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 Front Side Bus, for truly parallel computing.

Intel® Wide Dynamic Execution

Improves execution speed and efficiency, delivering more instructions per clock cycle. Each core can 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 prediction mechanism reduces the time in-flight instructions have to wait for data. 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 efficient methods of loading and storing data in main memory.

Intel® Advanced Smart Cache

Dynamically allocates the shared L2 cache to each processor core based on workload. This efficient, dual-core-optimized implementation increases the probability that each core can access data from fast L2 cache, significantly reducing latency to frequently used data and improving performance.

Intel® Advanced Digital Media Boost

Accelerates the execution of Streaming SIMD Extension (SSE) instructions to significantly improve the performance on a broad range of multimedia and compute intensive 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 Shuffle Engine, which improves existing SSE instructions while enabling significant gains on the latest SSE4 instruction set. SSE4-optimized applications, such as video editing and encoding in high-definition resolution, will see additional performance improvements.

Intel® Virtualization Technology (Intel® VT)

Allows one hardware platform to function as multiple “virtual” platforms. Intel VT improves manageability, Technology (Intel® VT)3 limits downtime, and maintains worker productivity by isolating computing activities into separate partitions.

Intel® 64 Architecture

Allows the processor to access larger amounts of memory. With appropriate 64-bit 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|

Provides enhanced virus protection when deployed with a supported operating system and prevents the code from infecting the system. Memory can 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.

Intel Designed Thermal Solution for Boxed Processors

Includes a 4-pin connector for fan speed control to help minimize the acoustic noise levels generated from running the fan at higher speeds for thermal performance.5 Fan speed control technology is based on actual CPU temperature and power usage.
