What is core-------A standard processor has one core (Single-core). Single core processor only process one instruction at a time (They do use pipeline internally, which allow several instructions to be processed together, however they are still run one at a time.
What is a multi-Core Processor--------A multi-core processor is composed of two or more independent cores, each capable of processing individual instructions. A dual-core processor contain tow cores, a quad-core processor contains four cores, and a hexa-core processor contains six cores.
Core 2 Duo processors run two threads; i3′s and i5′s run four threads. Core 2 Duo processors are socket 775 (45/65nm); Core i3 and i5 processors are socket 1156 (nm) but only work with DDR3 RAM (Some Core 2 Duo’s work with both DDR2 and DDR3.)
For desktops, I’d stay clear of core 2 duos due to their lack of power; for laptops, it all depends on your usage. As laptops aren’t as easy to upgrade, buying dated technology might burn you in the future when you find your Core 2 Duo PC’s motherboard only supports 4GB RAM–for example.
i5′s come with “turbo boost”; however, i3′s overclock very well if that’s your thing. That’s where I’d put my money if you’re considering Core 2 Duo, i3, and i5: the i3 provides the best value for most casual PC users.
While I focused on i3, i5, and Core 2 Duo to answer a reader’s question, the principles apply when comparing i5, i7, and Core 2 Quad. I’d go for the i5 unless you are willing to pay a premium for a little more performance.

Why
do I Need Multiple Cores?
Multiple cores can be used to run
two programs side by side and, when an intensive program is running, (AV Scan,
Video conversion, CD ripping etc.) you can utilize another core to run your
browser to check your email etc.
Multiple cores really shine when
you’re using a program that can utilize more than one core (called
Parallelization) to improve the program’s efficiency. Programs such as graphic
software, games etc. can run multiple instructions at the same time and deliver
faster, smoother results.
So if you use CPU-intensive
software, multiple cores will likely provide a better experience when using
your PC. If you use your PC to check emails and watch the occasional video, you
really don’t need a multi-core processo
How many cores do i3, i5, and i7′s have?
- A Dual-core processor has two cores
- A Quad-core processor has four cores
- An i3 processor has two cores
- An i5 processor has two or four cores (depending on the model you have)
- An i7 processor has two, four, or six cores (depending on the model you have)
How Do Core 2 Duo and Core 2 Quad Compare with Core i3, i5, and i7?
If you’re looking for a good value PC and have decided on a Core 2 Duo, Core i3, or Core i5 (all best in value for casual computer use).Core 2 Duo processors run two threads; i3′s and i5′s run four threads. Core 2 Duo processors are socket 775 (45/65nm); Core i3 and i5 processors are socket 1156 (nm) but only work with DDR3 RAM (Some Core 2 Duo’s work with both DDR2 and DDR3.)
