64 AND IA-32 ARCHITECTURES
2.1.11 The Intel
®
Core
™
Duo and Intel
®
Core
™
Solo Processors
(2006-Current)
The Intel Core Duo processor offers power-efficient, dual-core performance with a
low-power design that extends battery life. This family and the single-core Intel Core
Solo processor offer microarchitectural enhancements over Pentium M processor
family.
Its enhanced microarchitecture includes:
• Intel
®
Smart Cache which allows for efficient data sharing between two
processor cores
• Improved decoding and SIMD execution
• Intel
®
Dynamic Power Coordination and Enhanced Intel
®
Deeper Sleep to reduce
power consumption
• Intel
®
Advanced Thermal Manager which features digital thermal sensor
interfaces
• Support for power-optimized 667 MHz bus
The dual-core Intel Xeon processor LV is based on the same microarchitecture as
Intel Core Duo processor, and supports IA-32 architecture.

Core
™
2
Processor Family (2006-Current)
The Intel Xeon processor 5100 series, Intel Core 2 Extreme processor, and Intel Core
2 Duo processor family support Intel 64 architecture; and they are based on the
high-performance, power-efficient Intel
®
Core microarchitecture. The Intel Core
microarchitecture includes the following innovative features:
• Intel
®
Wide Dynamic Execution to increase performance and execution
throughput
• Intel
®
Intelligent Power Capability to reduce power consumption
• Intel
®
Advanced Smart Cache which allows for efficient data sharing between
two processor cores
• Intel
®
Smart Memory Access to increase data bandwidth and hide latency of
memory accesses
• Intel
®
Advanced Digital Media Boost which improves application performance
using multiple generations of Streaming SIMD extensions
