well in that case can u explain me y intel c2d is faster than my cpu which is 2.8 GHZ HT with MOBO 865 GBF .. i always thought the more the GHZ teh faster the CPU but now imknow theres something more 2 it .. wat is it?

More GHz is faster is true only for a particular CPU family. So amongst all Pentium 4 chips or amongst all Core 2 Duo chips, the faster the clock speed, the faster the CPU. However you can't compare the clockspeeds of differing architectures as they will have different IPC (Instructions per Clock Cycle). Finally what matters is how many instructions a CPU can execute in a clock cycle. A CPU that executes 5 instruction per clock and runs at 1GHz will be faster than a CPU that executes 1 instruction per clock cycle and runs at 3GHz. How many instructions are executed per clock cycle depends on the architecture, pipeline length and many other factors. In layman's terms, an E6300 Core 2 Duo running at 1.86GHz is faster than any Pentium D ever made (3.73GHz) since it has way better IPC...

NICELY DONE!!!& yes u r absolutely right.AMD cores always work on lower clock speed but they are named as 3000+,3200+,3500+....so on.But a 3200+ will have a clock speed of 1.9 GHZ.They are named as 3200+ because they can perform same or more than INTEL's 3.2 GHZ processors.

after p-3 intel made something good and better than P-4 and P-D {820 series)

bcoz c2d execute 4 instruction per cycle under favorable conditions(idle conditions) all netburst CPU (P-4 and P-D execute Approx 2 instructions per cycle) so the c2d does approximately twice the work per MHZ then netburst CPU (give a take a few % points)
