I have a Dell Inspiron 5160 Laptop that I am looking to upgrade into a desktop. The laptop I have has a Pentium 4 processor which has had a memory upgrade from 512 to 1GB. Now I am not to sure of the detail on this but when I look at the system in my control panel, it says that I have 2.8ghz on the processor (CPU) and 1.25GB of RAM. When I compare these to the stats to the new intel Processors (Intel Duo – core) it seems as though the processor in my laptop is faster than the duo core ones! Surely this cannot be right?

The speed in Ghz is not the only factor that affects speed. You have to look at the speed of the FSB, the amount of cache. and the amount of data per clock cylce. The new Core 2 Duos are superior in all of these areas, which is why they end up being faster than a Pentium 4 that has a higher clock speed. Now a lot of people have pointed out they have two cores, but this is not the reason they are faster, they would be faster even if they had just one core.

I upgraded a Pentium 4 3.6GHz to a Core 2 Duo 2.4GHz and the performance boost is amazing. The Core 2 Duo rapes several times over my "faster" P4
Then I overclocked it to 3.2GHz (Conroe)

Theoretically, a processor running at say 3.0 ghz is faster than a duo core processor running at say 2.0ghz. The duo core, however, allows you to manage twice the number of processes at a time , distributing the processes over 2 processors to better handle the load. :0)

well in duo core there are 2 cores that are used for processing..
it is like having dual processors(not same processing power but still good)...
when u have 2.4 GHz core duo u would have 2 cores with individual speeds of 2.4 GHz (mind it thats not 4.8 GHz)...work can be divided between the 2 cores so parallel processing is achieved resulting in faster operation than a single processors for applications that are made for dual processors( the no. of such applications is small though)...
in future we can expect dual cores and even quadcores to take over our PC brain..................

I was puzzled by this at first. The Pentium 4 has a faster CPU number, but it is not a faster processor. I cannot explain it.

it looks to be but its not, intel duore 2 is like having 2 PCU's,
