If you’ve been working with computers for any length of time, you probably know that quad-core processors are faster than dual-core processors. But why?
Well, the answer comes down to simple mathematics.
Dual-Core vs. Quad-Core
As you may have already guessed from their names, a dual-core processor has two cores while a quad-core processor has four. The presence of multiple cores allows your computer to execute multiple processes at the same time.
However, more cores doesn’t always mean faster processing speeds. In the end, regardless of how many cores your system has, they all share the same memory and data path to the motherboard. So, while a quad-core chip may be able to execute instructions four times faster than a single-core (or twice as fast as a dual-core), this doesn’t mean it can receive instructions from ram four times faster.
So what does that mean for the average user?
In most cases, in order for more cores to really make a difference, its going to depend on what you’re using them for. In other words, if the software you’re running doesn’t know how to properly utilize twice the amount of cores, then it won’t execute tasks at twice the speed.
