Δ Intel processor numbers are not
a measure of performance. Processor numbers differentiate features
within each processor family, not across different processor families.

† Look for systems with the
Intel® Pentium® 4 Processor with HT Technology logo and also including
an Intel® 925X or 915 Express Chipset (see the product spec sheet or
ask your salesperson). Performance and functionality will vary
depending on (i) the specific hardware and software you use and (ii)
the feature enabling/system configuration by your system vendor. See
http://www.intel.com/info/hyperthreading for information on HT
Technology or consult your system vendor for more information.
± Intel Virtualization
Technology requires a computer system with a processor, chipset, BIOS,
virtual machine monitor (VMM) and applications enabled for
virtualization technology. Functionality, performance or other
virtualization technology benefits will vary depending on hardware and
software configurations. Virtualization technology-enabled BIOS and
VMM applications are currently in development.
ø 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 www.intel.com/info/em64t for more
information including details on which processors support Intel EM64T
or consult with your system vendor 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
∗ Enhanced HALT State (C1E) and
Enhanced Intel SpeedStep® Technology (EIST) for specified units of
this processor available Q2/06. See the Processor Spec Finder at
