Intel® 64 and IA-32 architectures software developer's manuals These manuals describe the architecture and programming environment of the Intel® 64 and IA-32 processors. Electronic versions of these documents allow you to quickly get to the information you need, print only the pages you want and are available in PDF format or on CD-ROM.
Intel® processor numbers are not a measure of performance. Processor numbers differentiate features within each processor family, not across different processor families. See www.intel.com/products/processor_number/eng/ for details.
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.
