PerformanceThe internal storage refers to the built-in storage space available in a device for system data, apps, and user-generated data. With a large amount of internal storage, you can save more files and apps on your device. Random-access memory (RAM) is a form of memory used to store working data and machine code. Having more RAM is particularly useful for multitasking, allowing you to run more programs at once or have more tabs open in your browser. The CPU speed indicates how many processing cycles per second can be executed by a CPU, considering all of its cores (processing units). It is calculated by adding the clock rates of each core or, in the case of multi-core processors employing different microarchitectures, of each group of cores. The device has a standard memory slot (such as an SD or micro SD card slot) that enables you to extend the built-in internal storage with affordable memory modules, or easily retrieve data, such as photographs, from the memory card. Small semiconductors provide better performance and reduced power consumption. Chipsets with a higher number of transistors, semiconductor components of electronic devices, offer more computational power. A small form factor allows more transistors to fit on a chip, therefore increasing its performance. A 32-bit operating system can only support up to 4GB of RAM. 64-bit allows more than 4GB, giving increased performance. It also allows you to run 64-bit apps. The maximum amount of external storage memory supported by the the device. The system on a chip (SoC) has an integrated LTE cellular chip. LTE is capable of downloading at faster speeds than older, 3G technology. Using big.LITTLE technology, a chip can switch between two sets of processor cores to maximize performance and battery life. For example, when playing a game the more powerful cores will be used to increase performance, whereas checking email will use the less powerful cores to maximize battery life. CamerasThe number of megapixels determines the resolution of the images captured with the main camera. A higher megapixel count means that the camera is capable of capturing more details. However, the megapixel count is not the only important element determining the quality of an image. The number of megapixels determines the resolution of the images captured with the front camera. A higher megapixel count means that the front camera is capable of capturing more details, an essential factor for taking high-resolution selfies. The maximum resolution available for videos shot with the main camera. Although it may be possible to choose among other frame rates, those recordings usually have lower resolutions. has a flash ✖Apple iPad Air 2 WiFi + Cellular ✖Samsung Galaxy Tab S2 9.7 A flash is good for low-light environments, and can sometimes be used as flashlight. A front camera, also called secondary camera, can be used for video chats/selfies. It can automatically shoot pictures with a higher dynamic range (HDR). It allows you to take multiple photos capturing different parts of the scene, and then joins them together into a single photo. Slow-motion is an artistic video effect that makes time seem to go slower. It is achieved by recording a video at a higher frame-rate than the standard playback rate of 24fps or 30fps. Depending on camera capabilities, frame rates for slow-motion videos vary between 60fps and 960fps. The autofocus is immediately set to the subject by just touching it on the touch screen.
