is intel Core 2 Duo Processor P8700 (2.53GHz / 1066MHz FSB / 3MB) better than core-i7Intel® Core™ i7-720QM Processor (1.6GHz, turbo up to 2.8GHz, 6MB L3 Cache) ? how comw core i7-720M (1.6GHz) is costlier than core 2 duo P8700(2.53Ghz) as latter clock speed is higher??

the i7 is theoretically better, tis a new technology, hence why it costs more, and can be faster that the p8700 with turbo boost. has the memory controller onboard, new architecture etc...

The i7 is newer and it's a Quad Core. It's only runs at 1.6Ghz when there 4 cores working and then it's probally at 1.73Ghz most of the time. When there is 2 thread it runs at 2.4Ghz (just behind the P8700) and with 1 thread it's at 2.8, so quicker.

I'm sure the i7 would be faster in other area's like DDR3 and so on.
