What the go with the intel i3

X79

Honorable
Yes.

That's due to hyper-threading.

The i3 has 2 cores, but HT gives it another 2 virtual ones.

This is also why i7's are so wanted for tasks that need heavy-lifting (video/image editing), because

the i7 has HT as well, but has 4 physical cores. Thus thanks to HT it gets another 4.

In the end that results in more cores and more horsepower.
