A report from News.com quoting Marty Seyer, vice president and general manager of AMD’s microprocessor business unit claims that Microsoft will release its Windows operating system that will be able to take advantage of AMD’s 64-bit processors Opteron and Athlon 64 in late 2003 or early 2004.

The beta version of the Windows for AMD64 operating system will become available in late Q3, according to AMD, a bit later than originally estimated, though, it should not generally postpone the release of the final version, according to observers. The final version is expected to come in Q4 2003 or Q1 2004.

A representative from Redmond, Washington-based software giant confirmed that the company will offer desktop and server versions of the 64-bit Windows for the AMD chips, but declined to comment on any exact timetable.

Earlier this year we reported that there is a lot of various software for x86-64 processors to come, but probably a special version of Windows for 64-bit AMD chips is the most important one. As a result, we should probably expect the rise in sales of AMD Athlon 64 processor for desktop computers after the release of Windows for AMD64.
