Datasheet

In addition to supporting the existing Streaming SIMD Extensions 2 (SSE2) and 

Streaming SIMD Extensions 3 (SSE3), the processor supports Supplemental Streaming 

SIMD Extensions 3 (SSSE3) to speed up media algorithms like encoding and decoding. 

Advanced Dynamic Execution improves speculative execution and branch prediction 

internal to the processor. The floating point and multi-media units include 128-bit wide 

registers and a separate register for data movement. Streaming SIMD3 (SSE3) 

instructions provide highly efficient double-precision floating point, SIMD integer, and 

memory management operations. Also, these instructions enhance the performance of 

optimized applications for the digital home such as video, image processing and media 

compression technology. 

The processor features Enhanced Intel SpeedStep Technology, which enables real-time 

dynamic switching between multiple voltage and frequency points. The processor 

features the Auto Halt, Stop Grant, Deep Sleep, and Intel Enhanced Deeper Sleep C-

states. Enhanced thermal management capabilities are implemented including Intel® 

Thermal Monitor 1 and Intel Thermal Monitor 2 to provide efficient and effective cooling 

in high temperatures.

The Intel Core 2 Duo mobile processor utilizes socketable Micro Flip-Chip Pin Grid Array 

(Micro-FCPGA) and surface mount Micro Flip-Chip Ball Grid Array (Micro-FCBGA) 

package technology. The Micro-FCPGA package plugs into a 479-hole, surface-mount, 

Zero Insertion Force (ZIF) socket, which is referred to as the mPGA479M socket.

Intel Core 2 Duo mobile processor supports the Execute Disable Bit capability. This 

feature combined with a supporting operating system allows memory to be marked as 

executable or non executable. If code attempts to run in non-executable memory the 

processor raises an error to the operating system. This feature can prevent some 

classes of viruses or worms that exploit buffer overrun vulnerabilities and can thus help 

improve the overall security of the system. See the Intel® 64 and IA-32 Intel® 

Architectures Software Developer's Manual for more detailed information. 

Intel Virtualization Technology is a set of hardware enhancements to Intel server and 

client systems that combined with the appropriate software, will enable enhanced 

virtualization robustness and performance for both enterprise and consumer uses. Intel 

Virtualization Technology forms the foundation of Intel technologies focused on 

improved virtualization, safer computing, and system stability. For client systems, Intel 

Virtualization Technology’s hardware-based isolation helps provide the foundation for 

highly available and more secure client virtualization partitions.
