Intel® Virtualization Technology (Intel® VT), Intel® Trusted Execution Technology (Intel® TXT), and Intel® 64 architecture require a computer system with a processor, chipset, BIOS, enabling software and/or operating system, device drivers and applications designed for these features. Performance will vary depending on your configuration. Contact your vendor for more information.Not all specified units of this processor support Enhanced Intel SpeedStep® Technology. See the Processor Spec Finder at ark.intel.com or contact your Intel representative for more information.Enabling Execute Disable Bit functionality requires a PC with a processor with Execute Disable Bit capability and a supporting operating system. Check with your PC manufacturer on whether your system delivers Execute Disable Bit functionality.

On September 8, 2009, Intel released the first Core i5 processor: The Core i5 750,[2] which is a 2.66 GHz quad-core Lynnfield processor with Hyper-threading disabled. Lynnfield Core i5 processors have an 8 MB L3 cache, a DMI bus running at 2.5 GT/s and support for dual-channel DDR3-800/1066/1333 memory. The same processors with different sets of features (Hyper-Threading and other clock frequencies) enabled are sold as Core i7-8xx and Xeon 3400-series processors, which should not be confused with high-end Core i7-9xx and Xeon 3500-series processors based on Bloomfield.

The Intel® Core™ i7 processor delivers best-in-class performance for the most demanding applications. This quad-core processor features 8-way multitasking capability and additional L3 cache. With adaptive performance and built-in visual capabilities this 2nd generation processor brings more intelligence to your PC.
2nd generation Intel® Core™ i7 processors feature Intel® Turbo Boost Technology 2.0◊ and Intel® Hyper-Threading Technology◊, enabling required security applications and protocols to run efficiently in the background without compromising productivity.
