The short answer is that the i3 is in fact a dual core processor, but with more features than the previous generation of dual core processors (Intel Core Duo.)
The Intel i3 processor has a faster bus speed and more cache memory than an Intel Core Duo processor. It also has integrated graphics.
For those of you building your own computer, you can buy an i3 processor and a motherboard with an integrated HDMI output. This means that you don't have to buy your own video card.
Caveat: In the i3/i5/i7 line of processors, if you get a quad-core processor (like the i5-760) the trade-off is that it does not have the integrated graphics, and so you should not get a motherboard that has the on-board video outputs.

I rightly enjoy this answer above, but would like to add that all i3, i5, and i7 Intel processers possess integrated graphics solutions after Lynnfield. This means Sandy Bridge, Ivy Bridge, and Haswell. This means if the i3, i5, or i7 has a 4 digit number instead of 3 digit number for reference, it will support integrated graphics. An i5-760 has no integrated video, but an i5-2500k does.
Core 2 Duo uses a different socket than all iterations of the i3 processor, which is important to note if a consumer is interest in upgrading / changing from Duo to i3.
They're from different processor families, Pentium processors are generally used in vintage computers as they are power hungry and slow
difference between dual core and core i3
i3 is a dual core. The i7 model is a quad core processor.
Quad core comes after dual core. Although Intel has a new range called i3, i5 and i7.
This depends on what type of A-Series you are talking about, but the i3 is better than the Pentium Dual Core although they are based on the same microarchitecture.
Intel Core i3-380M is better because it processes at 2.53 GHz while the i3-2350M processes at 2.3 GHz but that is a very small difference between the two that you probably couldn't really tell the difference.
There might be a slight improvement in an i3, but it is unlikely you will notice the difference. i3 is basically dual core, just with a few supposed improvements. It might be able to run Internet-reliant programs a little faster, making the internet seem faster, but such an improvement will probably be negligible. What will really make the difference in this case is the network card.
The Core i3 is a low-end processor line made by Intel. Some specifications are listed below: Core i3-530 - 2.93 GHz dual-core, priced at $113 Core i3-540 - 3.07 GHz dual-core, priced at $117 Core i3-550 - 3.20 GHz dual-core, priced at $138 Core i3-560 - 3.33 GHz dual-core, priced at $138 All of these processors are available on Intel's LGA-1156 socket, and are on the low end of Intel's Core lineup. AMD makes a comparable, but much less expensive, line of dual-core processors called the Athlon II X2 series.
Intel Core i3 is faster even though they are both dual core processors. The i3 has multi-threading capability which lets it run two processes on one core versus one process per core the the Intel Core 2 duo. Bottom line: Intel core i3 is faster.
Two physical cores and two virtual cores.
IS ACER CORE I3 BETTER HP CORE 13 BETTER, what is the difference in price as well as performance
Core i3 is a CPU with the newest Intel architecture. It is performing much better in tests compared with the core 2 duo. Nowadays the GHz are not so important anymore, it is the architecture.
2nd generation i3 was developed in 2nd Generation and 3rd Generation are developed in 3rd Generation..... :) lol
