intel dual core cpu's?

Question

why are the speeds so much slower than the predecessor cpu's. do the dual core run faster only when processing multiple tasks and slower when only doing one?

Answer 1

The clock speed in Ghz is not the only thing that determines the speed of a processor. The front side bus speed, the amount of cache, and the amount of data sent each clock cycle all help to determine speed. The new Core 2 Duos are superior in all of these areas, so they are faster even when doing a single task.

Answer 2

Yes your supposition is correct, this dual coring is a technical extension of dual CPU found previously only on top of the line server components. However the multiple tasks you mention includes a technique call multithreading, think of it as multitasking in a programming level within one program, if the program uses multithreading it would run faster in dual core. Obviously gaming studios would take advantage of this.

Answer 3

Sadly to say, "This is true" dual core is more usefull in multithreaded operations where multiple threads or applications running in background. In case of single thread they runs as a normal processor ('coz only one core handles it, not all) Or one more, these cores are not always works together means if work load is too low or a very small app is running than it is possible it will handled by only one core without awakening other cores.

TIP:: Increase ur RAM as much as u can, i recommend to fullfill all ports to their maximum limit to optimum performance.

Answer 4

dual core cpu give marginal improvement on program that is not specialize in mutithreading. is not due to their dual core, is due to their increase and optimization in FSB, cache, etc. So you might also notice there might be some single core CPU out performing a dual core CPU at certain applications.

but just to let you know, programming in muti-thread is a pain
*atleast for me*
