Intel Lynnfield LGA1156

Intel Core microarchitecture is Intel's latest generation of dynamically scalable microarchitecture. The Intel Core i5 processor is based on the same energy-efficient processor core as the Intel Core i7 processor, but is designed for mainstream computing.

Formerly codenamed "Lynnfield," the new Intel Core i5/i7 chips are based on Intel's Nehalem microarchitecture and are designed for mainstream consumers. All LGA1156-socket processors are lead- and halogen-free and feature Intel's exclusive Turbo Boost Technology. Intel Core i7 processors also support Intel Hyper-Threading Technology, which duplicates cores and thereby turns a four-core processor into a virtual eight-core unit.

The new Core i7 and i5 processors are the first Intel processors to integrate both a 16-lane PCI Express 2.0 graphics port and two-channel memory controller, enabling all input/output and manageability functions to be handled by the single-chip Intel P55 Express Chipset. A new Direct Media Interface (DMI) connects between the processor and chipset.

Intel Core i5 Features

Quad-Core Processing
Provides four complete execution cores in a single processor package. Four dedicated physical threads help operating systems and applications deliver additional performance, so users can experience better multitasking and multithreaded performance across many types of applications and workloads.

Intel Turbo Boost Technology
Dynamically increases the processor's frequency as needed by taking advantage of thermal and power headroom when operating below specified limits. Get more performance automatically, when you need it the most.

8 MB Intel Smart Cache
This large last-level cache enables dynamic and efficient allocation of shared cache to all four cores to match the needs of various applications for ultra-efficient data storage and manipulation.

Integrated Memory Controller
An integrated memory controller offers stunning memory read/write performance through efficient prefetching algorithms, lower latency, and higher memory bandwidth making the Intel Core i5 processor ideal for data intensive applications.

Intel HD Boost
Includes the full SSE4 instruction set, significantly improving a broad range of multimedia and compute-intensive applications. The 128-bit SSE instructions are issued at a throughput rate of one per clock cycle, allowing a new level of processing efficiency with SSE4-optimized applications.
