The cost of Quad core processors depends on the brand. AMD sells them for cheaper i.e. $170 whereas Intel sells them for a little more cost i.e. $199. I personally feel AMD is better as it gives the same result at a better price.
Intel Dual Core is much better! :)
The cost would depend on the processor you wanted to purchase. An upgrade is probably possible (the Pentium Dual-Core is based on the Core Duo and Core 2 Duo processors) but you would need to make sure your motherboard supports the proper FSB speeds for your processor of choice.
The Intel Pentium Dual-Core is much faster.
dual core processors allow for twice as much data processing thus making computer much faster and stable.
No. A Pentium Dual Core is a cost-reduced version of a Core 2 Duo. Think of it as the new equivalent of a Celeron. The Pentium D is basically a dual-cored version of the Pentium 4, but is far less efficient than a Core 2 Duo (or a Pentium Dual Core).
What is the new proccessor launched?
Core 2 duo is dual core. And before that was core duo which was dual core too...
There are Celeron dual core processors today. However, just because you have Celeron processor, it does not mean your Celeron processor is a dual core processor. The easiest way to tell is to look at the Intel sticker on your computer. If it says "Dual Core," then it is dual core. If it does NOT say "Dual Core," then it is not dual core.
difference between dual core and core i3
sempron is not a dual core processor.
Dual core represents two processors in a single system.Speed will be more in dual core systems.
quad core has 4 cores a dual core has 2 cores
