on how the operating system distributes processes among the eight available cores. Heterogeneous computing structure allows background applications such as instant messengers or email clients to run on energy efficient cores Cortex-A53. This minimizes power consumption in standby mode and under light load, which is critical for autonomy. When a user launches a heavy app or game, the system activates a cluster of four production cores. Cortex-A73. These cores are capable of performing complex mathematical calculations and quickly respond to user actions. However, long-term operation at maximum frequencies can lead to trotting, a forced frequency reduction to prevent overheating, which is the normal protective reaction of the processor. The memory controller in the Snapdragon 660 supports the LPDDR4X standard with a frequency of up to 1866 MHz. This provides the high bandwidth necessary for fast downloading applications and smooth switching between them. In conjunction with eMMC 5.1 or UFS 2.1 drives (depending on the modification), the processor demonstrates responsive interface. Performance in games and benchmarks, one of the high bandwidths, which Xiaomi has become popular for the 140 000 of such devices, the RedmiTu for the popularity of the mobile devices, the 140 000. This result is considered a great indicator for the middle class, although modern flagships have gone far ahead, scoring more than a million points. 512 shows the following results: 🎮 PUBG Mobile: The game starts on medium graphics settings with the option of choosing "HD" Frame rate stabilizes at the level of quality. 30-40 frames per second, however, with long sessions, performance may be reduced due to heating. 🏎️ Asphalt 9: Legends: Requires graphics settings to be kept to a minimum for comfortable play.The processor handles track rendering, but complex particle effects can cause micro-freezes. ⚔️ Mobile Legends / Arena of Valor: On medium and high settings, the game goes smoothly, providing stable and stable performance. 60 FPS, This makes the processor relevant to MOBA-discipline. It is worth noting that the heat sink in the case of the smartphone plays no less a role than the chip itself. In the Redmi Note 7, graphite film and a metal frame are used to dissipate heat, but with prolonged gaming in a closed case, trottling occurs faster. For serious gaming, it is recommended to remove the protective casing or use external cooling. The effect of the processor on the camera and multimedia The quality of photography depends on the capabilities of the camera. ISP (Image Signal Processor built into Qualcomm's platform.Snapdragon 660 uses dual-use ISP, It allows you to process data from two cameras at once, which allows you to implement a portrait mode with a blurred background (boke) and provides fast autofocus. The Redmi Note 7 features a 48-megapixel Samsung GM1 sensor that combines 4 pixels into one thanks to processor algorithms, giving a 12-megapixel final photo with improved detail and color rendering. In terms of video recording, the chip's capabilities are limited to 4K resolution support at 30 frames per second. However, due to Xiaomi's software policy, the standard camera app often only has Full HD at 60 FPS or 4K at 30 FPS with strong compression. Video stabilization is software-integrated, since optical stabilization (OIS) is not available in this model and the processor shakes the handle.
