Product information
Features and benefits
| Dual-core processing | Two independent processor cores in one physical package run at the same frequency; 512 KB of shared L2 cache and 800 MHz Front Side Bus. |
| 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. |
| 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 and photo processing, 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. |
| Intel® 64F | An enhancement to Intel’s 32-bit architecture to enable 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 can allow the use of extended virtual and physical memory. |
| Execute Disable Bit2 | 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. |
| Intel designed thermal solution for boxed processors | Intel boxed processors ship with a thermal solution specifically for this processor designed for maximum thermal and acoustic performance. |
1Intel 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.
F Intel® 64 Architecture requires 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.
2 Enabling Execute Disable Bit functionality requires a PC with a processor with Execute Disable Bit capability and a supporting operating system. Check with your PC manufacturer on whether your system delivers Execute Disable Bit functionality.
