Features and Benets of the Intel® Core™2 Duo Desktop Processor
Features Benets
Dual-Core Processing Two independent processor cores in one physical package run at the same frequency, and share up to
6 MB of L2 cache as well as up to a 1333 MHz
1
Front Side Bus, for truly parallel computing.
Intel® Wide Dynamic Improves execution speed and efciency, delivering more instructions per clock cycle. Each core can
Execution complete up to four full instructions simultaneously.
Intel® Smart Memory Access Optimizes the use of the data bandwidth from the memory subsystem to accelerate out-of-order execution.
A newly designed prediction mechanism reduces the time in-ight instructions have to wait for data. New
pre-fetch algorithms move data from system memory into fast L2 cache in advance of execution. These
functions keep the pipeline full, improving instruction throughput and performance. 45nm versions further
improve this feature, with more efcient methods of loading and storing data in main memory.
Intel® Advanced Smart Cache The shared L2 cache is dynamically allocated to each processor core based on workload. This efcient,
dual-core optimized implementation increases the probability that each core can access data from fast
L2 cache, signicantly reducing latency to frequently used data and improving performance.
Intel® Advanced Digital Accelerates the execution of Streaming SIMD Extension (SSE) instructions to signicantly improve the
performance on a broad range of applications, including video, audio, and image processing, and multimedia,
encryption, nancial, engineering, and scientic applications. The 128-bit SSE instructions are now issued at a
throughput rate of one per clock cycle effectively doubling their speed of execution on a per clock basis over
previous generation processors. 45nm versions include a new Super Shufe Engine, which improves existing
SSE instructions while enabling signicant gains on the latest SSE4 instruction set. SSE4-optimized applications,
such as video editing and encoding in high-denition resolution, will see additional performance improvements.
Intel® Virtualization Intel® VT allows one hardware platform to function as multiple “virtual” platforms. For businesses, Intel VT
Technology (Intel® VT)
2/3
offers improved manageability, limiting downtime and maintaining worker productivity by isolating
computing activities into separate partitions.
Intel® Trusted Execution Intel® TXT provides hardware-based mechanisms to help protect against software-based attacks and
Technology (Intel® TXT)
2/3
help protect the condentiality and integrity of data stored or created on the system. It does this by
enabling a trusted environment where applications can run within their own space, protected from all
other software on the system.
Intel® 64
2
Architecture Enables the processor to access larger amounts of memory. With appropriate 64-bit supporting hardware
and software, platforms based on an Intel processor supporting Intel 64 architecture can allow the use of
extended virtual and physical memory.
Execute Disable Bit
4
Provides enhanced virus protection when deployed with a supported operating system. The Execute
Disable Bit allows memory to be marked as executable or non-executable, allowing the processor to raise
an error to the operating system if malicious code attempts to run in non-executable memory, thereby
preventing the code from infecting the system.
Intel Designed Thermal Includes a 4-pin connector for fan speed control to help minimize the acoustic noise levels generated
Solution for Boxed from running the fan at higher speeds for thermal performance.
5
Fan speed control technology is based
Processors on actual CPU temperature and power usage.
Better Acoustics
Intel Core 2 Duo processors are equipped with a Digital
Thermal Sensor (DTS) that enables efcient processor and
platform thermal control. Thermal sensors located within the
processor measure the maximum temperature on the die at
any given time. Intel® Quiet System Technology, included in
the Intel® Express Chipset families
6
, uses the DTS to regulate
the system and processor fan speeds. The acoustic benet
of temperature monitoring is that system fans spin only as
fast as needed to cool the system, and slower spinning fans
generate less noise.
