i7 is faster
the i7 920 has 2.67 GHZ with 4 cores and 8 threads, and the i7 940 has 2.93 GHZ with 4 cores and 8 threads. both can be overclocked easily. but if you are not planning on overclocking, the i7 940 is faster.
I7 supports Hyper Threading, turbo memory, triple channel memory, and some new CPU instructions which makes it faster than Intel Core 2 Quad.
core2duo is faster but corei7 is much more faster because it can open many program at a time, it includes more graphics
An advantage of the Core i3 processor is that it is faster than previous processors such as the Pentium 4. A disadvantage is that the i5 and i7 are generally faster.
Of course, I7 is better. First of all, it's cheaper. Second, it does not have problems with heat. Third, if you overclock it, it outperforms (thanks to Hyper Threading) QX9650 even if it was overclocked too.
It think there is a difference of 40qm ! Lol
It depends really. If you're looking for a fast but more budget-friendly CPU, the i5 is better. But it lacks some features that the i7 has. Nevertheless, it is still a good, fast CPU. The i7, on the other hand, currently reigns as king and its prices reflect that. The Intel core i5 and i7 features both hyper threading technology helping it do multitasking and can boost the ghz up to a higher ghz. But the difference between the i5 and i7 is that i5 has two cores and i7 has 4 cores.
Intel core i7-920
the i7 is better the i7 have 4 physical cores and 2 threads per core the core 2 quad have 4 physical cores and 1 thread per core. the i7 also have a technology called turbo boost to boost the performnce of single core apps

Nehalem is the name of the architecture. The Intel Core i7 is a chip based on that architecture.
