Seeing 4 Cores on i5 MBA

[claughery]

Hey... Just upgraded MBA yesterday to i5 from c2d. I am noticing 4 cores in the activity monitor.... Am I seeing correctly? Why is this???

Two cores + Hyper-Threading = Each core can process up to two threads simultaneously = Four threads in Activity Monitor

Hyperthreading.

I didn't know about that either until I observed my MBA converting a 720p video with Handbrake about 1/3 faster than my two year old iMac.

Tech is quite amazing and so is the MBA
