What is the difference between dual core processor and a single processor?

Answer 1

A single core processor is just that... one processing core. A dual core processor is actually two processing cores on one chip. It is like having two processors in your system, but it is faster than two individual processors.

There are exceptions to the rule. For example all things being equal, a 3.8GHz Intel Pentium 4 single core utilizing hyperthreading is going to be about on par or faster in some scenarios with something like a 2.2GHz dual core processor.

A major problem with high performance multiple core processors are they are becoming faster than the minimum RAM installed by many companies' low to mid-range computers. This increases thrashing, meaning the CPU is processing more information than can be stored in the RAM. It is a similar thing which happened with older single core processors about 15-20 years ago. New CPU technology is outpacing storage memory. You can upgrade to more RAM but currently is very expensive for these newer computers. (as of 2010)

Answer 2

The difference is that normal processor are single core. With dual core processor, you can get better performance as the programs are spread out into 2 processor rather than 1 processor. •Single core

•start one operation a time

•start a new operation before the first one has complete

•slower and not stable, easy to hang

•if a program crashes the system will hang and wait for it to responds

•Dual core

•start multiple of operation in a time

•two single core processor combince into one

•faster and stble

•the program has use of one core, leaving the other core free for other program, such as Tssk Manager, so the dead program can be closed

Answer 3

A dual core processor is a single processor that has two processing cores. A dual processor system is a system that had two individual processors. Their motherboards have two processor slots. Usually pretty pricey.

Answer 4

A single-core processor has only one primary integer core, instruction set, and the sort. Multi-Core processors have 2 or more of the above mentioned, and as such have more complex pipelines and the sort. Serial Multi-Core processors have gone up to 6 full cores or 8 full modules in AMD's case for desktop processors, and much higher in server scenarios. Parallel processors, such as those used in graphics cards, have multi-core processors ranging in the high hundreds of cores.

Answer 5

single core is a tradisional processor but multi core is a combined of two or more of independent processor
