Video, gaming and rendering applications demand processors execute relatively complex calculations. Graphics processors are better suited for these applications because they're able to execute many software instructions simultaneously. An integrated processor is a graphics processor which is pre-installed on the motherboard.
SidePort Memory Boost

While many graphics processors have their own on-board memory, graphics unit manufacturer AnandTech (ATI) refers to the memory on its cards as a "SidePort Memory Boost." According to ATI, graphics processors that have their own memory not only take up less of the computer's random access memory (RAM) but they minimize overall power consumption.

DDR3 is the third generation of double data rate (DDR) memory. This type of memory transfers data twice per memory access. DDR3 represents an improvement over DDR2 in that it transfers eight bits of data per access as opposed to four bits. "1333" is a speed rating indicating that the DDR3 makes 1.333 billion data transfers per second.
