Detailed Features Features Quad-Core Processing Provides four independent execution cores in a single processor package. Four dedicated processing threads help operating systems and applications deliver additional performance, so end users can experience better multitasking and multi-threaded performance across many types of applications and workloads. Chipset Support Intel® Express Chipsets offer an array of exciting capabilities including dual graphics and deliver an impressivelevel of performance for demanding users. Other third-party chipsets may support Intel Core 2 Extreme quad-core processors; contact your board manufacturer for compatibility. 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® HD 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, 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.
