Processors Built For What You Want To Do

2nd Generation Intel® Core™ Processors in the LGA2011 Socket

If you are looking for pure, raw, adrenalinepumping power, then the 2nd gen Intel® Core™ processors in the LGA2011 socket are for you. These processors provide you with the most cores, I/O options, memory channels, and raw computing power of any Intel® desktop processor. These are not the processors of the past. Lay waste to everything in your path in whatever game you choose to dominate in, or dive into the world of multimedia editing like a modern-day Picasso. Combining a 2nd gen Intel Core processor with one, two, three, or even four discrete video cards and up to 64 GB of memory across four channels gives you heart-stopping performance no matter what application you choose. If a super-smart, ultra-threaded, absolutely uncompromised processor is on your wish list, then your search is over.

Boost Your Performance
The 2nd gen Intel Core processor family delivers a great PC experience. Whether you are looking for improved performance, greater adaptability, or differentiated visual features, Intel has the processor to fit your needs. If you are using your PC for creativity, playing games, or everyday tasks such as homework and e-mail, these new processors make it easier to design, render, edit, play, and share.

The 2nd gen Intel Core processors feature Intel® Turbo Boost Technology 2.0¹, which delivers a burst of processor speed automatically when the workload demands additional performance. And for Intel Core processors in the LGA2011 socket, Intel® Hyper-Threading Technology¹ allows each processor core to work on two tasks at the same time, improving multitasking, speeding up the workflow, and accomplishing more in less time.



  • Four Core / 8 Thread Processing
    Provides four complete execution cores in a single processor package, delivering 8 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 21 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 Technology¹
    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.
