how is a dual core processor different?

A dual core processor is exactly what it sounds like. It is two processor cores on one die essentially like having a dual processor system in one processor.simply means a faster connection that is able to transfer more data between two chips. This does not mean that the chip itself is faster. It means that the capability exists via the HyperTransport pathway for one chip to “talk” to another chip or device at a faster speed and with greater data throughput. \nTwo pairs of hands make the work go faster. This is quite true in computers with dual processors especially with SMP (Symmetric Multiprocessing) software.

Core Duo is just a dual core, Core 2 Duo is Core Duo improved, so its better to go with Core 2 Duo

Intel Pentium D, or popularly known as Intel Pentium Dual Core CPU is one of the first multicore cpu's available in the market. First released in the spring of 2005. They use 2 cores on 2 dies. \nYou can read more about them here\nhttp://en.wikipedia.org/wiki/Pentium_D\nhttp://www.intel.com/products/processor/pentium_D/index.htm\n\nIntel Pentium M, popularly known as Pentium Mobile chips are processors manufactured exclusively for mobile performance. Lighterweight and faster performance are some of its key features. you can read more about it here.\nhttp://en.wikipedia.org/wiki/Pentium_M\nhttp://www.intel.com/products/processor/pentiumm/index.htm\n\nIntel Pentium 4, popularly known as P4 chips were the next level of processors after the Pentium III. Faster computing speeds were one of its key features. You can read more about it here.  \nhttp://en.wikipedia.org/wiki/Pentium_4\nhttp://www.intel.com/products/processor/pentium4/

You mean "dual core".\nIt puts to processing cores on the die which makes it faster, not quite double speed, but faster.\n\nA kernel is something different.

The main advantage of a multi-processing system is the dual core CPU. It makes multitasking so much more managable.

Acutally, Intel Core Duo ONLY refers to the dual core Centrino systems with a Intel "Yonah" Processor, Intel 945 express chipset, and Intel Pro/Wireless 3945ABG Network Connection. (I'm pretty sure that the laptop can still be called "Core Duo" if the wireless card is replaced with a similiar non-Intel-brand one.)\n\nThe processor speed is the maximum non-overclocked speed at which EACH processor runs. Although there are two processors, you'll never get close to doubling the speed of a single processor. Practical gaming, business, and synthesis benchmarks show that average improvement in using 2 processors is anywhere from 0-30%. Multithreaded processes will see more benefit.

In Amd The are two good processor amd athlon 64 dual core & amd athlon x2 both the processors have very high performance i should prefer u amd athlon 64 dual core processor.

There is a big difference in the architecture of both CPUs. An AMD CPU has an integrated memory controller. This serves as a link between the CPU and the memory (RAM). Intel CPUs do not have this, so it relies on another chip to serve as the link with the memory. This saves up space on the CPU, so Intel decided to increase the cache size on their CPUs.\nMore details.\nBecause AMD has the integrated mem controller, it performs faster than an Intel CPU with same clock speed. You have to know that it is not the CPU clock speed that matters, but the FSB clock speed. So if you need a 'fast computer' you need a lot of memory (RAM) and a high FSB.

duo-core processors are 2 different processors but are linked. the reason they have this is it makes processing faster. if you have one single processor..it does all the work, it has to process that much more stuff. the duo-core utilizes 2 seperate processors to make the computer run faster, only one of the processors will be doing the job (and have to process less). if you have a duo 1.83...it has the equivalent of a 2.66 ghz processor. but when you choose to do something, it only uses the one needed (1.83) and it doesn't have to process as much info as a normal 2.66. and yes if one processor fails..neither are any good.

D = Dual Core. Two cores are better than one and the price is right. It's like having two CPU's instead of one to a degree, it's not totally the same as there is the I/O bottleneck.

Now that the processors are pretty similar, the difference comes to the look the computer and your preference for the operating system (OS X for Macs and Windows XP for PCs).  The best way is to try each one out in a store before you buy and then make your decision.

Go for the dual core.  It is faster and more stable if you are like me who like to run many things in parallel.

The simplest answer is Intel Core 2 Duo is definitely faster than Intel Core Duo.  In other words, Core Duo is the first version of Intels dual core processors(2 processors in one) and Core 2 Duo is the second version.  \n\nThe longer answer is that within the last few years, everyone has realized that core speed (such as the 3.4Ghz or 1.86Ghz you mentioned) are not the only thing that determine speed.  Think of it like this, imagine that there were two autos you were thinking of buying.  One is a huge truck with a big engine, maybe a 6 Liter engine.  The other is a small sports car with only a 3 Liter engine.  Even though the truck has the bigger engine, the sports car will actually be faster.  So if speed is what you are after (which is really the main reason to buy a processor) then you will buy the sports car.  \n\nBottom line, buy the Core 2 Duo.

no. one is for amd processors and one is for Intel processors. different technology

Software that is written to take advantage of a dual-core processor will allow both cores to work together to complete a task. You won't get true 6 GHz performance, but it will be significantly quicker than if you were running a single core 3 GHz processor. One complaint about the Pentium D chips is the two core use the Front Side Bus to talk to each other, therefore, the processor speed is limited when the two cores are working together. I'm running a Pentium D 830, and aside for an increase in my electric bill, I'm happy with it's performance.

apple dual core, 2 operating systems for the price of one, has many cool features. handles high end design programs without a hitch.
