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.
