Usage of Single Core processors :
Single Core Processors are typically suitable for Browsing, running E-mail clients, Messengers, Audio Players etc. Unlike the mass thinks, for most of the commonly used programs, using a Single Core processor of higher clock speed is effective – they are optimized for running these apps, they cost less and consumes less electricity directly and indirectly through cooling.
Usage of Multi Core Processors
Multi Core processors can be of Dual Core, Triple Core, Quad Core or Hexa Core. Multi Core processors are good choice for 3D rendering applications like 3DS Max, Maya ; Professional audio editing softwares like Sony Sound Forge, Video Editing and the commonest software Adobe Photoshop. These are the common usage of Multi Core Processors.
More about Multi Core Processors
Multi Core Processors are not like single core. Within the operating system Multi Core Processors is treated as multiple units. Depending on the number of cores of Multi Core Processors, it is labeled to indicate that how many cores are integrated in the processor :
This is a typical instance of Multi Core Processor – note the distribution of work within the cores.
Multi Core Processors interconnects multiple cores in a processor. This means that the modern processors have not only a unit, but several subs that at some point can run application or process independently. These calculations include the distribution of Multi Core Processors. It’s called the automatic parallelization of Multi Core Processors. In 3D rendering software, the parallel computing technique is used vastly and used properly by these Multi Core Processors.
Multi Core Processors architecture rely on the fact that the processor cores share the cache and the physical memory. More cores a processor has, the more memory and more bandwidth is required. The access memory and interfaces will remain within limit when multiple cores have to share the bus to the chipset.
