Windows XP Professional 64 Bit Edition
   
 Windows XP 64-Bit Edition will run on the Intel Itanium processor
 as the platform for workstation users who are reaching the memory
 limits of 32-bit systems. The key difference between 32-bit and
 64-bit Windows XP-based computing lies in the 64-bit versions
 ability to use much more system memory. Windows XP 64-Bit Edition
 will initially support up to 16 gigabytes of RAM and up to eight
 terabytes of virtual memory. Physical memory support will grow in
 the future as hardware capabilities expand. Data in memory is
 accessed thousands of times faster than it is on a disk drive,
 offering a tremendous performance benefit for applications that are
 developed to use this greater system memory. In addition,
 Windows XP 64-Bit Edition has been designed to take advantage of
 the superior floating point capabilities of the Itanium processor.
