As the name suggests... four. Two on each of two dies.
in nanometers what is the current size of a quad-core processor
The quad core processor is a processing unit for computers. The main type of computer that a quad core processor runs on and is used on is a Dell computer.
It is a type of processor, therefore it is hardware. I recommend the i7 processor, which is a quad core
i3 is a dual core. The i7 model is a quad core processor.
Core 2 Quad
The quad core processor has four cores. It is essentially two of the Core 2 Duo processors as the Core 2 Duo only has two. The quad core will be faster and as a result more expensive.
Applications which have been designed to take advantage of mult-core processors will run about twice as fast on a quad core processor as compared to a dual core processor.

This particular model cannot be upgraded to a quad-core processor. However, Sony does provide VAIO models containing quad-core processors.
Dual core 2 is the 2nd version of the dual core processor and quad core is obviously 4 cores in a processor.
Four independent cores into a single package composed of a single IC. A dual-core processor contains two cores, and a quad-core processor contains four cores.
The question you're asking, unfortunately, is not worded correctly. An Intel processor is a family of processor, where a quad-core processor is a type of processor. The Intel family includes many types of quad-core processors. However, to try and disambiguate what you're asking, an Intel core processor will be good, no matter what type it is. An Intel quad-core processor - for example, the Intel i7 - will perform fantastically well. The other main type of processor manufacturer - AMD - also have quad-core processors. However, a lot of it is down to opinion and machine build as to whether Intel is better than AMD, but personally, I believe Intel will out-perform and out-last an AMD processor.
