Windows XP Professional 圆4 Edition is a near feature-complete version of Windows XP Professional that runs on 圆4 processors. Description of Windows XP Professional 圆4 Edition
The two architectures are binary compatible, allowing Windows XP Professional 圆4 Edition to use a single version to support both. From Intel, this includes the Xeon with EM64T and Pentium 4 with EM64T processors. There are currently two basic 圆4 processor families:įrom AMD, this includes the Athlon 64, Athlon 64 FX, Mobile Athlon 64, Turion 64, and Opteron processors. The biggest difference between 圆4 and other 64-bit processors is that 圆4 processors are compatible at the hardware level with 32-bit, x86 processors. The 圆4 architecture also lets a developer enter whole new areas with the advanced capabilities that 64-bit processing makes possible.
The 圆4 architecture, when combined with Windows XP Professional 圆4 Edition, can run the thousands of 32-bit programs available today. The term 圆4 is used to describe the 64-bit architecture developed by Advanced Micro Devices (AMD) and Intel to provide processors that are highly compatible with the x86 processors that have been the mainstay of personal computing. Windows XP Professional 圆4 Edition is designed to support up to two single or multicore 圆4 processors for maximum performance and scalability.ĭevelopers with 32-bit skills will be comfortable and quickly productive in the 64-bit Windows environment, finding it virtually identical to the development environment for 32-bit Windows. Windows XP Professional 圆4 Edition provides a rich platform to integrate 64-bit applications and existing 32-bit applications using the Windows on Windows 64 (WOW64) x86 emulation layer, providing customers with the ability to move to 64-bit computing without having to sacrifice their existing investment in 32-bit software and Windows expertise. Applications can preload substantially more data into virtual memory, allowing rapid access by the 64-bit processor. Windows XP Professional 圆4 Edition supports up to 128 gigabytes (GB) of RAM and 16 terabytes of virtual memory, enabling applications to run faster when working with large data sets. 64-bit native applications can deliver more data per clock cycle, making them run faster and more efficiently.
