Intel® Core™ Duo Processor
Power Efficient Computing
Power efficient compute platforms have
become increasingly important across all
client segments and form factors. Intel®
Core™ Duo Processor balances great
dual-core computing capabilities along with
power savings for battery life in notebooks
and voltage efficiency for cooler, less power
drawing systems. Traditional “mobile” and
“desktop” processors limit system design
options and foster compromises for the
end customer such as cooling fan noise,
battery life, performance and capabilities.
Intel Core Duo fosters a whole new
generation in computer product designs
from the world’s most innovative PC
manufacturers.
Specialized Dual-Core
Micro-architecture
The Intel® Core™ Duo Processor includes
two mobile-optimized execution cores in
a single processor that enable parallel
threads or applications to be executed
on separate cores with dedicated CPU
resources. This delivers outstanding
performance and responsiveness to
run multiple demanding applications
simultaneously and enhanced performance
on multi-threaded applications. The
Intel® Core™ Duo Processor also features
a high-performance core architecture that
uses techniques like micro-op fusion and
Advanced Stack Management to maximize
performance. Micro-op fusion combines
micro-ops derived from the same
macro-op. Advanced Stack Management
reduces the number of micro-ops in stack
related operations by tracking relative
stack pointer changes locally. Reduction
in number of micro-ops results in more
efficient scheduling and better performance
at lower power.
•Intel® Smart Cache
The Intel® Core™ Duo Processor features a shared 2MB
level-2 cache with Advanced Transfer Cache Architecture
and system bus between the two execution cores
delivering a smarter and more efficient cache & bus design
to enable enhanced Dual-Core performance & power
savings. Intel® Smart Cache enables active execution core
