The ratio between the long and the short side of the display In mobile devices display size is represented by the length of its diagonal measured in inches. One of the main characteristics of the display is its type/technology, on which depends its performance. Data in the RAM is lost after the device is turned off or restarted.ĭisplay The display of a mobile device is characterized by its technology, resolution, pixel density, diagonal length, color depth, etc. RAM (Random-Access Memory) is used by the operating system and all installed applications. They handle the computation of graphics in various applications. Similar to the CPU, the GPU consists of processing units called cores. GPU can also perform computation in applications traditionally handled by the CPU. In mobile devices GPU is usually utilized by games, UI, video playback, etc. GPU is a graphical processing unit, which handles computation for 2D/3D graphics applications. It is measured in Megahertz (MHz) or Gigahertz (GHz). The frequency of the processor describes its clock rate in cycles per second. They increase the performance of the device allowing the execution of multiple instructions in parallel.
Presently, besides single-core processors, there are dual-core, quad-core, hexa-core and so on multi-core processors.

If the CPU does not find the data needed in L2, it proceeds to look for them in the 元 cache memory (if there is such) or in the RAM.Ī CPU core is the processor unit, which executes software instructions. Just like L1, it is much faster than the system memory (RAM). The L2 (level 2) cache memory is slower than L1, but has a larger capacity, instead, which allows it to cache more data. In some processors the search in L1 and L2 is simultaneous. If the processor does not find the data needed in L1, it continues to look for it in the L2 cache memory. The L1 (level 1) cache memory has a small volume, but operates faster than the RAM and the rest cache memory levels. The cache memory is used by the processor in order to shorten the time needed to access data and instructions that a frequently used. Information about the set of instructions the processor can execute. The instruction set architecture (ISA) is a set of commands used by the software to manage the CPU's work. 64-bit CPUs provide better performance than 32-bit ones, which on their part perform better than 16-bit processors. The CPU bits are determined by the bit-size of the processor registers, address buses and data buses. Its main function is to interpret and execute instructions contained in software applications. The value in nanometers represents half the distance between elements that make up the CPU.ĬPU is the Central Processing Unit or the processor of a mobile device. Information about the process technology used in manufacturing the chip. The SoC integrates different hardware components such as the CPU, GPU, memory, peripherals, interfaces, etc., as well as software for their functioning. This parameter has more weightage when compared to other departments.System on Chip (SoC) A system on a chip (SoC) includes into a single chip some of the main hardware components of the mobile device. This aspect is decided on various sub specifics, such as availability of microSD card slot, the amount of RAM the device offers, processor capability, and the network support. So, we compare a smartphone with the contemporaries to rate the value-for-money of a device out of 5. Value for MoneyĪ smartphone could have great specs, but if it is not priced well then you might not get the best value-for-money. And there are a lot of parameters like the panel technology (IPS LCD, OLED, TFT) and other parameters also taken into consideration like the resolution, pixel density, and refresh rate. Though battery seems like an underrated feature and we look at the battery capacity, fast charging supporting technology, and even the wireless charging capability is also taken into consideration to rate smartphone's battery capability. Any device that scores more than 3.5 can take good photos and videos and if a phone scores over 4, then it will be one of the best camera smartphones in the market. We consider various parameters like MP count, aperture size, pixel size, image stabilization to rate a camera system of a smartphone out of 5. CameraĬameras have evolved a lot over the last few years and multi-camera setup is a new norm. So, here are how these specs will affect the real-life usage of a device and why how we meticulously consider each of these points to rate a smartphone. Rating a smartphone is a tedious process and a lot of parameters have to be considered before judging the overall performance of the device such as display, camera, processor, RAM, storage, battery, and the pricing.
Yes, HSDPA, 7.2 Mbit/s, HSUPA, 5.76 Mbit/s
