Why is it that Intel Core 2 Duo processors seem to have a slower processor speed than the older Pentium D?

Question

For eg, the fastest Core 2 Duo is something like E6800 2.66 Ghz where as the fastest Pentium 4 processor is 3.8 Ghz. Is this speed disparity b'cos of the 2 cores doing their job. In any case there are hardly any commercial applications that actually use both cores simultaneously, i mean there are no multi-threaded applications anyway..so whats the whole point in buying a Core 2 Duo computer ??

Answer 1

the core 2 duo chips do not have as high of a clock speed as compared to a Pentium 4 chip because the higher clock speeds produce way more heat. The core 2 duo chips have benefits over the Pentium 4, such as a larger cache, that help its performance as well. Although there are not a lot of applications that use both cores, two programs can each have a core to themselves. This is where the performance gain comes in as 2 programs each with their own core will run faster than if they had to share the same processor (such as on a pentium 4)...

Answer 2

The Core 2 Duo running at 2.66GHz is running two cores at 2.66, which in turn equals 5.32GHz, obviously better and faster than the little old 3.8 single core.

Answer 3

Intel middle by way of fact first that's extra recent and the L2 cache is better meaning that that's able to working extra courses extra appropriate gaming. yet in terms of enerygy use the middle makes use of extra by way of fact it has a twin technique that helps extra appropriate velocity and makes use of mroe potential to run courses.
