The Intel

®

 Core™2 Duo processor E8000 and E7000 series are based on the Enhanced Intel

®

 Core™ 

microarchitecture. The Enhanced Intel

®

 Core™ microarchitecture combines the performance across 

applications and usages where end-users can truly appreciate and experience the performance. These 

applications include Internet audio and streaming video, image processing, video content creation, 

speech, 3D, CAD, games, multimedia, and multitasking user environments.
Intel

®

 64

Φ

 architecture enables the processor to execute operating systems and applications written 

to take advantage of the Intel 64 architecture. The processor, supporting Enhanced Intel Speedstep

®

 

technology, allows tradeoffs to be made between performance and power consumption.
The Intel Core™2 Duo processor E8000 and E7000 series also includes the Execute Disable Bit 

capability. This feature, combined with a supported operating system, allows memory to be marked 

as executable or non-executable.

Virtualization Technology provides silicon-based functionality that works together with compatible 

Virtual Machine Monitor (VMM) software to improve on software-only solutions. 

The Intel

®

 Trusted Execution Technology (Intel TXT) is a key element in Intel's safer computing 

initiative that defines a set of hardware enhancements that interoperate with an Intel TXT enabled 

operating system to help protect against software-based attacks. It creates a hardware foundation 

that builds on Intel's Virtualization Technology to help protect the confidentiality and integrity of data 

stored/created on the client PC.
