So Intel has caught up with AMD by copying their 64 bit instruction set and copying their architecture.

Some numbers jumped out at me. It was clear that Intel’s EM64T architecture present in the Cyberpower, Dell, and Compaq systems was not helping encoding times in Movie Maker at all while running 64-bit Vista. However, I did see an improvement in Media Player while encoding CDs. Perplexed, I contacted Intel and asked them if they could offer an explanation as to this phenomenon. I was told that different compilers could have been used, and Microsoft may not have optimized certain applications at this point for EM64T. Being that this is a beta release, I am happy to accept this explanation at this point. Moreover, since I did see a marked improvement in audio encoding times, I can at least point to a scenario where an application is taking advantage of Intel’s 64-bit architecture.

So, EM64T isn't an exact copy of AMD's 64bit technology... :)

Th implementation may not be the same, but the instruction set is the same. Intel was going to have a propriatary 64 bit instruction set, but when AMD beat them to the gate by over a year, they had to give up. Windows 64 sailed without them.
