Core 2 Duo models

Cássio Lima

In this tutorial we will list all of the Core 2 Duo, Core 2 Quad and Core 2 Extreme models to date and will introduce some of their key features.

Core 2 Duo processors (codenamed Conroe) started the new generation of Intel CPUs built on the new core architecture (because Core 2 Duo is the first processor for use by desktops). Using this architecture), and also the termination statement for Netburst architecture was used by Intel's 7th-generation microprocessors, an approximate generation since 2000. Due to the core architectures being built On the same architecture as the architecture used in Pentium M and Pentium III, we can say Core 2 Duo is the 6th generation of Intel CPUs. Besides Core 2 Duo, Core 2 Quad, Core 2 Extreme and Xeon series 5100 CPUs (codenamed Woodcrest) also use this new architecture.

Core 2 family has three products: Core 2 Duo - an alternative to Pentium 4 and Pentium D, Core 2 Quad - this product is a quad core Core 2 Duo and Core 2 Extreme - replacing Pentium Extreme Edition. The difference between Core 2 Duo and Core 2 Extreme is that the Core 2 Extreme processor runs at a higher clock rate and has an unlocked clock multiplier, which allows you to speed up (overclock) the CPU with How to change the CPU clock multiplier. Some Core 2 Extreme models have up to 4 CPU cores, for details see below.

Please note that you should not confuse Core 2 Duo with Core Duo. Core Duo is a commercial name for Pentium M manufactured in 65 nm technology with the code name Yonah, while Core 2 Duo is the commercial name of the CPU with the Merom codename (for laptop computers) or Conroe (for desktop computers). ), they use Intel's new core architecture.

The following is a summary of the main features of the Core 2 family:

1. Core architecture
2. L1 32KB instruction memory cache and L1 32KB data memory cache for each core.
3. Dual-core technology or quad-core technology.
4. 65 nm production process
5. Socket 775.
6. 800 MHz (200 MHz x 4), external clock speed of 1,066 MHz (266 MHz x 4) or 1,333 MHz (333 MHz x 4).
7. Unified memory cache L2 2 MB, 4 MB or 8 MAILBOX.
8. Intel virtual technology (except Core 2 Duo E4300)
9. Intel EM64T Technology.
10. SSE3 instruction set.
11. Execute Disable Bit
12. Ability to handle smart power consumption
13. Enhanced SpeedStep technology.

On Figure 1 you can see a picture of the Core 2 Duo CPU stand.

Now let's talk about the Core 2 Duo and Core 2 Extreme models that have been released until recently.
