The Intel® Core™2 Duo mobile processor for Intel® Centrino® Duo mobile technology 

based on the Intel® 945 Express Chipset family is built on 65-nanometer process 

technology and is the next generation high-performance, low-power mobile processor 

based on the Intel® Core™ architecture.

All references to the word “processor” in this document are references to the Intel Core 

2 Duo mobile processor with 533- and 667-MHz front side bus (FSB), unless specified 

otherwise. 

The following list provides some of the key features on this processor:

• Dual-core processor for mobile with enhanced performance
• Intel® 64 architecture
• Supports Intel Architecture with Dynamic Execution
• On-die, primary 32-kB instruction cache and 32-kB write-back data cache per core
• On-die, up to 4-MB second level shared cache with Advanced Transfer Cache 

Architecture

• Data Prefetch Logic
• Streaming SIMD Extensions 2 (SSE2), Streaming SIMD Extensions 3 (SSE3) and 

Supplemental Streaming SIMD Extensions 3 (SSSE3) 

• 667-MHz, Source-Synchronous FSB for Standard Voltage processors
• Advanced Power Management features including Enhanced Intel SpeedStep® 

Technology 

• Intel® Enhanced Deeper Sleep state and Dynamic Cache Sizing
• Digital Thermal Sensor 
• Micro-FCPGA and Micro-FCBGA packaging technologies
• Intel® Virtualization Technology
• Execute Disable Bit support for enhanced security

64-bit computing on Intel architecture requires a computer system with a processor, 

chipset, BIOS, operating system, device drivers and applications enabled for Intel 64 

architecture. Processors will not operate (including 32-bit operation) without an Intel 

64 architecture-enabled BIOS. Performance will vary depending on your hardware and 

software configurations. Consult with your system vendor for more information.

The Intel Core 2 Duo mobile processor will be manufactured on Intel’s 65-nanometer 

process technology. The processor maintains support for MMX

TM

 technology, Streaming 

SIMD instructions, and full compatibility with IA-32 software. In addition, the Intel Core 

2 Duo mobile processor supports Intel 64 architecture which is enabled by 64-bit 

operating systems and consists of 64-bit instructions and registers. Further details on 

Intel Extended Memory 64 Technology and its programming model can be found in the 

Intel Extended Memory 64 Technology Software Developer’s Guide. The Intel Core 2 

Duo mobile processor features on-die, 32-kB level 1 instruction and data caches and 

features up to a 4-MB level 2 cache with Advanced Transfer Cache Architecture. The 

processor’s Data Prefetch Logic speculatively fetches data to the L2 cache before the L1 

cache requests occurs, resulting in reduced bus cycle penalties. The processor includes 

the Data Cache Unit Streamer which enhances the performance of the L2 prefetcher by 

requesting L1 warm-ups earlier. In addition, the Write Order Buffer depth is enhanced 

to help with the write-back latency performance.
