Core 2 Duo

Targets: Computers & Peripherals, General Purpose, Imaging & Video, Industrial, Medical, Military & Aerospace, Security

The Core 2 Duo targets performance intensive, low-power embedded applications in smaller form factors such as interactive clients (point-of-sale terminals and ATMs), gaming platforms, industrial control and automation, digital security surveillance and medical imaging. While incorporating advanced processor technology, these processors remain software-compatible with previous IA-32 processors.

Based on 45nm process technology, the Intel Core 2 Duo processor E8400 uses hafnium-infused Hi-k transistors, increasing processor performance by doubling the transistor density, improving efficiency and speed relative to the previous generation, and increasing cache size up to 6-Mbytes – a three-fold increase compared to the Intel Core 2 Duo processor E6400. It is validated with the Intel Q35 Express chipset. Based on 65nm process technology, the Intel Core 2 Duo processors E6400 and E4300 are also validated with the Intel Q35 Express chipset. They are validated with the Intel Q965 Express chipset, which includes an optimized memory engine for exceptional system performance and specialized technologies for enhanced graphics, sound and manageability.

The Intel Core Microarchitecture includes wide dynamic execution that allows each core to simultaneously complete up to four full instructions per clock cycle. Intel Advanced Smart Cache reduces memory latency to frequently used data through dynamic allocation of shared L2 cache. Intel Smart Memory Access accelerates out-of-order execution, reduces time in-flight instructions must wait for data, and moves data from system memory into fast L2 cache prior to execution.

Intel Advanced Digital Media Boost accelerates execution of Streaming SIMD Extension (SSE) instructions to improve performance of video, audio, and image processing for multimedia, encryption, financial, engineering, and scientific applications. 128-bit SSE instructions, issued at a throughput rate of one per clock cycle, effectively doubles speed of execution over previous-generation processors. 45nm versions include new Super Shuffle Engine to improve existing SSE instructions while enabling significant gains on the latest SSE4 instruction set.

Intel Virtualization Technology allows one hardware platform to function as multiple "virtual" platforms and provides greater isolation and security between different applications and operating systems for added protection. Intel 64 Architecture supports 64-bit instructions, providing flexibility for 64-bit and 32-bit applications and operating systems. Intel Trusted Execution Technology (Intel TXT) defends against software-based attacks and helps protect confidentiality and integrity of data stored or created on the system. Enables each application to run within its own space, protected from all other software on the system. Execute Disable Bit3 marks memory regions as executable or non-executable when combined with a supporting operating system. Digital Thermal Sensor (DTS) enables efficient processor and platform thermal control. Thermal sensors located within the processor measure maximum temperature on the die at any given time.
