¹ Hyper-Threading Technology requires a computer system with an Intel® Pentium® 4 processor or Intel® Core™ i7 processor supporting HT Technology and a Hyper-Threading Technology enabled chipset, BIOS and operating system. Performance will vary depending on the specific hardware and software you use. See for more information including details on which processors support HT Technology.
² Intel® EM64T requires a computer system with a processor, chipset, BIOS, operating system, device drivers and applications enabled for Intel EM64T. Processor will not operate (including 32-bit operation) without an Intel EM64T-enabled BIOS. Performance will vary depending on your hardware and software configurations. See for more information including details on which processors support Intel® EM64T or consult with your system vendor for more information.
³ 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.

About Intel Products

Intel Corporation (NASDAQ: INTC; SEHK: 4335) is the world's largest semiconductor company and the inventor of the x86 series of microprocessors, the processors found in many personal computers. Founded in 1968 as Integrated Electronics Corporation and based in Santa Clara, California, USA, Intel also makes motherboard chipsets, network cards and ICs, flash memory, graphic chips, embedded processors, and other devices related to communications and computing. Originally known primarily to engineers and technologists, Intel's successful "Intel Inside" advertising campaign of the 1990s made it and its Pentium processor household names. During the 1990s, Intel invested heavily in new microprocessor designs and in fostering the rapid growth of the PC industry. During this period Intel became the dominant supplier of microprocessors for PCs.
