The Intel Core 2 Duo processor was developed to meet the insatiable demand for increased performance from PC users running multiple software applications simultaneously. In the office, PC usage has changed from data entry and word processing to e-commerce, online collaboration, and an ever-increasing need for continual security and virus protection. In the home, interests have shifted from low-bandwidth photos and Internet surfing to downloading and viewing high-definition videos, as well as advanced photo and video editing.
Intel's 45nm manufacturing technology, with hafnium infused hi-k transistors, enables 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. These Intel Core 2 Duo processors deliver more performance without using more energy.
Intel 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 MHz4 front side bus, for truly parallel computing.
Intel wide dynamic execution
Improve execution speed and efficiency, delivering more instructions per clock cycle. Each core can complete up to four full instructions simultaneously.
Intel smart memory access
Optimize 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. 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 smart cache
The shared L2 cache1 is dynamically allocated to each processor core based on workload. This efficient 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 digital media boost
Accelerate the execution of Streaming SIMD Extension (SSE) instructions to significantly improve the performance on a broad range of applications, including video, audio, and 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.
Intel virtualization technology
Allow one hardware platform to function as multiple "virtual" platforms. Intel VT improves manageability, limiting downtime and maintaining worker productivity by isolating computing activities into separate partitions.
Intel 64 architecture
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 architecture can allow the use of extended virtual and physical memory.
Execute disable bit
Provides extended virus defense when deployed with a supported operating system. Memory can 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. This can prevent the code from infecting the system.
Intel-designed thermal solution for boxed processors
Include 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. Fan speed control technology is based on actual processor temperature and power usage.
