Microsoft has confirmed that Windows XP 64 has gone gold. This means that MSDN subscribers can now download the final version of the OS while retail may have to wait a few weeks. This release should finally demonstrate to owners of 64-bit processors the benefits of their investment.
The new Microsoft OS has been extensively delayed reaching gold status, oddly enough, just as Intel is ready with its 64-bit chips. However delayed, the creation of an OS providing a pure 64-bit environment for such processors should have a significant impact on overall performance and should allow new exciting features to kick-in. Most of those will probably begin appearing in the guise of service packs after developers get some experience and a proper feel for the environment.
AMD currently has 64-bit server, desktop and mobile processors available so it covers the full range of options while Intel, back in February announced the 600 series of Pentium 4 Extreme Edition HT 64-bit processors.
The creation of a proper and stable OS is a lengthy process and although AMD must feel bitter for having a product, essentially, handicapped by the delays, the company will have to understand the intricacies involved.
If you haven't heard that much about 64-bit computing yet, make a note as today is the day when it goes mainstream and since all future processors are destined to be 64-bit only, (unlike current backwards compatible ones) prepare to be outdated. Just as a sign of the way things are heading you should bear in mind that all 3 major next-generation consoles will feature 64-bit processors.
