Hello, what is difference between i3 and core 2 duo?
More aboutwhat difference core
core i3 is newer. it is 32 nm meaning it can oc higher, use less energy, and run cooler. they have HT, which means even though they are a dual core, they show up as having 4 threads, and a few other things. basically the i3 is better than most core 2 duos, and definitely cheaper.
yeah, on good air, the i3 can get 4.2 GHz plus easily, where as the core 2 duos might barely be able to go past 3.8 GHz, but it depends on the cpu.
