What is x64?

The term x64 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. The x64 architecture, when combined with Windows XP Professional x64 Edition, can run the thousands of 32-bit programs available today. The x64 architecture also lets a developer enter whole new areas with the advanced capabilities that 64-bit processing makes possible.

The biggest difference between x64 and other 64-bit processors is that x64 processors are compatible at the hardware level with 32-bit, x86 processors. There are currently two basic x64 processor families:
•

AMD's amd64
•

Intel's EM64T

From AMD, this includes the Athlon 64, Athlon 64 FX, Mobile Athlon 64, Turion 64, and Opteron processors. From Intel, this includes the Xeon with EM64T and Pentium 4 with EM64T processors. The two architectures are binary compatible, allowing Windows XP Professional x64 Edition to use a single version to support both.

Description of Windows XP Professional x64 Edition

Windows XP Professional x64 Edition is a near feature-complete version of Windows XP Professional that runs on x64 processors. Windows XP Professional x64 Edition supports 128 GB of RAM and 16 terabytes of virtual memory address space, as compared to 4 GB of both physical RAM and virtual memory address space for 32-bit Windows XP Professional.

Windows XP Professional x64 Edition runs 32-bit applications in the Windows on Windows 64 (WOW64) subsystem providing compatibility with the more than 10,000 existing 32-bit Windows applications while enabling new 64-bit applications.

Who is the initial audience?

This release of Windows XP Professional x64 Edition is primarily designed for 32-bit system users who are pushing the memory limits of their systems and want the new 64-bit technology to improve their PC or workstation performance. The core audience for Windows XP Professional x64 Edition includes these groups:
•

Developers
•

Gamers
•

Graphics, audio, and media artists
•

CAD/CAM users
•

Enthusiasts

I fall under this last one more than any other. I'm moving my main workstation to the new x64 box I built a few months ago. But one of the programs I've seen running on x64 that I find really exciting is SONAR 4, a professional music studio audio-mixing application from Cakewalk. As Ron Kuper, Chief Technical Officer for Cakewalk, discovered when they did an internal port of SONAR 4 to x64, they got a completely unexpected 20-30% performance boost even though SONAR 4 wasn't memory space constrained. But the additional efficiency of the x64 processor architecture, with its additional general purpose and floating point registers, had a significant impact on the speed and responsiveness of SONAR 4.
