Dual core Vs Dual Processor
 
A major question for some people getting ready to buy a high-end system is whether they want or need to have two processors available to them. For anyone doing video editing,
multi-threaded applications, or a lot of multitasking the answer is a very clear 'yes'. Then the question becomes whether two separate processors (as in a dual Xeon or Opteron ystem) is the way to go, or whether a single dual core processor (like a Pentium D or Athlon64 X2) will do just as well. Dual CPU vs dual core -- which is better?!


Intel did not increase the speed of their front-side-bus (the connection between the CPU and the motherboard) when they switched to dual-core, meaning that though the
power doubled, the amount of bandwidth for each core did not. This puts a bit of a
strain on the Intel design, and likely prevents it from being as powerful as it could
be. To counteract this effect, Intel continues to use faster system memory to keep information supplied to the processor cores.

AMD, on the other hand, does not use a front-side-bus in the traditional sense. They use
a technology called HyperTransport to communicate with the chipset and system memory,
and they have also moved the memory controller from the chipset to the CPU. By having
the memory controller directly on the processor, AMD has given their platform a large
advantage, especially with the move to dual-core. The latest generation of AMD single-core processors can use single- or dual-channel PC3200 memory, but it is interesting to note that even though dual-channel operation doubles the memory speed, it oes not double the actual memory performance for single-core processors. :charming:

Re: Dual core Vs Dual Processor
 
the diff between dual core and dual processor is that in one the processor are in parallel and in the other it is in series.the concept is similar to that two resistances are atttaced in parallel or in series.for processor the formula is interchanged as in case of resistance.therefore one is better than the other.

Re: Dual core Vs Dual Processor
 
yea......it really depends on what your wanting to do with this machine.......
if u want some high end hardware, check out alienware, they have some great machines with Intel's new quad core processor tech.

Dual processor means two processors are available with motherboard for doing multi-threading ,multitasking or perform other processing.For example we can say two separate processors as in a dual Xeon or Opteron system.
But Dual core processor has single processor with dual(two) cores for example in a Pentium-D ,Athlon64-X2. It will perform the task also multithreading etc.
Dual core processor is cheaper then dual processor because dual processor will take two CPU that will costly compare to single CPU with two core processor.
