But as a general rule of thumb, a quad core processor will draw more power from your laptop (and thus make it run out of battery faster). When the processor is switched on, it supplies power to all the cores, not just one at a time.Д¬hip makers have been trying to reduce power consumption and make processors more energy efficient. More cores also lead to higher power consumption by the processor. A newer dual core CPU with a higher clock speed will often outperform an older quad core CPU with a lower clock speed. The clock speed of each core also is a crucial factor in speed, as is the architecture. Not all programs are developed to split tasks between cores. More cores are faster only if a program can split its tasks between the cores. It's a little more complicated than that. You might think more cores will make your processor faster overall, but that's not always the case. How Speed Is Affected by Dual- and Quad-Core CPUs

We have a separate post on understanding smartphone cores. quad core processors for computers, not for smartphones. Essentially, each core is a central processing unit (CPU). That chip can have one, two, four, six, or eight cores.Д¬urrently, an 18-core processor is the best you can get in consumer PCs.Д®ach 'core' is the part of the chip that does the processing work. Let's cut the jargon and understand what it all really means. Do you need a dual core, a quad core, a hexa core, an octo core. But there's a lot of jargon, especially the cores. When you are purchasing a new laptop or building a computer, the processor is the most important decision.
