Comparing Battery Consumption of Snapdragon Processors: 660, 660, and 845
When it comes to smartphone processors, the choice between a budget processor like the Snapdragon 660 or 636 and a flagship processor like the Snapdragon 845 can significantly impact a device's battery life. Let's delve into the factors that influence power consumption and efficiency in these processors, focusing on architecture, performance, and use cases.
Architecture and Technology
The architecture and manufacturing process are key determinants of a processor's power consumption. The Snapdragon 845 is built using a more advanced 10nm process technology, whereas the Snapdragon 660 and 636 are based on 14nm technology. A smaller node size generally translates to better power efficiency and better performance per watt, thanks to reduced transistor size and enhanced design optimizations.
Performance vs. Power Consumption
The nature of the tasks a processor can handle also affects its power consumption. The Snapdragon 845 is a high-performance flagship processor, optimized for intensive tasks such as gaming, multitasking, and demanding applications. This makes it a good choice for users who prioritize cutting-edge performance, even though it can consume more battery under heavy loads.
In contrast, the Snapdragon 660 and 636 are mid-range processors designed to strike a balance between performance and power efficiency. They are optimized for everyday use scenarios where sustained performance is important, but power consumption needs to be managed. This makes them more efficient for tasks that do not require peak performance.
Power Efficiency
In terms of raw power efficiency, budget processors like the Snapdragon 660 and 636 generally consume less power during light or moderate tasks. As they prioritize battery life, these processors have features and optimizations aimed at managing power consumption effectively. However, during demanding tasks, the Snapdragon 845 may become less efficient due to its focus on delivering high performance.
DVFS (Dynamic Voltage and Frequency Scaling) is a feature in the Snapdragon 845 that helps manage power consumption during lighter tasks. This ability to dynamically adjust voltage and frequency allows the processor to save power when it's not under heavy load.
Summary
The Snapdragon 845 can consume more battery under heavy usage compared to the Snapdragon 660 or 636, but it may be more efficient during lighter tasks due to its advanced architecture. Budget processors like the 660 and 636 are generally more power-efficient for everyday tasks, while flagship processors like the 845 excel in performance but may consume more power when fully utilized. Therefore, the choice between a flagship and a budget processor often depends on the intended use case and the balance between performance needs and battery life expectations.
Conclusion
Ultimately, the decision between a budget processor and a flagship processor depends on your usage scenario. If you are prioritizing battery life and balanced performance, budget processors like the Snapdragon 660 and 636 are a good choice. If you require top-tier performance for tasks like gaming, advanced multitasking, and more intensive applications, the Snapdragon 845 is the way to go, despite the trade-off in battery consumption.
