As instructions are promgrammed and data is processed by processors, there are different ways a processor can operate. Therefore, there are different types of processors. There are two main types of different processors: Dual Core processor and Dual Processors. Also remember that different brands are different in how they make the processors, and they may be different quality. The two biggest brands, which are competitors are: Intel and AMD

DUAL CORE PROCESSORS have been the new solution to more complicated performances of computers. In the 21st Century, people have the desire to perform many different tasks on the computer so manufacturers have designed the Dual Core Processor to increase speed in order to keep up with the performance demands. The Dual Core processor is not double the usual sized processor, nor does it produce an excessive amount of heat, instead it is one small chip with two CPU's put together, so it's alot more useful in terms of money spent, and space taken up on the motherboard. The many different brands vary in the size, how the two processors are put together into one, and the speeds that each core runs, however all dual core processors are very useful.

Advantages of using a dual-core processor include:
-Operates quicker as signals don't have to travel off-chip.
-Signals are less corrupted as it travels a shorter distance.
-It requires much less PCB (Printed Circuit Board) space.
-Doesn't produce double the heat.
-Operations are a lot more quicker as there are two chips.

Disadvantages of using a dual-core processor include:
Most software applications available can't use dual core processor.
-quite expensive to buy

DUAL PROCESSORS are slightly different to dual-core processors. Dual processors are again two processors, but instead of being combined as the physical traditional processor design (on one chip), there are two actual chips that are positioned seperately on the same motherboard, or on different motherboards. This uses up more space on the motherboard but can still operate insrtuctions faster than two.

Advantages of using a dual-processor:
provides full power on a single task.
-impacts the speed of multiprocessor programs such as adobe and video editors.

Disadvantages of using a dual-processor:
-main cause of overheating.
-more expensive to buy the two processor chips.
-motherboard should also be capable of inserting two processor chips, otherwise, dual processors can not be used.
AMD vs. Intel... who will win the fight?
AMD vs. Intel
For many years, Intel was always the leading brand for processors but now a new challenge has risen from AMD. These now leading top two processor brands are competing for the best and new devices to sell to their customers who want best performance and quality. As mentioned before, different brands design and make dual-core processors differently which therefore differs in quality. Intel and AMD are the major manufacturers of processors. The problem though is that they are limited by Microsoft's limits aswell. The thing is... which one is better to buy??
AMD processors haven't been a real competition until they started coming up with a few new designs. They are now known as the one of the top brands in the market who 'challenges' Intel. The advantage they have over Intel Processors are that the processors they create are more energy efficient (their designs use less energy). AMD processors are also alot cheaper in price, still with the good quality and up-to-date processor technology-that is caught up with Intel. AMD have made it possible to increase the amount of chips combined in one, and also reducing the amount of heat, for example the Athlon 64 X2.

Intel has been the major processor manufacturer for a very long time (established in 1980), being the first to create a processor chip. Although AMD is successfully catching up to their technology and new designs, Intel is always the one to beat them. Intel have come up with many different processors, creating the current fastest processor ( Intel Core 2 Extreme on July 16 2007). Intel have also started producing quad-core processors which AMD have yet to do.
Amd and Intel are both similar manufacturers of processors. These top two marketers have bargained for the best processors inthe world. Intel and AMD are both capable of making the latest technology with processors and good quality processors, although it will take little time until the prices will start coming down. AMD is probably the better choice for most average people who want good processing quality as it is cheaper.
Different brands and different types of processors offer different prices to consumers. In April 2007, Intel and AMD were seen to start a 'price war'. These two brands are in a definite competition, trying to sell the most processors and cutting down prices, predicted to even half the prices. As they introduce new, high performance processorseach year, they have have also strategically dropped prices to sell-out their products. Average prices of processors have dropped by 28%. As of october 2006, the top 15 processors average in a price of $379. Click here to see the statistics on average pricing of all processors and also Intel vs. AMD:
