Computer question.

Hello everyone,

The following question may sound stupid to computer guys.

Is a dual core 1.2 GHz processor as fast as a single core 2.4 GHz processor?

Thank you,

Mariano

Only if you run software that can distribute itself perfectly over two CPUs. This software is rare to come by. Furthermore the dual core design is not exactly a duplicate single processor, and there are always losses in coordination overhead. Lastly, GHz counts say little unless you really have the same type of processor, as execution efficiency depends on so much more than clock GHz.

Thank you Jeroen. As I suspected it, not such a simple matter ;-)
