Introduction

Intel has finally launched a successor for Pentium 4. Its name is Core 2 Duo and it is the first desktop CPU to use the new Core microarchitecture. In this tutorial we will list all Core 2 Duo, Core 2 Quad and Core 2 Extreme models released so far and will talk about their main features.

Core 2 Duo processor (codenamed Conroe) starts a new CPU generation from Intel based on the new Core microarchitecture (as Core 2 Duo is the first desktop processor to use this microarchitecture) and declares the end of Netburst microarchitecture used by Intel’s 7th generation processors, which is around since 2000. As Core microarchitecture is based on the same architecture used by Pentium M and Pentium III, we can say that Core 2 Duo is a 6th generation Intel CPU. Besides Core 2 Duo, Core 2 Quad, Core 2 Extreme and Xeon series 5100 (codenamed Woodcrest) use this new microarchitecture.

Core 2 family comes in three flavors: Core 2 Duo, which replaces Pentium 4 and Pentium D, Core 2 Quad, which is a quad-core Core 2 Duo, and Core 2 Extreme, which replaces Pentium Extreme Edition. The difference between Core 2 Duo and Core 2 Extreme is that the last one runs at higher clock rates and has its clock multiplier unlocked, which allows you to overclock the CPU by changing the CPU clock multiplier. Some Core 2 Extreme models have four CPU cores, as you will see on the next page.
 
Pay attention to not confuse Core 2 Duo with Core Duo. Core Duo is the commercial name for a Pentium M manufactured using 65 nm process, codenamed Yonah, while Core 2 Duo is the commercial name for the CPU codenamed Merom (for laptops) or Conroe (for desktops), which uses the new Intel Core microarchitecture. For an in-depth discussion on this new microarchitecture, read our Inside Intel Core Microarchitecture tutorial.

Here is a summary of the main Core 2 family features:
