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.
Core 2 duo is dual core. And before that was core duo which was dual core too...
There is no difference between dual core and core 2 duo. Intel just name its recent family of dual core processors as "core 2 duo". Both (core 2 duo and dual core) works in same fashion.
About 200
the better processor is core 2 duo
the difference is core 2 duo gives more cooler temperature and supports more features than dual core processors
The difference is that Core Duo processors have to "engines" instead of one. With other words, Core Duo means 2 Intel processors in the same time working!
The main difference between the Intel Core 2 Duo blue stickers and the Intel Centrino Core 2 Duo pink stinkers is the wireless networking features. The Centrino offers more networking features than the non-Centrino.
There is little difference between Core 2 Core and Centrino Duo. Both are dual core processors but Core 2 is slightly better. Centrino is part of the Intel mobile platform.
The core 2 duo is faster.
There is no technological difference but the only difference should be how it is phrased
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.
´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.
