| 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.
1 Intel® 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.
2 Intel® 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.
3 Not 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.
4 Enabling 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.
5 The acoustic benefits of the 4-pin header are reliant on a properly designed motherboard. Contact your board manufacturer for compatibility.
