What is the difference between Dual Core - i7?

[Jaden]

What is so different about the Dual Core and Intel Core i5 and i7 processor series? Aren't they the same thing, but named differently? Is i5 a dual core, but better? And a i7 like quad core, but better?

i7 and i5 are much faster than dual core. thats it.

i7 and i5 cores are faster than dual core because the normal dual cores are from a older family of processors.The Core i7 and i5 is a completely new architecture which is much faster and more efficient than the Core 2 Duoi7 and i5 processors has cores ranging from 2-6 cores and has many hyperthreadings

In a way, yes, the i5 is comparable to core 2 duo and the i7 to quad core. However, the biggest difference is that the i5/i7 processors can overclock themselves for better performance and downclock themselves to save energy and produce less heat.

.The i5 uses dual channel memory while the i7 uses triple channel memory.
