And i want to ask another thing i know that there is already a post about CORE 2 DUO and DUAL CORE procesors. But how much diffrence is between CORE 2 DUO and DUAL CORE procesor ?
This really should be it's own thread. The other guy that asked the question lumped it in with upgrade questions as well...which is why it wasn't answered.
Simply: A Core 2 Duo CPU
is a Dual Core processor. It is one physical CPU package, but behaves as if it were a dual CPU package system. The processor is built to process two threads at the same time, in the same way that Symmetric Multiprocessing (SMP) works. A Core 2 Quad CPU is a Quade Core processor, meaning it can process four threads at the same time.
The original Pentium 4's were not dual core. They had a feature called Hyper-threading that enabled Simultaneous Multithreading (SMT). This was supposed to give performance equivalent to SMP, but in most cases it didn't. The only place it really worked was if the application was specifically coded to take advantage of both SMP and Hyperthreading at the same time. Most developers didn't even bother...
