A processor is a component responsible for executing the arithmetic, logical, input, and output operations. Speed and performance of the smartphone will depend on the capability of the processor. Modern Processors comes with embedded GPU, memory, antennas, wifi and other connectivity modules. Hence they all come integrated into a single chip called System On Chip (SoC).
Head over to this page to know the Basics factors, Various brands, and ranges of Smartphone processors. Fundamental factors can be used while selecting the type and range of the processor. For choosing a Smartphone with the best processor, One should know about Cores, Clock rate, Architecture and Manufacturing Process of the Processor.
A core is the central processing unit, a processor having more than one core are called multi core processors. More no of cores favors the multi tasking, and More apps can be operated at once. But an application cannot utilize all the cores of a processor at the same time so the no of cores cannot solely determine the processor performance. Processor with more no of cores will be able to load more apps at once, but an app to load faster and efficient, we should also consider the type of cores like A72, A57, A53. Don’t believe in the myth, that Octa-core processor always performs better than a quad core processor.
Types of Cores:
A72 and A73 cores provide High single core performance with balanced battery use, A57 and A53 cores are medium performers comparatively with A72 cores. So processor with A72 cores would be simply better, regardless of no.of cores in a processor. These are the reasons why Snapdragon 820 with 4 A72 cores outperforms the SD 650 with 6 cores (Two A72 cores and four A53 cores), and in turn, SD650 outperforms SD 625( 8- A53 cores at 2.0 GHz) and SD430 (8 Cores at 1.4GHz) in the performance department.
The smartphone processors are fabricated using semiconductors, the thickness measured in Nano-meters. That what we listen 28 nm, 20 nm, 14 nm..etc. when reading the specs of the processor. Lower numbers play better here, as they produce less heat while running improving the battery life. For example, a 14 nm processor will be more efficient than 20 nm and 28 nm processors. A 14nm processor SD 625 provides better battery life up to 40% when compared to 28 nm process SD 650 processor. Similarly, SD 625 (14 nm) will be 20% high performer & 40% more power efficient than SD430 (28 nm)
The speed at which processor runs is the clock rate, measured in GHz. Clock rates are not the biggest factors and have very slight and negligible impact. Think, How extra speed can be useful for an engine without having the capability? So performance majorly depends on Type of cores and manufacturing process. Clock rates only have minimal effects on Performance.
Architecture is not an actor while choosing a processor, but an important thing to know about the processor. ARM is most widely used architecture by the all popular Chipset manufacturers in common, irrespective of the brand. Most preferably, just choose a processor with 64 bit ARM architecture, that’s it.
Exception: Few Flagship processors may ideally deviate to the Custom architecture, which is well optimized for better performance. That shouldn’t be a big problem, as Flagships deserve some custom things for their high cost. Example: Snapdragon 820 and 821 with Custom Kryo Cores.
So Ultimately, to choose a smartphone with the best processor, once should first look into No.of Cores, then proceed with the type of cores and Manufacturing process used. Users can compromise or ignore the Clock rate and Architecture, as their effect is minimal on performance. Follow our Tag Android Class for more useful and basics related to Android.
