What is the difference between Dual Core, Core 2 Duo and Pentium D processors?

bsm allah alrahman alrahim

The comparison is like that :

What is the difference between Pentium D , Pentium Dual - core and Intel Core2 ?

and the answer will be like that :

All the above are called Brand Names For Intel Processor

- Pentium D and Pentium Dual-core contain2 cores ( and that what thay call it dual-core)

- under brand name Intel Core2 there is a processor called core2 due , this processor      contain2  processor (2 processor mean dual core)

Observe

  The package ( we said Processor but in reality it may contain1246 or more processor) we buy from the market can be solo core (1 proceesor in one package )  or dual core (2 processor in one package ) or Quad core (4 core in one package ) or6-core,8-core,10-core ...etc

Intel Core2 Duo processor: You'll experience revolutionary performance, unbelievable system responsiveness, and energy-efficiency second to none. And, you won't have to slow down for virus scan, multiple compute intensive programs, or multimedia downloads—these desktop processors are up to40 percent faster with improved energy-efficiency. Intel Dual-Core Technology: The Intel dual-core processor consists of two complete execution cores in one physical processor. Imagine that a dual-core processor is like a four-lane highway—it can handle up to twice as many cars as a two-lane road without making each car drive twice as fast. Similarly, with an Intel dual-core processor, you can do more at once than ever before, without slowing down: •Boost multitasking power with improved performance for highly multithreaded and compute-intensive applications •Reduce costs and use less power with energy-efficient Intel dual-core processors built on Intel® Core™ microarchitecture •Enjoy flexibility and the performance to handle robust content creation or intense gaming with multimedia-enabling technologies built in Intel Pentium D Processor: With an Intel Pentium D processor-based PC featuring two full processing cores, you get the flexibility and performance to handle multimedia entertainment, digital photo editing, even multiple users, simultaneously.
