Core2Duo : Dual core processors
core2quad: quad core processors
core i3: dual core processors but are based on a newer architecture which takes less amount of power and is faster than core2duo on same clock speed. Also, this one needs newer LGA1156 socket whereas core2duo/quad used LGA775 socket. Another major difference is that core i3 has onboard memory controller and is compatible with DDR3 RAM.

in all round performance, Core i7>> Core i5 quad core >> mid-range core2quad >> core i5 dual core >. core i3 >> core2duo >> Pentium Dual Core.

and also these core i3,i5,i7 has threading features (hyper threading which gives high performance).and has separate processing for graphics.

all core ix are based on Nehalem microarchitecture and these links should give a good idea about this:

*en.wikipedia.org/wiki/Nehalem_(microarchitecture)
*www.intel.com/technology/architecture-silicon/next-gen/
*www.trustedreviews.com/cpu-memory/...el-Core-i7--Nehalem--Architecture-Overview/p1

One clarification regarding power consumption. Core i3 processors consume more power than Core 2 duo processors

Is it not the other way round..?
