Pentium D was the first dual-core cpu.
Intel
I am not sure but i think the intel core i7 uses Hyper Threading to make it look like it has 8 processing cores
Dual core is the property of having two cores in a single CPU. Core2Duo is an Intel CPU that has two cores.
no
It means that it contains 2 cores with 2.2 GHz each. For applications that are made to use multiple CPU cores the speed will be as if it was one 4.4 GHz cpu. However, for programs that can't use it it will only be as fas as a single 2.2 GHz CPU, as only one of the cores would be used.
That means that your computer has two 2.80GHz cores. It's basically an Intel Duo Core 2.80GHz.
Pentium 4 vs. Dual CoreThere are MANY differences between these two generations of Intel CPU's. Most notably, Duo Core CPU's possess two processing cores opposed to the Pentium 4's single processing core. While a Duo Core CPU may be operating at a lower overall operating frequency, it is still much more powerful then a Pentium 4 considering it's improved FSB speed, cache size, multiple cores, efficiency, etc.
The first CPU chip was released on November 15, 1971 by Intel. The processor was called the Intel 4004 and was a 4-bit CPU.
One graph - one core inside your processor. Two graphs - two cores inside your processor. Four graphs = four cores inside your processor. And so on... This could also indicate the presence of Intel's "Hyperthreading" which allows a single core to act as two cores as far as the OS is concerned.
The first dual core CPU for the high-end / server market was the Intel "Itanium 2 (Montecito series)" processor. It was released in 2006. Besides that also the "Intel Pentium D" and the "Intel Pentium Extreme Edition" offered two cores. Both have been released in 2005.
The Intel 80486.
Improved AnswerA dual core CPU means that the processor (chip) has two cores built into it. You can think of a core as a brain, which allows the processor to do more calculations at once. If you yourself had more brains, you would be able to do more at once. It is the same concept with processors. Having more cores doesn't actually mean you have a better processor though. Since an Intel i5 can take on an AMD 6 core processor.Original Answerit is a single cpu with multiple cores that work together. i am building a computer that has an 6core AMD processor in it. there is one cpu that i put in.
´Dual core' just means that there are 2 separate cores in the CPU. Intel has made dual core pentuim 4, core duo and core 2 duo CPUs. ´Core 2 Duo´ is just one type of dual core CPU that Intel has made.
