Many a times, this question arises for clients looking for Dedicated Hosting as to which one is better, a Dedicated Server with Single Core Processor or a Dedicated Server with Dual Core Processor. The answer is offcourse Dual Core, however, the reason for this is not known by them. Below are few lines which will explain the difference between a Single Core Processor and a Dual Core Processor.
Single Core Processors have a single processor in a single die, whereas, a Dual Core Processor has double processor in a single die which makes it faster and better in comparison to Single Processor.
In a single core processor, there are a number of instructions which are given to the CPU which has to be executed by the CPU in a proper manner and then stored into the cache so that it is possible to retrieve it quickly. Incase, the data which is not stored in the cache is required, Random Access Memory (RAM) or any other storage devices are used by the system bus in order to fetch the information. Now, if the data is to be fetched from the RAM or storage device, the performance is affected as the speed of the CPU is slower. Due to this reason, the processor might not perform well when it comes to handling a number of processes at the same time as it will have to switch from two or more sets of data which are different streams and programs.
When it comes to a Dual Core Processor, incoming data is handled by 2 different cores at the same time which improves the overall performance. As there are 2 cores, the result is retrieved faster and is better.
Hope this short explanation helps readers to differentiate between Dedicated Servers with a Single Core Processor and Dual Core Processors
