Intel® Core™2 Duo Processor

Built on the innovative Intel® Core™ microarchitecture, the Intel® Core™2 Duo desktop processor delivers revolutionary dual-core performance and breakthrough processor 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. These more energy efficient processors support smaller, more capable, and quieter desktop PCs to conserve critical power resources.

The latest versions built on Intel® 45nm manufacturing technology take these benefits to a whole new level. This technology uses hafnium-infused Hi-k transistors, enabling even more processor performance by doubling the transistor density, improving efficiency and speed relative to the previous generation, and increasing cache size by up to 50 percent. Intel 45nm manufacturing technology helps the Intel Core 2 Duo processor deliver even more performance without using more energy. This dual-core processor represents Intel’s continued leadership and drive of multi-core processing.

Features and Benefits of the Intel® Core™2 Duo Desktop Processor
Features	Benefits
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.
Intel® Wide Dynamic Execution	Improves execution speed and efficiency, delivering more instructions per clock cycle.
Intel® Smart Memory Access	Improves system performance by optimizing the use of the available data bandwidth.
Intel® Advanced Smart Cache	Optimized for multi-core processors, providing heigher performance with a more efficient cache subsystem.
Intel® Advanced Digital Media Boost	Accelerates a broad range of multimedia, encryption, scientific and financial applications by significantly improving performance when executing Intel® Streaming SIMD Extension (SSE/SSE2/SSE3) instructions. Intel® HD Boost implemented on 45nm processors offers new Intel® Streaming SIMD Extension 4 (Intel SSE4) instructions for even greater multimedia performance and faster high definition video editing and encoding.
Intel® Virtualization Technology (Intel® VT)^2,3	Intel® VT allows one hardware platform to function as multiple “virtual” platforms.
Intel® Trusted Execution Technology (Intel® TXT)^2,3	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.
Intel® 64 architecture	Enables the processor to access larger amounts of memory.
Execute Disable Bit⁴	Provides enhanced virus protection when deployed with a supported operating system.
Intel® designed thermal solution for boxed processors	Includes a 4-pin connector for fan speed control to help minimize the acoustic noise levels generated from running the fan at higher speeds for thermal performance.⁵

°Intel processor numbers are not a measure of performance. Processor numbers differentiate features within each processor family, not across different processor families. See www.intel.com/products/processor_number/ for details.
¹Intel® Core™2 Duo processors support an 800 MHz, 1066 MHz, or 1333 MHz system bus. For information on a specific processor, see the Processor Spec Finder at http://processorfinder.intel.com or contact your Intel representative for more information.
²Intel® Virtualization Technology (Intel® VT), Intel® Trusted Execution Technology (Intel® TXT), and Intel® 64 architecture require a computer system with a processor, chipset, BIOS, enabling software and/or operating system, device drivers and applications designed for these features. Performance will vary depending on your configuration. Contact your vendor for more information.
³Not all specified units of this processor support Intel® VT or Intel® TXT. See the Processor Spec Finder at http://processorfinder.intel.com or contact your Intel representative for more information.
⁴Enabling Execute Disable Bit functionality requires a computer system with a processor with Execute Disable Bit capability and a supporting operating system. Check with your vendor on whether your system delivers Execute Disable Bit functionality.
⁵The acoustic benefits of the 4-pin header are reliant on a properly designed motherboard. Contact your board manufacturer for compatibility.
