64-bit Performance
Windows XP features performance that simply cannot be matched in the 32-bit realm. Native applications are able to deliver data more quickly, resulting in enhanced performance. The OS supports systems with up to 128 GB of RAM!
Multi-processor Support
The OS fully supports multi-processor and multi-core systems. This is a boon to users in scientific and engineering fields, as their work often requires much more power and precision than standard desktop operating systems can deliver.
32-bit Emulation
Windows XP features the WOW64 x86 emulation layer. This transparent system allows you to run legacy 32-bit applications.
