Features and Benefits of the Intel® Core™ i7 Processor Extreme Edition
Feature
Benefit
Quad-Core Processing
Provides four independent execution cores in one processor package. Four dedicated processing cores help
operating systems and applications deliver additional performance, so end users can experience better
multitasking and multithreaded performance across many types of applications and workloads.
Intel® Hyper-Threading
Technology
4
Delivers two processing threads per physical core for a total of eight threads for massive computational
throughput. With Intel® Hyper-Threading 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
3
Dynamically increases the processor’s frequency as needed by taking advantage of thermal and power head-
room 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.
Intel® QuickPath Interconnect
Intel’s latest system interconnect design increases bandwidth and lowers latency, while achieving data
transfer speeds as high as 25.6 GB/s.
Integrated Memory Controller
An integrated memory controller with three channels of DDR3 1066 MHz offers memory performance
up to 25.6 GB/s. Combined with the processor’s efficient prefetching algorithms, this memory controller’s
lower latency and higher memory bandwidth delivers amazing performance 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.
Digital Thermal Sensor (DTS)
Provides for more efficient processor and platform thermal control improving system acoustics. The DTS
continuously measures the temperature at each processing core. The ability to continuously measure and
detect variations in processor temperature enables system fans to spin only as fast as needed to cool the
system. The combination of these technologies can result in significantly lower noise emissions from the PC.
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
Improves system performance by optimizing the use of the available data bandwidth from the memory
subsystem and reducing the effective latency of memory accesses.
