Intel Core 2 Duo E8500 Processor BX80570E8500
Built on the innovative Intel® Core™ microarchitecture, the Intel Core 2 Duo desktop processor delivers revolutionary dual-core performance and breakthrough processor energy efficiency. With Intel® Wide Dynamic Execution, Intel® Smart Memory Access, Intel® Advanced Smart Cache, and Intel® Digital Media Boost, this new processor is designed to do more in less time. Additional features, which support enhanced security, virtualization, and 64-bit computing, make the Intel Core 2 Duo the most impressive processor developed for an increasingly multimedia-centered, high-definition world.
Energy Efficiency
Design changes in the Intel Core 2 Duo processors that improve performance also increase processor energy efficiency by operating at lower frequencies that require less power to run. Intel® Intelligent Power Capability, a feature that optimizes energy usage of the processor cores, turns on computing functions only when needed. These more energy efficient processors support smaller, more capable, and quieter desktop PCs to conserve critical power resources.
By offering a single brand name for our mainstream desktop and laptop dual-core processors, Intel’s branding strategy makes it simple for consumers and businesses to choose a powerful and energy efficient processor – and makes it easier for developers to “write once, run everywhere.”
“…and not only was the Intel system running at 2.66GHz - a slower clock rate then the top Pentium 4 - it was outpacing an overclocked Athlon 64 FX-60. Wrap your brain around that idea for a bit” - Intel Reveals Conroe Architecture: Lloyd Case, Extremetech March 8,2006
Intel® Core™2 Processor Family
When launched later this year, the Intel® Core™2 Duo processor will provide enhanced performance and energy-efficiency in mobile applications while bringing for the first time the benefits of energy-efficient performance to mainstream desktop computing. It will be Intel’s highest performing desktop processor ever and the new first choice of gamers and multimedia professionals worldwide.
As with the Intel® Pentium® processor brand, use of the number “2″ signals the arrival of the next generation of technology to the Intel® Core™ processor line. In order to be consistent with our current Intel Core processor naming, we are continuing to use “Duo” to creatively and effectively indicate Intel® dual-core technology.

Features
- Dual-Core Processing
Two independent processor cores in one physical package run at the same frequency, and share up to 6 MB of L2 cache as well as up to a 1333 MHz1 Front Side Bus, for truly parallel computing.
Intel® Wide Dynamic Execution
Improves execution speed and efficiency, delivering more instructions per clock cycle. Each core can complete up to four full instructions simultaneously. - Intel® Smart Memory Access
Optimizes the use of the data bandwidth from the memory subsystem to accelerate out-of-order execution. A newly designed prediction mechanism reduces the time in-flight instructions have to wait for data. New pre-fetch algorithms move data from system memory into fast L2 cache in advance of execution. These functions keep the pipeline full, improving instruction throughput and performance. 45nm versions further improve this feature, with more efficient methods of loading and storing data in main memory. - Intel® Advanced Smart Cache
The shared L2 cache is dynamically allocated to each processor core based on workload. This efficient, dual-core optimized implementation increases the probability that each core can access data from fast L2 cache, significantly reducing latency to frequently used data and improving performance. - Intel® Advanced Digital Media Boost
Accelerates the execution of Streaming SIMD Extension (SSE) instructions to significantly improve the performance on a broad range of applications, including video, audio, image processing and multimedia, encryption, financial, engineering and scientific applications. The 128-bit SSE instructions are now issued at a throughput rate of one per clock cycle effectively doubling their speed of execution on a per clock basis over previous generation processors. 45nm versions include a new Super SHuffle Engine, which improves existing SSE instructions while enabling significant gains on the latest SSE4 instruction set. SSE4-optimized applications, such as video editing and encoding in high-definition resolution, will see additional performance improvements. - Intel® Advanced Digital

Intel® VT allows one hardware platform to function as multiple “virtual” platforms. For businesses, Intel VT offers improved manageability, limiting downtime and maintaining worker productivity by isolating computing activities into separate partitions - Intel® Trusted Execution Technology (Intel® TXT)
Intel® TXT provides hardware-based mechanisms to help protect against software-based attacks and help protect the confidentiality and integrity of data stored or created on the system. It does this by enabling a trusted environment where applications can run within their own space, protected from all other software on the system. - Intel® 64 Architecture
Enables the processor to access larger amounts of memory. With appropriate 64-bit supporting hardware and software, platforms based on an Intel processor supporting Intel 64 architecture can allow the use of extended virtual and physical memory. - Execute Disable Bit
Provides enhanced virus protection when deployed with a supported operating system. The Execute Disable Bit allows memory to be marked as executable or non-executable, allowing the processor to raise an error to the operating system if malicious code attempts to run in non-executable memory, thereby preventing the code from infecting the system.
