No there isn't and this is history rewriting, even if you genuinely believe this could be this is not what happened at all. First it's pretty clear, seeing how Intel played their game with the x86 licence, they would never have voluntarily made themselves depend on AMD licensing them x86_64 for the next decades like they are now. Second, back then Intel was very seriously asking / pressuring microsoft into not supporting amd64 extension and wait for intel64 to be released instead. But intel64 was late and delayed, pentium 4 kept hitting brick walls while Athlon started reigning supreme, opteron was starting to be noticed on the server side, and IA-64 was not getting outside of niche territory. Meanwhile linux started making some real pressure on the server andbusiness demands meant microsoft needed to show a windows that supported 64 bits on commodity hardware, asap. Amd64 was ready and the chip using it were cheap and powerfull, so microsoft made their choice.
