Hi guys,

This is just for the sake of the knowledge.As the name goes I want to ask what the speed of a multicore processer means. For example , say a Core 2 Quad has a speed given to be 2.5 Ghz. So do this refer that the entire CPU has a frequency of 2.5 Ghz or each of the 4 core has speed 2.5 Ghz (i.e. Full speed is 10 Ghz) ?

It means that the entire CPU i.e. all cores run at 2.5 GHz. That doesn't make it 10 GHz.

Unless you follow the ebay rules of advertising PCs

Also note that 2.5 does not equal 2.5 i.e. amd's 2.5 is not equal to intels 2.5, and ivy bridge 2.5 is not equal to sandy bridge 2.5

Yes, thats what I wanna ask.I wanna buy a AMD Phenom 2 x4 965 3.4 Ghz as it is cheaper compared to Intel Core2Quad . Would it be a compromise ? Main purpose is gaming.

PII 965 is possibly the best that amd produce, perhaps until the last set of releases so its good. There is always a compromise, its not a bad one here.
