i7, i5 and i3 HTT

[Caveman]

Hey guys,

Just a quick question as im a little curious.

Ive read that the i7 CPUs have HTT (Hyper Threading Tech) and that the i5's dont which is somewhat understandable, more reason to people to buy the i7 over the 5s however ive also read that the i3 CPUs have HTT, is this true? If so, how come? I would have thought being bottom class chips they certainly wouldn't come with it especially if its big brother didnt.

Unless I am mistaken?

Thanks.

The i3s have 2 physical cores with hyperthreading, allowing them to handle 4 threads. The i5s have 4 physical cores but no hyper-threading - this means they can also handle 4 threads, but they can do it better than the i3s (due to having 4 actual cores, rather than running 2 threads on one core). The i7s have 4 physical cores and can also hyperthread, allowing them to handle 8 threads.

So yes, the i3s and i7s can hyperthread where the i5s can't, but the i5s still have more cores than the i3s, making them overall better chips.

Hope that helps

Yes. The i3 processors have hypertheading enabled by default. The i5 processors do not have hyperthreading because of the 4 actual cores as the i3 has 2 cores and 2 threads. However, the i5 is an overall better processing unit than the i3 because of the 4 cores.
