Quad core computer contains four processors and can be considered a part of the family multicore processors. There is little doubt that the performance of quad-core computer is much faster than the dual-core computers. However, the performance of quad core computer depends on the type of programs that are run and the algorithms used in these programs.
There is a popular belief that the core team of four runs four times faster than single-processor computers. It does not work, but for programs that are designed to perform in the team of four cores. Codes written in these programs allow the processor to perform four different tasks simultaneously. Games like Gears of War or Crysis which require multiple audio tasks with the allowance of physics, AI or run simultaneously can be played through the multi-threading processors quad-core computer.
Performance wise quad core computers are faster in multitasking and parallel programming. For example, you can run multiple virtual machines with four processors. hardware virtualization to provide high-end playing video games, videos and photo editing, audio transcoding, data folding, 3D, installation of voice recognition, there are many options to choose from in teams of four cores. You can run virtual studio on XP, work on Photoshop projects in the core OSX install or make any other distribution program lunux. You can also run XP on top of the XP VM. You will be able to carry the maximum amount of virtual machines that ESX 3 is capable of executing. However, the number of virtual machines to run depends on the memory space on your computer in four cores.
Speaking of quad-core computers, worth discussing about certain models in the family of four cores. The Kentsfield is the first quad-core Intel desktop range. Its high-performance model was Core 2 Extreme QX6700 and mainstream brand was named as Core 2 Quad Q6600. Currently Intel has launched two new models: the Core 2 Extreme QX6850 and Core 2 Quad Q6700. Of these two, the Core 2 Quad Q6700 is just a modification of the Core 2 Extreme QX6700 adorned with a closed-core multiplier.
In fact, the Intel Core 2 Q series is just combining two entirely different Core 2 Duo, packaged in a single CPU socket. The L1 and L2 caches are different from the two sets individual base 2. Frontside bus architecture is used to communicate with one unit of external memory controller north bridge. The initial Core 2 Q6700 shows a clock 1066MHz effective FSB speed with a bandwidth of 8.5GB/sec and Core 2 Extreme QX6850 can go up to 1333MHz with a bandwidth of 10.7GB/sec.
Having said about the things you can do in a team of four cores, the question that is currently under debate is whether these quad-core computers are a real need of the hour. For example, performance and its speed can be achieved with a dual core CPU Core 2 E6850 and Core 2 Extreme QX6850. So why any user to opt for the quad-core series that are expensive than the Core 2 computers? It is a fact that for general use, today, Dual core or Core 2 is the best economic choice. Actually quad core computers were not designed for users in general. It's for high-end users who want to use complex algorithms programs, run parallel programming, multithreading and multitasking simultaneously.
However, with the arrival of more complex coding programming, quad-core computer is expected to be in demand in the near future. In fact, computer manufacturers are positive about a significant growth of quad-core computer users in a year or two.
