Ok so the Core 2 duos are really fast but why when you can buy a pentuim 4 at 3.0ghz and then you can buy a Core 2 duo thats 2.6ghz Id figure the pentium 4 would be faster since it has 3.0ghz. So why is the Core 2 duo so much better than the pentium 4 and any other processors?
Pentium 4 are far less efficient than Core 2 duo for a start, the clock speeds on P4 needed to be high because it had something like a 31 stage pipeline which slowed things down. The Core 2 Duo has about 14 stages i believe and can therefore do more things in the same period of time. It also has far more advanced brach prediction so it can see whats coming.
Plus the fact its built on a 65nm process so it runs cooler and has shorter distances between transisters, and of course, it has 2 processors running as opposed to 1. I suppose you can get dual core pentium 4 but they were a bit of an ad-hoc solution to getting Intel on the dual core starting grid and dont scale half as well as either Core 2 Duo or the AMD competition.
Hope this helps.
The Core 2 Duo's have two 'cores'. A core is another word for a processor. And therefore, the Core 2 Duo has two 2.6GHz processors, on the same chip, making them significaintly faster.
That should help.
Rookie_42;3348467Because, quite simply, Core 2 Duo is much, much more efficient
better chip design.
Just goes to show clock speed isn't everything.
Alrite finally someone explains to me thanks alot guys.
