Intel Core i7 Features

Product Overview
The leading-edge Intel Core i7 processor delivers unmatched technology for intelligent performance on the most demanding tasks, such as creating digital video and playing intense games.

Quad-Core Processing
Provides four complete execution cores in a single processor package. Four dedicated physical cores 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 Hyper-Threading Technology
Delivers two processing threads per physical core for a total of eight threads for massive computational throughput. With Intel HT Technology, highly threaded applications can get more work done in parallel, completing tasks sooner. With more threads available to the operating system, multitasking becomes even easier. This amazing processor can handle multiple applications working simultaneously, allowing you to do more with less wait time.

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 ultraefficient 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 i7 processor family 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.
