Intel Core 2 Duo E6600, 2.4 GHz (BX80557E6600) Processor

The Intel® Core™2 E6600 desktop processor combine the performance of the previous generation of desktop products with the power efficiencies of a low-power microarchitecture to enable smaller, quieter systems. The certain processor is 64-bit processor that maintains compatibility with IA-32 software.
This processor supports several Advanced Technologies including the Execute Disable Bit, Intel® 64 Architecture, and Enhanced Intel SpeedStep® Technology and supports Intel® Virtualization Technology (Intel VT). With this Intel® Core™2 Duo desktop processor, you'll experience revolutionary performance, unbelievable system responsiveness, and energy-efficiency built in – up to 40% faster and over 40% more energy efficient. Intel® Core™2 Duo processors are the new brand name for next-generation energy-efficient performance desktop and mobile processors.
The Intel® Core™2 processors for desktop and mobile computers are based on the Intel® Core™ microarchitecture, Intel's new industry-leading foundation for all mobile, desktop and server platforms moving forward. Compared to Pentium 4, Core Duo (not to be confused with Core 2 Duo) offers low power consumption, low waste heat and high performance per clock. This is almost an exact opposite to the Pentium 4 which used so much power that the ATX specification had to be modified to add more 12V rails, and produced so much heat that they often throttled and made reaching 4GHz almost impossible. Not only this, but clock for clock performance wasn't stellar – hence the need for higher clock speeds in the first place.
Core 2 Duo is the next generation on from Core Duo. If it wasn't completely obvious, the "Duo" portion of the name indicates that these Core 2 Duo are dual-core processors. Unlike previous Pentium D processors, these use a shared Level 2 cache (2MB or 4MB depending on the processor). This can be dynamically allocated depending on the task being run. For instance, if running an application that isn't multi-threaded (i.e. can't take advantage of a second core), then the primary core would get the full 4MB of Level 2 cache. Having more Level 2 cache means that fewer requests need to be made to the system memory – one of the biggest causes of latency. So this makes E6600 one of the most powerful processors ever made introducing low latency and low power consumption. When idling, the Core 2 Duo E6600 will drop its multiplier from 9.0x (2.4 GHz) to 6.0x (1.6 GHz) to conserve power. With these power saving modes enabled, Core 2 Duo system conservs 17W of power (for example 186W to 169W) and rans about 5°F cooler than when power saving mode is disabled. This isn't much of a difference, really, as the "Conroe" architecture already is fairly efficient in terms of power consumption and heat production.
In order to show the superiority of Core 2 Duo E6600, a CPU arithmetic test (SiSoft Sandra 2007) was conducted involving several processors. See carefully the results:

Core 2 Duo E6600 (3.0 GHz)* --> 27690 !!!!
Core 2 Duo E6600 (2.4 GHz) --> 22137 !!!!
Core 2 Duo E6400 (2.13 GHz) --> 19738
Athlon64 FX-62 (3.0 GHz)* --> 21873
Athlon64 FX-62 (2.8 GHz) --> 20382
Athlon64 X2 4600+ (2.4 GHz) --> 17495
Athlon64 X2 4200+ (2.2 GHz) --> 15994
Athlon64 X2 3800+ (2.0 GHz) --> 14515
