Intel® Core™2 Duo Desktop Processor
New version now available based on Intel’s 45nm technology
Product Brief
Intel® Core™2 Duo  
Desktop Processor
Product Description
The Intel® Core™2 Duo processor was developed to meet 
the insatiable demand for increased performance from  
PC users running multiple intense 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 new 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 new 
Intel Core 2 Duo processors deliver more performance 
without using more energy.
Built on the innovative Intel® Core™ microarchitecture, the 
Intel Core 2 Duo desktop processor delivers revolutionary 
dual-core performance and breakthrough processor  
energy efficiency. With Intel® Wide Dynamic Execution, 
Intel® Smart Memory Access, Intel® Advanced Smart 
Cache, and Intel® Digital Media Boost, this new processor 
is designed to do more in less time. Additional features, 
which support enhanced security, virtualization, and  
64-bit computing, make the Intel Core 2 Duo the most  
impressive processor developed for an increasingly  
multimedia-centered, high-definition world.
Energy Efficiency
Design changes in the Intel Core 2 Duo processors that 
improve performance also increase processor energy effi-
ciency by operating at lower frequencies that require less 
power to run. Intel® Intelligent Power Capability, a feature 
that optimizes energy usage of the processor cores, turns on 
computing functions only when needed. These more energy- 
efficient processors support smaller, more capable, and  
quieter desktop PCs to conserve critical power resources.
