I get confused with core i3 first gen. and dual core 2nd gen. processors. Can some body explain me which is better as I am looking to buy one of them. Also let me know if I can run windows XP professional on any of the two above.
as for physical differences, the i3 370m is a last gen dual core+ hyperthreading(its sorta like a pseudo 2 cores, not as good as 2 physical, but can be used similar to one)
the pentium chip will have the sandy bridge architecture, which is a significant boost compared to the clarksdale, but its solely a dual core chip.
On programs that require 2 or less cores to operate, I would think the sandy bridge would have enough power to overcome the .2 ghz difference between the 2 processors, but on ones that can utilize hyperthreading, the i3 370m I would think will have a slight advantage.
