It's not always about how many cores you are running it's about what software you are running on them. Here's the dirty little secret that chip manufacturers don't want you to know. Like we said earlier, clock speed, architecture versions, and other considerations come into play. Are Quad-Core CPUs More Expensive Than Dual-Core? But again, as a general rule, more cores lead to more heat.ĭue to this additional heat, manufacturers need to add better heat sinks or other cooling solutions. More factors than the core affect the heat generated by a processor. 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.Ĭhip 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. More on this later.Įach core's clock speed is also 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.
