If you’re good at math, you may have figured out that hyperthreading is actually creating four cores out of the two available cores. With hyperthreading, your dual-core Intel i3 will perform better than any normal dual-core processors especially when it comes to multitasking. This helps deliver more performance per physical core while also saving power. In layman’s terms, hyperthreading is a technology that lets a single physical core act like two cores thus improving multitasking without the need to activate another core. You can learn more about processor cores by heading to our dedicated article explaining the difference between dual-core and quad-core. Some extreme versions can have six or eight cores but there are hardly any applications that utilize more than four cores.
Similarly, all desktop i7 CPUs are quad-core, at the very least. But don’t worry, there is an easy way to figure out how many cores a processor has and we’ll talk about that too.Įven though some i5 processors are dual-core, they will outperform an i3 dual-core thanks to Turbo-boosting. If you’re talking about desktop CPUs most i5 CPUs are quad-core except a rare case here or there. Especially when you consider mobile i5 CPUs such as those used in a laptop or an ultrabook. Coming on to i5, these can be quad-core but there are also dual-core variants. These processors are dual-core but support Intel’s hyperthreading technology which we will discuss in a bit. Core i3 processors have the lowest core count which shouldn’t come as a surprise.
