Features:
-
Six Core/12 Thread Processing -- Provides six complete execution cores in a single processor package, delivering 12 computing threads to help operating systems and applications deliver additional performance, so users can experience better multitasking and multi-threaded performance across many types of applications and workloads.
-
Massive PCIe Graphics Bandwidth -- Provides up to 40 lanes of PCIe bandwidth for PCI Express* devices, which can include graphics cards, storage controllers, and additional LAN devices. This processor has more than 2X the PCIe lanes vs. other 2nd Generation Intel Core desktop processors.
-
Four Channel Integrated Memory Controller -- An integrated memory controller with four channels of DDR3 1600 MHz offers memory bandwidth up to 51.2 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® Hyper-Threading Technology -- Delivers two processing threads per physical core for a total of 12 threads for massive computational throughput, allowing highly threaded applications to get more work done faster.
-
Intel® Turbo Boost Technology 2.01 -- 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.
-
Intel® Smart Cache -- This large last-level cache enables dynamic and efficient allocation of shared cache to all six cores to match the needs of various applications for ultra-efficient data storage and manipulation.
-
Intel AVX -- Processor instructions that significantly improve floating point performance.
-
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.
