Intel Core 2 Duo and Core 2 Extreme

Intel Core 2 Duo and Core 2 Extreme :

The Core 2 Duo and Core 2 Extreme are the first desktop processors to incorporate Intel’s Core Microarchitecture enhancements.They are fabricated using a 65nanometre manufacturing process, which Intel initially used to construct high-end Pentium D chips.Both processors are well equipped with 4MB of Level 2 (L2) cache and an effective front-side bus speed of 1,066MHz (actually 266MHz but data is transferred four times per clock cycle).

Smart Memory Access ensures that the location of data that the cores are working on is optimally placed in memory, thus reducing the effect of memory latency.

Core 2 Duo and Core 2 Extreme consists of intelligent power capability, Wide Dynamic Execution, Smart Memory Access, Advanced Smart Cache & Advanced Digital Media Boost.

Intelligent power capability :

A sophisticated control in the cores powers up individual logic systems when they’re needed this helps reduce the risk of processor failure.

Advanced Smart Cache :

Advanced Smart Cache is the mechanism by which L2 cache is shared between the two cores. The cache is shared and uncontrolled, meaning one core can be dynamically allocated up to 100% of it.
An advantage over independent cache for each core is that data need only be stored in one place if both cores are working on it.

Smart Memory Access :

Smart Memory Access ensures that the location of data that the cores are working on is optimally placed in memory, thus reducing the effect of memory latency.

Wide Dynamic Execution :

This encompasses the ability of each core to process four instructions at a time and the support for macrofusion, which involves combining commonly coupled processor instructions to save execution time.

Advanced Digital Media Boost :

Advanced Digital Media Boost sees a great improvement in the handling of 128-bit SSE (Streaming SIMD Extensions) instructions. These are now completed in a one clock cycle rather than split into two 64-bit calculations.

Intel's new microprocessor design has made chips more energy efficient than today's Pentium M processors, while offering even greater performance than previous x86 chips.

Core 2 Extreme chips are already ready to rumble the Core 2 Duo desktops and mobiles.
