General characteristics VKworld A88
Chip:
MediaTek MT6572
Process technology:
28 nm
CPU:The central processing unit (CPU) is the unit, which performs most of the processing inside a smartphone. To control instructions and data flow to and from other parts of the smartphone.
ARM Cortex-A7
CPU bits:
32 bit
Instruction set:
ARMv7
Level 1 cache memory (L1):
32 KB + 32 KB
Level 2 cache memory (L2):
256 KB
CPU cores:The central processing unit (CPU) in your computer does the computational work running programs, basically. But one single-core CPU can only perform one task at a time, which is where multiple CPUs, hyper-threading, and multi-core CPUs come into play. A processor core is a processing unit which reads in instructions to perform specific actions. Instructions are chained together so that, when run in real time, they make up your computer experience. Literally everything you do on your computer has to be processed by your processor. Whenever you open a folder, that requires your processor. When you type into a word document, that also requires your processor. Things like drawing the desktop environment, the windows, and game graphics are the job of your graphics card which contains hundreds of processors to quickly work on data simultaneously but to some extent they still require your processor as well.

CPU frequency:The clock rate typically refers to the frequency at which a chip like a central processing unit (CPU), one core of a multi-core processor, is running and is used as an indicator of the processors speed. It is measured in clock cycles per second or its equivalent, the SI unit hertz (Hz). The clock rate of the first generation of computers was measured in hertz or kilohertz (kHz), but in the 21st century the speed of modern CPUs is commonly advertised in gigahertz (GHz). This metric is most useful when comparing processors within the same family, holding constant other features that may impact performance. Video card and CPU manufacturers commonly select their highest performing units from a manufacturing batch and set their maximum clock rate higher, fetching a higher price.
1300 MHz
GPU:The GPU (Graphics Processing Unit) is a specialized circuit designed to accelerate the image output in a frame buffer intended for output to a display.
ARM Mali-400 MP1
GPU cores:
1
GPU frequency:
500 MHz
RAM capacity:RAM (random access memory) is the place in a computing device where the operating system (OS), application programs and data in current use are kept so they can be quickly reached by the devices processor. RAM is much faster to read from and write to than other kinds of storage in a computer, such as a hard disk drive (HDD), solid-state drive (SSD) or optical drive. Data remains in RAM as long as the computer is running. When the computer is turned off, RAM loses its data. When the computer is turned on again, the OS and other files are once again loaded into RAM, usually from an HDD or SSD.
512 MB
RAM type:
LPDDR2
RAM frequency:
266 MHz
Operating system (OS):A smartphone operating system is essentially the engine that smoothly runs your smartphone; it manages both the hardware and the software to create an enjoyable user experience. Examples of smartphone operating systems include Android, BlackBerry and Windows.
Android 4.2.2 Jelly Bean
SIM card type:The nanoSIM is the SIM cards fourth size standard since its inception. Designated as 4FF, or fourth form factor, it measures 12.3mm x 8.8mm x 0.67mm, a reduction of over 42 times from the SIMs inception. Most people, however, are more familiar with the 2FF SIM card, known more readily as the Regular SIM card. At 25mm x 15mm x 0.76, it is 3.4 times larger than today is current SIM cards, which offer the same features in a much more compact package. Some manufacturers still choose to use the microSIM format which, at 15mm x 12mm, is only slightly larger than the nanoSIM.
Mini-SIM (2FF - second form factor, since late 1990s, 25.00 x 15.00 x 0.76 mm)
Micro-SIM (3FF - third form factor, since 2003, 15.00 x 12.00 x 0.76 mm)
Number of SIM cards:
2
Features:
Dual SIM stand-by (Both cards are active. When one is busy, the other is not active)
Display VKworld A88
Type/technology:
IPS
Diagonal size:The size of a screen is usually described by the length of its diagonal, which is the distance between opposite corners, usually in inches. It is also sometimes called the physical image size to distinguish it from the "logical image size," which describes a screens display resolution and is measured in pixels.
4.7 in
Width:
2.3 in
Height:
4.1 in
Aspect ratio:
1.778
16:9
Resolution:Image resolution can be measured in various ways. Basically, resolution quantifies how close lines can be to each other and still be visibly resolved. Resolution units can be tied to physical sizes (e.g. lines per mm, lines per inch), to the overall size of a picture (lines per picture height, also known simply as lines, TV lines, or TVL), or to angular subtenant. Line pairs are often used instead of lines; a line pair comprises a dark line and an adjacent light line.
540 x 960 pixels
Pixel density:Pixels per inch (PPI) or pixels per centimeter (PPCM) is a measurement of the pixel density (resolution) of an electronic image device, such as a computer monitor or television display, or image digitizing device such as a camera or image scanner. Horizontal and vertical density are usually the same, as most devices have square pixels, but differ on devices that have non-square pixels.

Video FPS:In motion pictures, television, and in computer video displays, the frame rate is the number of frames or images that are projected or displayed per second. Frame rates are used in synchronizing audio and pictures, whether film, television, or video. In motion pictures and television, the frame rates are standardized by the Society of Motion Picture and Television Editors (SMPTE). SMPTE Time Code frame rates of 24, 25 and 30 frames per second are common, each having uses in different portions of the industry. The professional frame rate for motion pictures is 24 frames per second and, for television, 30 frames per second (in the U.S.).

GPSThe Global Positioning System (GPS) is a satellite-based navigation system made up of a network of 24 satellites placed into orbit by the U.S. Department of Defense. GPS was originally intended for military applications, but in the 1980s, the government made the system available for civilian use. GPS works in any weather conditions, anywhere in the world, 24 hours a day. There are no subscription fees or setup charges to use GPS.

Wi-Fi:Wi-Fi is the name of a popular wireless networking technology that uses radio waves to provide wireless high-speed Internet and network connections. A common misconception is that the term Wi-Fi is short for "wireless fidelity," however this is not the case. Wi-Fi is simply a trademarked phrase that means IEEE 802.11x.
802.11b (IEEE 802.11b-1999)
802.11g (IEEE 802.11g-2003)
802.11n (IEEE 802.11n-2009)
Wi-Fi Hotspot
Bluetooth:Bluetooth is a wireless technology for exchanging data over short distances. The chip can be plugged into computers, digital cameras and mobile phones.

Features:
A2DP (Advanced Audio Distribution Profile)The Advanced Audio Distribution Profile is a Bluetooth profile that allows for the wireless transmission of stereo audio from an A2DP source (typically a phone or computer) to an A2DP receiver (a set of Bluetooth headphones or stereo system). Such devices typically also support the AVRCP profile as well in order to allow for track selection and such. A common misconception is that A2DP support is available on all Bluetooth 2.0 devices, which is not the case, and that A2DP is only available on Bluetooth 2.0 devices, which is also not true. A2DP support can exist in older versions of Bluetooth, it just was not commonly supported.
