why intel i7 only 1.6GHz?
what id the difference between quad core and i7?

More about : core 6ghz

Quad core just means that a processor has 4 cores, there are many different quad cores, an i7 is just one type of quad core, there are also Athlon II X4s, Phenom II X4, Core 2 Quads, i5s, and Phenom I X4. I assume you are looking at the i7 720QM for a laptop? They drop the speed down to give it lower power consumption to save some battery life but it has a pretty good turbo boost setup so it can kick up to higher speed when needed.

There are 2 "main" types of i7 processors. Mobility/Laptop versions and the desktop ones.

Quad core means having 4 cores on a processor. All i7 processors are quad cores, and there are many types as hunter315 has pointed out - the i7 is not the only quad core processor out there.

A laptop quad core will have much slower clocked speeds than their desktop counterparts because they are designed to operate in more 'compact' and 'on the move' situations, such as lowering heat and power. In this case, you could say they are a 'stripped down' version of the desktop i7 processors since they are specifically designed for running on laptops. However, all of intel's i7 processors come with native "turbo boost" technology so they can easily be clocked to higher speeds for better performance.

If its a laptop Core i7 720QM, the stock speed is 1.6GHz.

If not then its Speedstep lowering the clock speed in order to lower the heat and power consumption.

I7 is also used for 6 core desktop processors. Intel really screwed up naming when an I7 970 has 6 cores, I7 975 has 4 cores, and I7 980 has 6 cores. lol

they also messed up the i7 name with the 860/870 (1156 instead of 1366)

not true.

i7's were originally supposed to be processors that can run 8 threads and support TB. Therefore, the naming scheme of the 860/870 makes sense. Intel used the 800 series to represent i7s on the 1156 platform and the 900 series to represent i7s on 1366 platform.

What doesn't make sense is what loneninja said when they introduced 6-core cpus into the i7 naming scheme.

^I think the i7 name was more meant to go up to 8 cores/16 threads.
